Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive a portion of the Fund’s management fee in an amount equal to the net management fee that Invesco earns on the Fund’s investments in certain affiliated funds. This waiver will have the effect of reducing the Acquired Fund Fees and Expenses that are indirectly borne by the Fund. Unless Invesco continues the fee waiver agreement, it will terminate on February 28, 2015. The fee waiver agreement cannot be terminated during its term.

2

Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating

Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Class A, Class B, Class C, Class R and Class Y shares to 1.22%, 1.97%, 1.97%, 1.47% and 0.97%, respectively, of the Fund's average daily net assets. Unless Invesco continues the fee waiver agreement, it will terminate on June 30, 2014. The fee waiver agreement cannot be terminated during its term.

Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class A	$692	$1,000	$1,330	$2,260
Class B	$726	$1,005	$1,411	$2,414
Class C	$326	$ 705	$1,211	$2,602
Class R	$176	$ 553	$ 956	$2,081
Class Y	$125	$ 399	$ 693	$1,530

You would pay the following expenses if you did not redeem your shares:

	1 Year	3 Years	5 Years	10 Years
Class A	$692	$1,000	$1,330	$2,260
Class B	$226	$ 705	$1,211	$2,414
Class C	$226	$ 705	$1,211	$2,602
Class R	$176	$ 553	$ 956	$2,081
Class Y	$125	$ 399	$ 693	$1,530

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 47% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests, under normal conditions, in derivatives and other commodity-linked instruments whose performance is expected to correspond to the performance of the underlying commodity, without investing directly in physical commodities. Commodities are assets that have tangible properties, such as oil, metals, and agricultural products. The Fund seeks to achieve its investment objective by investing in derivatives and other commodity-linked instruments that provide exposure to the following four sectors of the commodities markets: agricultural/livestock, energy, industrial metals and precious metals.

The portfolio managers manage the Fund’s portfolio using two different processes. One is strategic asset allocation, which the portfolio managers use to express their long term views of the commodities market. The portfolio managers apply their strategic process to, on average, approximately 80% of the Fund’s portfolio, and this portion of the Fund holds only long positions in derivatives. The other process is tactical asset allocation, which is used by the portfolio managers to reflect their shorter term views of the commodities market. The tactical asset allocation process will result in the Fund having long and short positions within the four sectors of the commodities markets in which the Fund invests. The strategic and tactical processes are intended to diversify portfolio risk in a variety of market conditions.

The portfolio managers will implement their investment decisions through the use of derivatives and other investments that create economic leverage. The Fund uses derivatives and other leveraged instruments to create and adjust exposure to commodities. The portfolio managers make these adjustments to balance risk exposure (as part of the strategic process) and to add long or short exposure to commodities (as part of the tactical process) when they believe it will benefit the Fund. Using derivatives allows the portfolio managers to implement their views more efficiently and to gain more exposure to commodities than investing in more traditional assets such as stocks and bonds would allow. The Fund holds long and short positions in derivatives. A long derivative position involves the Fund buying a derivative with the anticipation of a price increase of the underlying asset, and a short derivative position involves the Fund writing (selling) a derivative with the anticipation of a price decrease of the underlying asset. The Fund’s use of derivatives and the leveraged investment exposure created by the use of derivatives are expected to be significant and greater than most mutual funds.

The Fund’s net asset value is expected to be volatile because of the significant use of derivatives and other instruments that provide economic leverage including commodity-linked notes, exchange-traded funds (ETFs) and exchange-traded notes (ETNs). Higher volatility generally indicates higher risk and is often reflected by frequent and sometimes significant movements up and down in value.

The Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund did not use derivatives or other instruments that have an economic leveraging effect. Economic leveraging tends to magnify, sometimes significantly depending on the amount of leverage used, the effect of any increase or decrease in the Fund’s exposure to commodities and may cause the Fund’s net asset value to be more volatile than a fund that does not use leverage. For example, if the Adviser gains exposure to commodities through an instrument that provides leveraged exposure to commodities, and that leveraged instrument increases in value, the gain to the Fund will be magnified; however, if the leveraged instrument decreases in value, the loss to the Fund will be magnified.

The Adviser’s investment process has three steps. The first step involves asset selection within four commodity sectors (agricultural/livestock, energy, industrial metals and precious metals). The portfolio managers select investments to represent each of the four commodity sectors from a universe of investments in over twenty separate sub-sectors. The selection process (1) evaluates a particular investment’s theoretical case for long-term excess returns relative to cash; (2) screens

the identified investments against minimum liquidity criteria; and (3) reviews the expected correlation among the investments, meaning the likelihood that the value of the investments will move in the same direction at the same time, and the expected risk of each investment to determine whether the selected investments are likely to improve the expected risk adjusted return of the Fund.

