DIVIDENDS AND DISTRIBUTIONS
The fund expects that its distributions, if any, will consist of both capital gains and ordinary income.

DIVIDENDS

The fund generally declares and pays dividends from net investment income, if any, annually.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of the fund's normal investment activities and cash flows.

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to

THE AIM FUNDS

the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

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

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

- All funds, Class Y shares

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

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

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current, former or retired trustee, director, officer or employee (or immediate family member of a current, former or retired trustee, director, officer or employee) of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. This includes any foundation, trust or employee benefit plan maintained by any of the persons listed above.

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Investors who purchase shares through a fee-based advisory account with an approved financial intermediary or any current or retired trustee, director, officer or employee of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. In a fee based advisory program, a financial intermediary typically charges each investor a fee based on the value of the investor's account in exchange for servicing that account.

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

THE AIM FUNDS

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code.

- Insurance company separate accounts.

No investor will pay an initial sales charge in the following circumstances:

- When buying Class A shares of AIM Tax-Exempt Cash Fund and Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund.

- When reinvesting dividends and distributions.

- When exchanging shares of one fund, that were previously assessed a sales charge, for shares of another fund.

- As a result of a fund's merger, consolidation, or acquisition of the assets of another fund.

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P, R or Y) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

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

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B, P, Y and Institutional redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan. In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited

THE AIM FUNDS

Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

YEAR SINCE PURCHASE MADE:   CLASS B   CLASS C
-------------------------   -------   -------
First                          5%        1%

Sixth                          1        None
Seventh and following         None      None

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

- Class Y shares of any fund.

THE AIM FUNDS

CDSCS UPON CONVERTING TO CLASS Y SHARES

If shares that are subject to a CDSC are converted to Class Y shares, the applicable CDSC will be assessed prior to conversion.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund
AIM European Growth Fund
AIM European Small Company Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Health Care Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM Gold & Precious Metals Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the

THE AIM FUNDS

transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

Invesco Aim Distributors acts as the prototype sponsor for certain types of retirement plan documents. These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type. Contact your financial advisor or other intermediary for details.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

                              The transfer agent may require that you provide additional documentation, or information, such as
                              corporate resolutions or powers of attorney, if applicable. If you are redeeming from an IRA or
                              other type of retirement account, you must complete the appropriate distribution form.

By Telephone                  Call the transfer agent at 1-800-959-4246. You will be allowed to redeem by telephone if:

                              -    Your redemption proceeds are to be mailed to your address on record (and there has been no change
                                   in your address of record within the last 30 days) or transferred electronically to a
                                   pre-authorized checking account;

                              -    You do not hold physical share certificates;

                              -    You have not previously declined the telephone redemption privilege.

                              You may, in limited circumstances, initiate a redemption from an Invesco Aim IRA account by telephone.
                              Redemptions from other types of retirement plan accounts may be initiated only in writing and require
                              the completion of the appropriate distribution form.

Automated Investor Line       Call the Invesco Aim 24-hour Automated Investor Line at 1-800-246-5463. You may place your redemption

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares, Class Y shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares, Class Y shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

EXCHANGE FROM                                    EXCHANGE TO
-------------             --------------------------------------------------------

* You may exchange your AIM Cash Reserve Shares, Class A shares, Class A3 shares Class C shares, Class P shares or Investor Class shares for Class Y shares of the same fund if you otherwise qualify to buy that fund's Class Y shares. Please consult your financial advisor to discuss the tax implications, if any, of all exchanges into Class Y shares of the same fund.

EXCHANGES NOT PERMITTED

The following exchanges are not permitted:

- Investor Class shares cannot be exchanged for Class A shares of any fund which offers Investor Class shares.

- Exchanges into Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund (also known as the Category III funds) are not permitted.

- Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund cannot be exchanged for Class A3 shares of those funds.

- AIM Cash Reserve Shares cannot be exchanged for Class B, C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any fund.