Using a systematic approach based on fundamental principles, the portfolio management team analyzes the investments, considering the following factors: valuation, economic environment and historic price movements. Regarding valuation, the portfolio managers evaluate whether investments are attractively priced relative to fundamentals. Next, the portfolio managers assess the economic environment and consider the effect that monetary policy and other determinants of economic growth, inflation and market volatility will have on the investments. Lastly, the portfolio managers assess the impact of historic price movements for the investments on likely future returns.

The second step in the investment process involves portfolio construction. The portfolio managers use their own estimates for risk and correlation to weight the investments to construct a risk-balanced portfolio. Periodically, the management team re-estimates the risk contributed by each investment and re-balances the portfolio; the portfolio also may be rebalanced when the Fund makes new investments.

Utilizing the results from the analysis described above, the portfolio managers determine tactical short-term over-weight (buying additional investments relative to the strategic allocation) and under-weight (selling investments relative to the strategic allocation) positions for investments across and within the four commodity sectors. The portfolio managers then attempt to control the frequency, depth and duration of portfolio losses and manage the risk contribution from the various investments with the proprietary risk-balancing process.

In the third step of the investment process, the portfolio managers calculate the estimated risk of the portfolio and scale the positions accordingly in order to construct a portfolio with a targeted risk profile. When the tactical position is negative for an investment and its size is larger than the strategic position for that investment, the result is a short derivative position. The size and number of short derivative positions held by the Fund will vary with the market environment. In some cases there will be no short derivative positions in the Fund. The Fund’s long positions in derivative instruments generally will benefit from an increase in the price of the underlying investment. The Fund’s short positions in derivative instruments generally will benefit from a decrease in the price of the underlying investment.

The Fund’s commodity exposure will be achieved through investments in ETFs, commodity futures and swaps, ETNs and commodity-linked notes, some or all of which will be owned through Invesco Cayman Commodity Fund III Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (Subsidiary).

The Fund will invest in the Subsidiary to gain exposure to commodities markets. The Subsidiary, in turn, will invest in futures, swaps, commodity-linked notes, ETFs and ETNs. The Subsidiary is advised by the Adviser, has the same investment objective as the Fund and generally employs the same investment strategy. Unlike the Fund, however, the Subsidiary may invest without limitation in commodity-linked derivatives and other securities that may provide leveraged and non-leveraged exposure to commodities. The Subsidiary holds cash and can invest in cash equivalent instruments, including affiliated money market funds, some or all of which may serve as margin or collateral for the Subsidiary’s derivative positions. Because the Subsidiary is wholly-owned by the Fund, the Fund will be subject to the risks associated with any investment by the Subsidiary.

The Fund generally will maintain 50% to 100% of its total assets (including assets held by the Subsidiary) in cash and cash equivalent instruments, including affiliated money market funds, as margin or collateral for the Fund’s obligations under derivative transactions. The larger the value of the Fund’s derivative positions, as opposed to positions held in

non-derivative instruments, the more the Fund will be required to maintain cash and cash equivalents as margin or collateral for such derivatives.

The derivative instruments in which the Fund will principally invest will include but are not limited to futures and swap agreements.

Principal Risks of Investing in the Fund

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

Commodities Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level. The Fund has received a private letter ruling from the Internal Revenue Service confirming that income derived from the Fund’s investment in a form of commodity-linked note constitutes qualifying income to the Fund. The Fund also has applied to the Internal Revenue Service for a private letter ruling relating to the Subsidiary. The Internal Revenue Service has issued a number of similar letter rulings, including to another Invesco fund (upon which only the fund that received the private letter ruling can rely), which indicate that income from a mutual fund’s investment in a wholly owned foreign subsidiary that invests in commodity-linked derivatives, such as the Subsidiary, constitutes qualifying income. However, the Internal Revenue Service suspended issuance in July 2011 of any further private letter rulings pending a review of its position. Should the Internal Revenue Service issue guidance, or Congress enact legislation, that adversely affects the tax treatment of the Fund’s use of commodity-linked notes, or the Subsidiary (which guidance might be applied retroactively to the Fund’s investment in the Subsidiary), it could limit the Fund’s ability to pursue its investment strategy and the Fund might not qualify as a regulated investment company for one or more years. In this event, the Fund’s Board of Trustees may authorize a significant change in investment strategy or Fund liquidation. The Fund also may incur transaction and other costs to comply with any new or additional guidance from the Internal Revenue Service.