- AIM Cash Reserve shares, Class A shares, Class A3 shares, Class C shares or Investor Class shares of one fund can not be exchanged for Class Y shares of a different fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

THE AIM FUNDS

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

DIVIDENDS AND DISTRIBUTIONS

The fund expects that its distributions, if any, will consist of both capital gains and ordinary income.

DIVIDENDS

The fund generally declares and pays dividends from net investment income, if any, annually.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of the fund's normal investment activities and cash flows.

FUTURE LIMITED FUND OFFERING
Due to the sometimes limited availability of common stocks in developing companies that meet the investment criteria for the fund, the fund may limit public sale of its shares to certain new investors after assets reach approximately $2 billion.

The fund may resume sales of shares to new investors at some future date if the Board of Trustees determines that doing so would be in the best interest of the shareholders.

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to

THE AIM FUNDS

the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

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

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

- All funds, Class Y shares

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

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

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current, former or retired trustee, director, officer or employee (or immediate family member of a current, former or retired trustee, director, officer or employee) of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. This includes any foundation, trust or employee benefit plan maintained by any of the persons listed above.

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Investors who purchase shares through a fee-based advisory account with an approved financial intermediary or any current or retired trustee, director, officer or employee of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. In a fee based advisory program, a financial intermediary typically charges each investor a fee based on the value of the investor's account in exchange for servicing that account.

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

THE AIM FUNDS

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code.

- Insurance company separate accounts.

No investor will pay an initial sales charge in the following circumstances:

- When buying Class A shares of AIM Tax-Exempt Cash Fund and Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund.

- When reinvesting dividends and distributions.

- When exchanging shares of one fund, that were previously assessed a sales charge, for shares of another fund.

- As a result of a fund's merger, consolidation, or acquisition of the assets of another fund.

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P, R or Y) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

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

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B, P, Y and Institutional redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan. In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited

THE AIM FUNDS

Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

- Class Y shares of any fund.

THE AIM FUNDS

CDSCS UPON CONVERTING TO CLASS Y SHARES

If shares that are subject to a CDSC are converted to Class Y shares, the applicable CDSC will be assessed prior to conversion.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund
AIM European Growth Fund
AIM European Small Company Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Health Care Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM Gold & Precious Metals Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the

THE AIM FUNDS

transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

Invesco Aim Distributors acts as the prototype sponsor for certain types of retirement plan documents. These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type. Contact your financial advisor or other intermediary for details.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares, Class Y shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares, Class Y shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

EXCHANGE FROM                                    EXCHANGE TO

* You may exchange your AIM Cash Reserve Shares, Class A shares, Class A3 shares Class C shares, Class P shares or Investor Class shares for Class Y shares of the same fund if you otherwise qualify to buy that fund's Class Y shares. Please consult your financial advisor to discuss the tax implications, if any, of all exchanges into Class Y shares of the same fund.

EXCHANGES NOT PERMITTED

The following exchanges are not permitted:

- Investor Class shares cannot be exchanged for Class A shares of any fund which offers Investor Class shares.

- Exchanges into Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund (also known as the Category III funds) are not permitted.

- Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund cannot be exchanged for Class A3 shares of those funds.

- AIM Cash Reserve Shares cannot be exchanged for Class B, C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any fund.

- AIM Cash Reserve shares, Class A shares, Class A3 shares, Class C shares or Investor Class shares of one fund can not be exchanged for Class Y shares of a different fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

THE AIM FUNDS

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

DIVIDENDS AND DISTRIBUTIONS
The fund expects that its distributions, if any, will consist primarily of capital gains.

DIVIDENDS

The fund generally declares and pays dividends from net investment income, if any, annually.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of the fund's normal investment activities and cash flows.

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to

THE AIM FUNDS

the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

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

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

- All funds, Class Y shares

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

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

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current, former or retired trustee, director, officer or employee (or immediate family member of a current, former or retired trustee, director, officer or employee) of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. This includes any foundation, trust or employee benefit plan maintained by any of the persons listed above.

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Investors who purchase shares through a fee-based advisory account with an approved financial intermediary or any current or retired trustee, director, officer or employee of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. In a fee based advisory program, a financial intermediary typically charges each investor a fee based on the value of the investor's account in exchange for servicing that account.

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

THE AIM FUNDS

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code.

- Insurance company separate accounts.

No investor will pay an initial sales charge in the following circumstances:

- When buying Class A shares of AIM Tax-Exempt Cash Fund and Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund.

- When reinvesting dividends and distributions.

- When exchanging shares of one fund, that were previously assessed a sales charge, for shares of another fund.

- As a result of a fund's merger, consolidation, or acquisition of the assets of another fund.

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P, R or Y) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

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

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B, P, Y and Institutional redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan. In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited

THE AIM FUNDS

Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

YEAR SINCE PURCHASE MADE:   CLASS B   CLASS C
-------------------------   -------   -------
First                          5%        1%
Second                         4        None
Third                          3        None
Fourth                         3        None
Fifth                          2        None
Sixth                          1        None
Seventh and following         None      None

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

- Class Y shares of any fund.

THE AIM FUNDS

CDSCS UPON CONVERTING TO CLASS Y SHARES

If shares that are subject to a CDSC are converted to Class Y shares, the applicable CDSC will be assessed prior to conversion.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund
AIM European Growth Fund
AIM European Small Company Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Health Care Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM Gold & Precious Metals Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the

THE AIM FUNDS

transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

Invesco Aim Distributors acts as the prototype sponsor for certain types of retirement plan documents. These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type. Contact your financial advisor or other intermediary for details.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

                              -    Original signatures of all registered owners/trustees;

                              The transfer agent may require that you provide additional documentation, or information, such as
                              corporate resolutions or powers of attorney, if applicable. If you are redeeming from an IRA or
                              other type of retirement account, you must complete the appropriate distribution form.

By Telephone                  Call the transfer agent at 1-800-959-4246. You will be allowed to redeem by telephone if:

                              -    Your redemption proceeds are to be mailed to your address on record (and there has been no change
                                   in your address of record within the last 30 days) or transferred electronically to a
                                   pre-authorized checking account;

                              -    You do not hold physical share certificates;

                              -    You have not previously declined the telephone redemption privilege.

                              You may, in limited circumstances, initiate a redemption from an Invesco Aim IRA account by telephone.
                              Redemptions from other types of retirement plan accounts may be initiated only in writing and require
                              the completion of the appropriate distribution form.

Automated Investor Line       Call the Invesco Aim 24-hour Automated Investor Line at 1-800-246-5463. You may place your redemption

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares, Class Y shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares, Class Y shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

Please consult your financial advisor to discuss the tax implications, if any, of all exchanges into Class Y shares of the same fund.

EXCHANGES NOT PERMITTED

The following exchanges are not permitted:

- Investor Class shares cannot be exchanged for Class A shares of any fund which offers Investor Class shares.

- Exchanges into Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund (also known as the Category III funds) are not permitted.

- Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund cannot be exchanged for Class A3 shares of those funds.

- AIM Cash Reserve Shares cannot be exchanged for Class B, C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any fund.

- AIM Cash Reserve shares, Class A shares, Class A3 shares, Class C shares or Investor Class shares of one fund can not be exchanged for Class Y shares of a different fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

THE AIM FUNDS

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

DIVIDENDS AND DISTRIBUTIONS

The fund expects that its distributions, if any, will consist of both capital gains and ordinary income.

DIVIDENDS

The fund generally declares dividends quarterly and pay dividends from net investment income, if any, quarterly.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of the fund's normal investment activities and cash flows.

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to

THE AIM FUNDS

the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

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

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

- All funds, Class Y shares

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

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

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current, former or retired trustee, director, officer or employee (or immediate family member of a current, former or retired trustee, director, officer or employee) of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. This includes any foundation, trust or employee benefit plan maintained by any of the persons listed above.