Commodity-Linked Notes Risk. The Fund's investments in commodity-linked notes may involve substantial risks, including risk of loss of a significant portion of their principal value. In addition to risks associated with the underlying commodities, they may be subject to additional special risks, such as the lack of a secondary trading market and temporary price distortions due to speculators and/or the continuous rolling over of futures contracts underlying the notes. Commodity-linked notes are also subject to counterparty risk, which is the risk that the other party to the contract will not fulfill its contractual obligation to complete the transaction with the Fund.

Commodity Risk. The Fund will concentrate its investments in commodities markets. The Fund’s significant investment exposure to the commodities markets, and/or a particular sector of the commodities markets, which may subject the Fund to greater volatility than investments in traditional securities, such as stocks and bonds. The commodities markets may fluctuate widely based on a variety of factors, including changes in overall market movements, domestic and foreign political and economic events and policies, war, acts of terrorism, changes in domestic or foreign interest rates and/or investor expectations concerning interest rates, domestic and foreign inflation rates and investment and trading activities of mutual funds, hedge funds and commodities funds. Prices of various commodities may also be affected by factors such as drought, floods, weather, livestock disease, embargoes, tariffs and other regulatory developments. The prices of commodities can also fluctuate widely due to

supply and demand disruptions in major producing or consuming regions. Because the Fund’s performance is linked to the performance of potentially volatile commodities, investors should be willing to assume the risks of potentially significant fluctuations in the value of the Fund’s shares.

Correlation Risk. Changes in the value of two investments or asset classes may not track or offset each other in the manner anticipated by the portfolio managers. Because the Fund’s investment strategy seeks to balance risk across the four sectors of the commodities markets and, within each commodity sector, to balance risk across different commodities, to the extent either the four sectors of the commodities markets or the selected commodities are correlated in a way not anticipated by the portfolio managers the Fund’s risk allocation process may not succeed in achieving its investment objective.

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

Derivatives Risk. The value of a derivative instrument depends largely on (and is derived from) the value of an underlying security, currency, commodity, interest rate, index or other asset (each referred to as an underlying asset). In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage and liquidity risks. Counterparty risk is the risk that the counterparty to the derivative contract will default on its obligation to pay the Fund the amount owed or otherwise perform under the derivative contract. Derivatives create leverage risk because they do not require payment up front equal to the economic exposure created by owning the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be harder to value, less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. Also, derivatives used for hedging or to gain or limit exposure to a particular market segment may not provide the expected benefits, particularly during adverse market conditions. These risks are greater for the Fund than most other mutual funds because the Fund will implement its investment strategy primarily through derivative instruments rather than direct investments in stocks and bonds.

Exchange-Traded Funds Risk. An investment by the Fund in exchange-traded funds generally presents the same primary risks as an investment in a mutual fund. In addition, an exchange-traded fund may be subject to the following: (1) a discount of the exchange-traded fund’s shares to its net asset value; (2) failure to develop an active trading market for the exchange-traded fund’s shares; (3) the listing exchange halting trading of the exchange-traded fund’s shares; (4) failure of the exchange-traded fund’s shares to track the referenced asset; and (5) holding troubled securities in the referenced index or basket of investments. Exchange-traded funds may involve duplication of management fees and certain other expenses, as the Fund indirectly bears its proportionate share of any expenses paid by the exchange-traded funds in which it invests. Further, certain of the exchange-traded funds in which the Fund may invest are leveraged. The more the Fund invests in such leveraged exchange-traded funds, the more this leverage will magnify any losses on those investments.

Exchange-Traded Notes Risk. Exchange-traded notes are subject to credit risk, including the credit risk of the issuer, and the value of the exchange-traded note may drop due to a downgrade in the issuer’s credit rating, despite the underlying market benchmark or strategy remaining unchanged. The value of an exchange-traded note may also be influenced by time to maturity, level of supply and demand for the exchange-traded note, volatility and lack of liquidity in the underlying market, changes in the

applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events that affect the referenced underlying market or strategy. Exchange-traded notes are also subject to the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund.

Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. This risk may be magnified due to the Fund's use of derivatives that provide leveraged exposure to government bonds.

Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. The Fund's significant use of derivative instruments may cause liquidity risk to be greater than other mutual funds that invest in more traditional assets such as stocks and bonds, which trade on markets with more market participants.

Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. Because the Fund's investment process relies heavily on its asset allocation process, market movements that are counter to the portfolio managers’ expectations may have a significant adverse effect on the Fund's net asset value. Further, the portfolio managers’ use of short derivative positions and instruments that provide economic leverage increases the volatility of the Fund's net asset value, which increases the potential of greater losses that may cause the Fund to liquidate positions when it may not be advantageous to do so.

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

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

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

Volatility Risk. The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund's net asset value per share to experience significant increases or declines in value over short periods of time.

Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of each of Class R5 and R6 shares to 0.97% of the Fund's average daily net assets. Unless Invesco continues the fee waiver agreement, it will terminate on June 30, 2014. The fee waiver agreement cannot be terminated during its term.

Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return

each year and that the Fund's operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class R5	$123	$393	$682	$1,508
Class R6	$115	$368	$640	$1,417

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 47% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests, under normal conditions, in derivatives and other commodity-linked instruments whose performance is expected to correspond to the performance of the underlying commodity, without investing directly in physical commodities. Commodities are assets that have tangible properties, such as oil, metals, and agricultural products. The Fund seeks to achieve its investment objective by investing in derivatives and other commodity-linked instruments that provide exposure to the following four sectors of the commodities markets: agricultural/livestock, energy, industrial metals and precious metals.

The portfolio managers manage the Fund’s portfolio using two different processes. One is strategic asset allocation, which the portfolio managers use to express their long term views of the commodities market. The portfolio managers apply their strategic process to, on average, approximately 80% of the Fund’s portfolio, and this portion of the Fund holds only long positions in derivatives. The other process is tactical asset allocation, which is used by the portfolio managers to reflect their shorter term views of the commodities market. The tactical asset allocation process will result in the Fund having long and short positions within the four sectors of the commodities markets in which the Fund invests. The strategic and tactical processes are intended to diversify portfolio risk in a variety of market conditions.

The portfolio managers will implement their investment decisions through the use of derivatives and other investments that create economic leverage. The Fund uses derivatives and other leveraged instruments to create and adjust exposure to commodities. The portfolio managers make these adjustments to balance risk exposure (as part of the strategic process) and to add long or short exposure to commodities (as part of the tactical process) when they believe it will benefit the Fund. Using derivatives allows the portfolio managers to implement their views more efficiently and to gain more exposure to commodities than investing in more traditional assets such as stocks and bonds would allow. The Fund holds long and short positions in derivatives. A long derivative position involves the Fund buying a derivative with the anticipation of a price increase of the underlying asset, and a short derivative position involves the Fund writing (selling) a derivative with the anticipation of a price decrease of the underlying asset. The Fund’s use of derivatives and the leveraged investment exposure created by the use of derivatives are expected to be significant and greater than most mutual funds.

The Fund’s net asset value is expected to be volatile because of the significant use of derivatives and other instruments that provide economic leverage including commodity-linked notes, exchange-traded funds (ETFs) and exchange-traded notes (ETNs). Higher volatility generally indicates higher risk and is often reflected by frequent and sometimes significant movements up and down in value.

The Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund did not use derivatives or other instruments that have an economic leveraging effect. Economic leveraging tends to magnify, sometimes significantly depending on the amount of leverage used, the effect of any increase or decrease in the Fund’s exposure to commodities and may cause the Fund’s net asset value to be more volatile than a fund that does not use leverage. For example, if the Adviser gains exposure to commodities through an instrument that provides leveraged exposure to commodities, and that leveraged instrument increases in value, the gain to the Fund will be magnified; however, if the leveraged instrument decreases in value, the loss to the Fund will be magnified.

The Adviser’s investment process has three steps. The first step involves asset selection within four commodity sectors (agricultural/livestock, energy, industrial metals and precious metals). The portfolio managers select investments to represent each of the four commodity sectors from a universe of investments in over twenty separate sub-sectors. The selection process (1) evaluates a particular investment’s theoretical case for long-term excess returns relative to cash; (2) screens the identified investments against minimum liquidity criteria; and (3) reviews the expected correlation among the investments, meaning the likelihood that the value of the investments will move in the same direction at the same time, and the expected risk of each investment to determine whether the selected investments are likely to improve the expected risk adjusted return of the Fund.

Using a systematic approach based on fundamental principles, the portfolio management team analyzes the investments, considering the following factors: valuation, economic environment and historic price movements. Regarding valuation, the portfolio managers evaluate whether investments are attractively priced relative to fundamentals. Next, the portfolio managers assess the economic environment and consider the effect that monetary policy and other determinants of economic growth, inflation and market volatility will have on the investments. Lastly, the portfolio managers assess the impact of historic price movements for the investments on likely future returns.