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Investors who purchase shares through a fee-based advisory account with an approved financial intermediary or any current or retired trustee, director, officer or employee of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. In a fee based advisory program, a financial intermediary typically charges each investor a fee based on the value of the investor's account in exchange for servicing that account.

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

THE AIM FUNDS

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code.

- Insurance company separate accounts.

No investor will pay an initial sales charge in the following circumstances:

- When buying Class A shares of AIM Tax-Exempt Cash Fund and Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund.

- When reinvesting dividends and distributions.

- When exchanging shares of one fund, that were previously assessed a sales charge, for shares of another fund.

- As a result of a fund's merger, consolidation, or acquisition of the assets of another fund.

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P, R or Y) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

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

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B, P, Y and Institutional redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan. In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited

THE AIM FUNDS

Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

YEAR SINCE PURCHASE MADE:   CLASS B   CLASS C

First                          5%        1%

Seventh and following         None      None

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

- Class Y shares of any fund.

THE AIM FUNDS

CDSCS UPON CONVERTING TO CLASS Y SHARES

If shares that are subject to a CDSC are converted to Class Y shares, the applicable CDSC will be assessed prior to conversion.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund
AIM European Growth Fund
AIM European Small Company Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Health Care Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM Gold & Precious Metals Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the

THE AIM FUNDS

transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

Invesco Aim Distributors acts as the prototype sponsor for certain types of retirement plan documents. These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type. Contact your financial advisor or other intermediary for details.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

                              The transfer agent may require that you provide additional documentation, or information, such as
                              corporate resolutions or powers of attorney, if applicable. If you are redeeming from an IRA or
                              other type of retirement account, you must complete the appropriate distribution form.

By Telephone                  Call the transfer agent at 1-800-959-4246. You will be allowed to redeem by telephone if:

                              -    Your redemption proceeds are to be mailed to your address on record (and there has been no change
                                   in your address of record within the last 30 days) or transferred electronically to a
                                   pre-authorized checking account;

                              -    You do not hold physical share certificates;

                              -    Your redemption proceeds do not exceed $250,000 per fund; and

                              -    You have not previously declined the telephone redemption privilege.

                              You may, in limited circumstances, initiate a redemption from an Invesco Aim IRA account by telephone.
                              Redemptions from other types of retirement plan accounts may be initiated only in writing and require
                              the completion of the appropriate distribution form.

Automated Investor Line       Call the Invesco Aim 24-hour Automated Investor Line at 1-800-246-5463. You may place your redemption

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares, Class Y shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares, Class Y shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

* You may exchange your AIM Cash Reserve Shares, Class A shares, Class A3 shares Class C shares, Class P shares or Investor Class shares for Class Y shares of the same fund if you otherwise qualify to buy that fund's Class Y shares. Please consult your financial advisor to discuss the tax implications, if any, of all exchanges into Class Y shares of the same fund.

EXCHANGES NOT PERMITTED

The following exchanges are not permitted:

- Investor Class shares cannot be exchanged for Class A shares of any fund which offers Investor Class shares.

- Exchanges into Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund (also known as the Category III funds) are not permitted.

- Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund cannot be exchanged for Class A3 shares of those funds.

- AIM Cash Reserve Shares cannot be exchanged for Class B, C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any fund.

- AIM Cash Reserve shares, Class A shares, Class A3 shares, Class C shares or Investor Class shares of one fund can not be exchanged for Class Y shares of a different fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

THE AIM FUNDS

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

DIVIDENDS AND DISTRIBUTIONS
The fund expects that its distributions, if any, will consist of both capital gains and ordinary income.

DIVIDENDS

The fund generally declares and pays dividends from net investment income, if any, annually.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of the fund's normal investment activities and cash flows.

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to

THE AIM FUNDS

the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

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

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

- All funds, Class Y shares

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

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

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current, former or retired trustee, director, officer or employee (or immediate family member of a current, former or retired trustee, director, officer or employee) of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. This includes any foundation, trust or employee benefit plan maintained by any of the persons listed above.

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Investors who purchase shares through a fee-based advisory account with an approved financial intermediary or any current or retired trustee, director, officer or employee of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. In a fee based advisory program, a financial intermediary typically charges each investor a fee based on the value of the investor's account in exchange for servicing that account.

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

THE AIM FUNDS

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code.

- Insurance company separate accounts.

No investor will pay an initial sales charge in the following circumstances:

- When buying Class A shares of AIM Tax-Exempt Cash Fund and Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund.

- When reinvesting dividends and distributions.

- When exchanging shares of one fund, that were previously assessed a sales charge, for shares of another fund.

- As a result of a fund's merger, consolidation, or acquisition of the assets of another fund.

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P, R or Y) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

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

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B, P, Y and Institutional redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan. In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited

THE AIM FUNDS

Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

- Class Y shares of any fund.

THE AIM FUNDS

CDSCS UPON CONVERTING TO CLASS Y SHARES

If shares that are subject to a CDSC are converted to Class Y shares, the applicable CDSC will be assessed prior to conversion.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund
AIM European Growth Fund
AIM European Small Company Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Health Care Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM Gold & Precious Metals Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the

THE AIM FUNDS

transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

Invesco Aim Distributors acts as the prototype sponsor for certain types of retirement plan documents. These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type. Contact your financial advisor or other intermediary for details.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

                              corporate resolutions or powers of attorney, if applicable. If you are redeeming from an IRA or
                              other type of retirement account, you must complete the appropriate distribution form.

By Telephone                  Call the transfer agent at 1-800-959-4246. You will be allowed to redeem by telephone if:

                              -    Your redemption proceeds are to be mailed to your address on record (and there has been no change
                                   in your address of record within the last 30 days) or transferred electronically to a
                                   pre-authorized checking account;

                              -    You do not hold physical share certificates;

                              You may, in limited circumstances, initiate a redemption from an Invesco Aim IRA account by telephone.
                              Redemptions from other types of retirement plan accounts may be initiated only in writing and require
                              the completion of the appropriate distribution form.

Automated Investor Line       Call the Invesco Aim 24-hour Automated Investor Line at 1-800-246-5463. You may place your redemption
                              order after you have provided the bank instructions that will be requested.

By Internet                   Place your redemption request at www.invescoaim.com. You will be allowed to redeem by Internet if:

                              completion of the appropriate distribution form.

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares, Class Y shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares, Class Y shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

EXCHANGE FROM                                    EXCHANGE TO
-------------             --------------------------------------------------------

Class R                   Class R
Class Y                   Class Y

* You may exchange your AIM Cash Reserve Shares, Class A shares, Class A3 shares Class C shares, Class P shares or Investor Class shares for Class Y shares of the same fund if you otherwise qualify to buy that fund's Class Y shares. Please consult your financial advisor to discuss the tax implications, if any, of all exchanges into Class Y shares of the same fund.

EXCHANGES NOT PERMITTED

The following exchanges are not permitted:

- Investor Class shares cannot be exchanged for Class A shares of any fund which offers Investor Class shares.

- Exchanges into Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund (also known as the Category III funds) are not permitted.

- Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund cannot be exchanged for Class A3 shares of those funds.

- AIM Cash Reserve Shares cannot be exchanged for Class B, C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any fund.

- AIM Cash Reserve shares, Class A shares, Class A3 shares, Class C shares or Investor Class shares of one fund can not be exchanged for Class Y shares of a different fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

THE AIM FUNDS

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

DIVIDENDS AND DISTRIBUTIONS
The fund expects that its distributions, if any, will consist primarily of ordinary income.

DIVIDENDS

The fund generally declares dividends monthly and pays dividends from net investment income, if any, monthly.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of the fund's normal investment activities and cash flows.

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to

THE AIM FUNDS

the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

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

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

- All funds, Class Y shares

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

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

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current, former or retired trustee, director, officer or employee (or immediate family member of a current, former or retired trustee, director, officer or employee) of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. This includes any foundation, trust or employee benefit plan maintained by any of the persons listed above.