The second step in the investment process involves portfolio construction. The portfolio managers use their own estimates for risk and correlation to weight the investments to construct a risk-balanced portfolio. Periodically, the management team re-estimates the risk contributed by each investment and re-balances the portfolio; the portfolio also may be rebalanced when the Fund makes new investments.

Utilizing the results from the analysis described above, the portfolio managers determine tactical short-term over-weight (buying additional investments relative to the strategic allocation) and under-weight (selling investments relative to the strategic allocation) positions for investments across and within the four commodity sectors. The portfolio managers then attempt to control the frequency, depth and duration of portfolio losses and manage the risk contribution from the various investments with the proprietary risk-balancing process.

In the third step of the investment process, the portfolio managers calculate the estimated risk of the portfolio and scale the positions accordingly in order to construct a portfolio with a targeted risk profile. When the tactical position is negative for an investment and its size is larger than the strategic position for that investment, the result is a short derivative position. The size and number of short derivative positions held by the Fund will vary with the market environment. In some cases there will be no short derivative positions in the Fund. The Fund’s long positions in derivative instruments generally will benefit from an increase in the price of the underlying investment. The Fund’s short positions in derivative instruments generally will benefit from a decrease in the price of the underlying investment.

The Fund’s commodity exposure will be achieved through investments in ETFs, commodity futures and swaps, ETNs and commodity-linked notes, some or all of which will be owned through Invesco Cayman Commodity Fund III Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (Subsidiary).

The Fund will invest in the Subsidiary to gain exposure to commodities markets. The Subsidiary, in turn, will invest in futures, swaps, commodity-linked notes, ETFs and ETNs. The Subsidiary is advised by the Adviser, has the same investment objective as the Fund and generally employs the same investment strategy. Unlike the Fund, however, the Subsidiary may invest without limitation in commodity-linked derivatives and other securities that may provide leveraged and non-leveraged exposure to commodities. The Subsidiary holds cash and can invest in cash equivalent instruments, including affiliated money market funds, some or all of which may serve as margin or collateral for the Subsidiary’s derivative positions. Because the Subsidiary is wholly-owned by the Fund, the Fund will be subject to the risks associated with any investment by the Subsidiary.

The Fund generally will maintain 50% to 100% of its total assets (including assets held by the Subsidiary) in cash and cash equivalent instruments, including affiliated money market funds, as margin or collateral for the Fund’s obligations under derivative transactions. The larger the value of the Fund’s derivative positions, as opposed to positions held in non-derivative instruments, the more the Fund will be required to maintain cash and cash equivalents as margin or collateral for such derivatives.

The derivative instruments in which the Fund will principally invest will include but are not limited to futures and swap agreements.

Principal Risks of Investing in the Fund

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

Commodities Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level. The Fund has received a private letter ruling from the Internal Revenue Service confirming that income derived from the Fund’s investment in a form of commodity-linked note constitutes qualifying income to the Fund. The Fund also has applied to the Internal Revenue Service for a

private letter ruling relating to the Subsidiary. The Internal Revenue Service has issued a number of similar letter rulings, including to another Invesco fund (upon which only the fund that received the private letter ruling can rely), which indicate that income from a mutual fund’s investment in a wholly owned foreign subsidiary that invests in commodity-linked derivatives, such as the Subsidiary, constitutes qualifying income. However, the Internal Revenue Service suspended issuance in July 2011 of any further private letter rulings pending a review of its position. Should the Internal Revenue Service issue guidance, or Congress enact legislation, that adversely affects the tax treatment of the Fund’s use of commodity-linked notes, or the Subsidiary (which guidance might be applied retroactively to the Fund’s investment in the Subsidiary), it could limit the Fund’s ability to pursue its investment strategy and the Fund might not qualify as a regulated investment company for one or more years. In this event, the Fund’s Board of Trustees may authorize a significant change in investment strategy or Fund liquidation. The Fund also may incur transaction and other costs to comply with any new or additional guidance from the Internal Revenue Service.

Commodity-Linked Notes Risk. The Fund's investments in commodity-linked notes may involve substantial risks, including risk of loss of a significant portion of their principal value. In addition to risks associated with the underlying commodities, they may be subject to additional special risks, such as the lack of a secondary trading market and temporary price distortions due to speculators and/or the continuous rolling over of futures contracts underlying the notes. Commodity-linked notes are also subject to counterparty risk, which is the risk that the other party to the contract will not fulfill its contractual obligation to complete the transaction with the Fund.