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Investors who purchase shares through a fee-based advisory account with an approved financial intermediary or any current or retired trustee, director, officer or employee of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. In a fee based advisory program, a financial intermediary typically charges each investor a fee based on the value of the investor's account in exchange for servicing that account.

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

THE AIM FUNDS

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code.

- Insurance company separate accounts.

No investor will pay an initial sales charge in the following circumstances:

- When buying Class A shares of AIM Tax-Exempt Cash Fund and Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund.

- When reinvesting dividends and distributions.

- When exchanging shares of one fund, that were previously assessed a sales charge, for shares of another fund.

- As a result of a fund's merger, consolidation, or acquisition of the assets of another fund.

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P, R or Y) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

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

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B, P, Y and Institutional redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan. In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited

THE AIM FUNDS

Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

YEAR SINCE PURCHASE MADE:   CLASS B   CLASS C
-------------------------   -------   -------
First                          5%        1%
Second                         4        None
Third                          3        None

Seventh and following         None      None

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

- Class Y shares of any fund.

THE AIM FUNDS

CDSCS UPON CONVERTING TO CLASS Y SHARES

If shares that are subject to a CDSC are converted to Class Y shares, the applicable CDSC will be assessed prior to conversion.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund
AIM European Growth Fund
AIM European Small Company Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Health Care Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM Gold & Precious Metals Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the

THE AIM FUNDS

transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

Invesco Aim Distributors acts as the prototype sponsor for certain types of retirement plan documents. These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type. Contact your financial advisor or other intermediary for details.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

                              The transfer agent may require that you provide additional documentation, or information, such as
                              corporate resolutions or powers of attorney, if applicable. If you are redeeming from an IRA or
                              other type of retirement account, you must complete the appropriate distribution form.

By Telephone                  Call the transfer agent at 1-800-959-4246. You will be allowed to redeem by telephone if:

                              -    Your redemption proceeds are to be mailed to your address on record (and there has been no change
                                   in your address of record within the last 30 days) or transferred electronically to a
                                   pre-authorized checking account;

                              You may, in limited circumstances, initiate a redemption from an Invesco Aim IRA account by telephone.
                              Redemptions from other types of retirement plan accounts may be initiated only in writing and require
                              the completion of the appropriate distribution form.

Automated Investor Line       Call the Invesco Aim 24-hour Automated Investor Line at 1-800-246-5463. You may place your redemption

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares, Class Y shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares, Class Y shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

* You may exchange your AIM Cash Reserve Shares, Class A shares, Class A3 shares Class C shares, Class P shares or Investor Class shares for Class Y shares of the same fund if you otherwise qualify to buy that fund's Class Y shares. Please consult your financial advisor to discuss the tax implications, if any, of all exchanges into Class Y shares of the same fund.

EXCHANGES NOT PERMITTED

The following exchanges are not permitted:

- Investor Class shares cannot be exchanged for Class A shares of any fund which offers Investor Class shares.

- Exchanges into Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund (also known as the Category III funds) are not permitted.

- Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund cannot be exchanged for Class A3 shares of those funds.

- AIM Cash Reserve Shares cannot be exchanged for Class B, C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any fund.

- AIM Cash Reserve shares, Class A shares, Class A3 shares, Class C shares or Investor Class shares of one fund can not be exchanged for Class Y shares of a different fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

THE AIM FUNDS

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

DIVIDENDS AND DISTRIBUTIONS
The fund expects that its distributions, if any, will consist primarily of capital gains.

DIVIDENDS

The fund generally declares and pays dividends from net investment income, if any, annually.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerable from year to year as a result of the fund's normal investment activities and cash flows.

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to

THE AIM FUNDS

the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

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

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

- All funds, Class Y shares

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

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

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current, former or retired trustee, director, officer or employee (or immediate family member of a current, former or retired trustee, director, officer or employee) of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. This includes any foundation, trust or employee benefit plan maintained by any of the persons listed above.

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Investors who purchase shares through a fee-based advisory account with an approved financial intermediary or any current or retired trustee, director, officer or employee of any AIM Fund or of Invesco Ltd. or any of its subsidiaries. In a fee based advisory program, a financial intermediary typically charges each investor a fee based on the value of the investor's account in exchange for servicing that account.

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

THE AIM FUNDS

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code.

- Insurance company separate accounts.

No investor will pay an initial sales charge in the following circumstances:

- When buying Class A shares of AIM Tax-Exempt Cash Fund and Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund.

- When reinvesting dividends and distributions.

- When exchanging shares of one fund, that were previously assessed a sales charge, for shares of another fund.

- As a result of a fund's merger, consolidation, or acquisition of the assets of another fund.

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P, R or Y) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

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

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B, P, Y and Institutional redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan. In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited

THE AIM FUNDS

Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

YEAR SINCE PURCHASE MADE:   CLASS B   CLASS C
-------------------------   -------   -------
First                          5%        1%

Sixth                          1        None
Seventh and following         None      None

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

- Class Y shares of any fund.

THE AIM FUNDS

CDSCS UPON CONVERTING TO CLASS Y SHARES

If shares that are subject to a CDSC are converted to Class Y shares, the applicable CDSC will be assessed prior to conversion.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund
AIM European Growth Fund
AIM European Small Company Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Health Care Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM Gold & Precious Metals Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the

THE AIM FUNDS

transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

Invesco Aim Distributors acts as the prototype sponsor for certain types of retirement plan documents. These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type. Contact your financial advisor or other intermediary for details.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

                              The transfer agent may require that you provide additional documentation, or information, such as
                              corporate resolutions or powers of attorney, if applicable. If you are redeeming from an IRA or
                              other type of retirement account, you must complete the appropriate distribution form.

By Telephone                  Call the transfer agent at 1-800-959-4246. You will be allowed to redeem by telephone if:

                              -    Your redemption proceeds are to be mailed to your address on record (and there has been no change
                                   in your address of record within the last 30 days) or transferred electronically to a
                                   pre-authorized checking account;

                              -    You do not hold physical share certificates;

                              -    You have not previously declined the telephone redemption privilege.

                              You may, in limited circumstances, initiate a redemption from an Invesco Aim IRA account by telephone.
                              Redemptions from other types of retirement plan accounts may be initiated only in writing and require
                              the completion of the appropriate distribution form.

Automated Investor Line       Call the Invesco Aim 24-hour Automated Investor Line at 1-800-246-5463. You may place your redemption

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares, Class Y shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares, Class Y shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

* You may exchange your AIM Cash Reserve Shares, Class A shares, Class A3 shares Class C shares, Class P shares or Investor Class shares for Class Y shares of the same fund if you otherwise qualify to buy that fund's Class Y shares. Please consult your financial advisor to discuss the tax implications, if any, of all exchanges into Class Y shares of the same fund.

EXCHANGES NOT PERMITTED

The following exchanges are not permitted:

- Investor Class shares cannot be exchanged for Class A shares of any fund which offers Investor Class shares.

- Exchanges into Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund (also known as the Category III funds) are not permitted.

- Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund cannot be exchanged for Class A3 shares of those funds.

- AIM Cash Reserve Shares cannot be exchanged for Class B, C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any fund.

- AIM Cash Reserve shares, Class A shares, Class A3 shares, Class C shares or Investor Class shares of one fund can not be exchanged for Class Y shares of a different fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

THE AIM FUNDS

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

DIVIDENDS AND DISTRIBUTIONS
The fund expects that its distributions, if any, will consist primarily of capital gains.

DIVIDENDS

The fund generally declares and pays dividends from net investment income, if any, annually.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of the fund's normal investment activities and cash flows.

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to

THE AIM FUNDS

the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

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

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

- All funds, Class Y shares

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

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