Commodity Risk. The Fund will concentrate its investments in commodities markets. The Fund’s significant investment exposure to the commodities markets, and/or a particular sector of the commodities markets, which may subject the Fund to greater volatility than investments in traditional securities, such as stocks and bonds. The commodities markets may fluctuate widely based on a variety of factors, including changes in overall market movements, domestic and foreign political and economic events and policies, war, acts of terrorism, changes in domestic or foreign interest rates and/or investor expectations concerning interest rates, domestic and foreign inflation rates and investment and trading activities of mutual funds, hedge funds and commodities funds. Prices of various commodities may also be affected by factors such as drought, floods, weather, livestock disease, embargoes, tariffs and other regulatory developments. The prices of commodities can also fluctuate widely due to supply and demand disruptions in major producing or consuming regions. Because the Fund’s performance is linked to the performance of potentially volatile commodities, investors should be willing to assume the risks of potentially significant fluctuations in the value of the Fund’s shares.

Correlation Risk. Changes in the value of two investments or asset classes may not track or offset each other in the manner anticipated by the portfolio managers. Because the Fund’s investment strategy seeks to balance risk across the four sectors of the commodities markets and, within each commodity sector, to balance risk across different commodities, to the extent either the four sectors of the commodities markets or the selected commodities are correlated in a way not anticipated by the portfolio managers the Fund’s risk allocation process may not succeed in achieving its investment objective.

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

Derivatives Risk. The value of a derivative instrument depends largely on (and is derived from) the value of an underlying security, currency, commodity, interest rate, index or other asset (each referred to as an underlying asset). In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage and liquidity risks. Counterparty risk is the risk that

the counterparty to the derivative contract will default on its obligation to pay the Fund the amount owed or otherwise perform under the derivative contract. Derivatives create leverage risk because they do not require payment up front equal to the economic exposure created by owning the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be harder to value, less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. Also, derivatives used for hedging or to gain or limit exposure to a particular market segment may not provide the expected benefits, particularly during adverse market conditions. These risks are greater for the Fund than most other mutual funds because the Fund will implement its investment strategy primarily through derivative instruments rather than direct investments in stocks and bonds.

Exchange-Traded Funds Risk. An investment by the Fund in exchange-traded funds generally presents the same primary risks as an investment in a mutual fund. In addition, an exchange-traded fund may be subject to the following: (1) a discount of the exchange-traded fund’s shares to its net asset value; (2) failure to develop an active trading market for the exchange-traded fund’s shares; (3) the listing exchange halting trading of the exchange-traded fund’s shares; (4) failure of the exchange-traded fund’s shares to track the referenced asset; and (5) holding troubled securities in the referenced index or basket of investments. Exchange-traded funds may involve duplication of management fees and certain other expenses, as the Fund indirectly bears its proportionate share of any expenses paid by the exchange-traded funds in which it invests. Further, certain of the exchange-traded funds in which the Fund may invest are leveraged. The more the Fund invests in such leveraged exchange-traded funds, the more this leverage will magnify any losses on those investments.

Exchange-Traded Notes Risk. Exchange-traded notes are subject to credit risk, including the credit risk of the issuer, and the value of the exchange-traded note may drop due to a downgrade in the issuer’s credit rating, despite the underlying market benchmark or strategy remaining unchanged. The value of an exchange-traded note may also be influenced by time to maturity, level of supply and demand for the exchange-traded note, volatility and lack of liquidity in the underlying market, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events that affect the referenced underlying market or strategy. Exchange-traded notes are also subject to the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund.

Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. This risk may be magnified due to the Fund's use of derivatives that provide leveraged exposure to government bonds.

Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. The Fund's significant use of derivative instruments may cause liquidity risk to be greater than other mutual funds that invest in more traditional assets such as stocks and bonds, which trade on markets with more market participants.

Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. Because the Fund's investment process relies heavily on its asset allocation process, market movements that are counter to the portfolio managers’ expectations may have a significant adverse effect on the Fund's net asset value. Further,

the portfolio managers’ use of short derivative positions and instruments that provide economic leverage increases the volatility of the Fund's net asset value, which increases the potential of greater losses that may cause the Fund to liquidate positions when it may not be advantageous to do so.

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

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

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

Volatility Risk. The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund's net asset value per share to experience significant increases or declines in value over short periods of time.
