Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 85% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund's investment adviser, Invesco Advisers, Inc. (the Adviser), seeks to achieve the Fund's investment objective by investing primarily in a portfolio of common stocks and other equity securities of value companies across the capitalization spectrum. The Fund emphasizes a value style of investing and the Adviser seeks well-established, undervalued companies believed by the Adviser to possess the potential for capital growth and income. Portfolio securities are typically sold when the assessments of the Adviser of the capital growth and income potential of such securities materially change. The Fund may invest in companies of any size.

The Fund may also invest up to 25% of its total assets in foreign securities.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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:

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

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

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

Value Investing Style Risk. The Fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 62% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund's target allocation is to invest approximately 64% of its total assets in underlying funds that invest primarily in fixed-income securities, approximately 27% of its total assets in underlying funds that invest primarily in equity securities and approximately 9% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund's direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund's portfolio.

Approximately 13% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 3% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund's portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund's asset class allocations, underlying funds and target weightings.

Based on the portfolio managers' research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund's investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund's asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund's target allocation is to invest approximately 64% of its total assets in underlying funds that invest primarily in fixed-income securities, approximately 27% of its total assets in underlying funds that invest primarily in equity securities and approximately 9% of its total assets in alternative asset classes and investment strategies which may include commodities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund's performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund's and the Subsidiary'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 underlying fund's shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund's foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

Foreign Securities Risk. An underlying fund's foreign investments may be affected by changes in a foreign country's exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Repurchase Agreement Risk. If the seller of a repurchase agreement in which an underlying fund invests defaults on its obligation or declares bankruptcy, the underlying fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.
Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.
Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution 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.

Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 62% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 64% of its total assets in underlying funds that invest primarily in fixed-income securities, approximately 27% of its total assets in underlying funds that invest primarily in equity securities and approximately 9% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 13% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 3% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Repurchase Agreement Risk. If the seller of a repurchase agreement in which an underlying fund invests defaults on its obligation or declares bankruptcy, the underlying fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Repurchase Agreement Risk. If the seller of a repurchase agreement in which an underlying fund invests defaults on its obligation or declares bankruptcy, the underlying fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.
Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.
Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution 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.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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. The portfolio turnover rate of the Morgan Stanley Convertible Securities Trust (the predecessor fund) and the Fund for the fiscal year October 1, 2009 to September 30, 2010 was 85% of the average value of the portfolio. The portfolio turnover rate of the Fund for the fiscal period October 1, 2010 to December 31, 2010 was 24% of the average value of the portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 24.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in convertible securities. A convertible security is a bond, preferred stock or other security that may be converted into a prescribed amount of common stock at a prestated price. Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, may retain that common stock to permit its orderly sale or to establish long-term holding periods for tax purposes. The Fund is not required to sell the common stock to assure that the required percentage of its assets is invested in convertible securities. The Fund’s convertible securities may include lower rated fixed-income securities commonly known as junk bonds. The convertible securities also may include exchangeable and synthetic convertible securities. Unlike traditional convertible securities whose conversion values are based on the common stock of the issuer of the convertible security, synthetic and exchangeable convertible securities are preferred stocks or debt obligations of an issuer which are combined with an equity component whose conversion value is based on the value of the common stock of a different issuer or a particular benchmark (which may include a foreign issuer or basket of foreign stocks, or a company whose stock is not yet publicly traded). In deciding which securities to buy, hold or sell, the Adviser considers market, economic and political conditions. The Adviser sells a security when it believes that it no longer fits the Fund’s investment criteria.

The remaining 20% of the Fund’s assets may be invested in common stocks directly, non-convertible preferred stock, non-convertible fixed-income securities and foreign securities (including depositary receipts). The Fund’s fixed-income investments may include zero coupon securities, which are purchased at a discount and generally accrue interest, but make no payment until maturity.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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

Convertible Securities. The values of convertible securities in which the Fund may invest may be affected by market interest rates. The values of convertible securities also may be affected by the risk of actual issuer default on interest or principal payments and the value of the underlying stock. Additionally, an issuer may retain the right to buy back its convertible securities at a time and price unfavorable to the Fund. The value of a synthetic convertible security will respond differently to market fluctuations than a convertible security because a synthetic convertible security is composed of two or more separate securities, each with its own market value.

Fixed-Income Securities. All fixed-income securities are subject to two types of risk: credit risk and interest rate risk. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Lower rated fixed-income securities (commonly known as junk bonds) are subject to greater risk of loss of income and principal than higher-rated securities. The prices of junk bonds are likely to be more sensitive to adverse economic changes or individual corporate developments and may be subject to a greater risk of default than higher-rated securities. During an economic downturn or substantial period of rising interest rates, junk bond issuers and, in particular, highly leveraged issuers may experience financial stress.

Common Stocks and Other Equity Securities. In general, stock and other equity securities values fluctuate in response to activities specific to the company as well as general market, economic and political conditions.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s performance to that of a broad/style-based securities market benchmark and a peer group benchmark with investment objectives and strategies similar to those of the Fund. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of its future performance.

The returns for periods prior to June 1, 2010 are those of the Class A, Class B, Class C and Class I Shares of the predecessor fund. The predecessor fund was advised by Morgan Stanley Investment Advisors Inc. Class A, Class B, Class C and Class I shares of the predecessor fund were reorganized into Class A, Class B, Class C and Class Y shares, respectively, of the Fund on June 1, 2010. Class A, Class B, Class C and Class Y shares’ returns of the Fund will be different from the predecessor fund as they have different expenses. Predecessor fund performance for Class A and Class B shares has been restated to reflect the Fund’s applicable sales charge. Performance for Class B shares assumes conversion to Class A shares eight years after the start of the performance period. Year-to-date returns include returns of the Fund for periods ending on and after June 1, 2010.

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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 74% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 74.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests, under normal circumstances, at least 80% of net assets (plus borrowings for investment purposes) in equity securities.

In complying with the 80% investment requirement, the Fund may include synthetic instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement. These derivatives and other investments may have the effect of leveraging the Fund's portfolio.

The Fund invests, under normal circumstances, in issuers located in at least three different countries, including the U.S.

The Fund emphasizes investment in issuers in the U.S. and in the developed countries of Western Europe and in the Pacific Basin. The Fund may also invest up to 20% of its total assets in issuers located in developing countries, i.e., those that are in the initial stages of their industrial cycles. As of December 31, 2010, the principal countries in which the Fund was invested were the United States, Japan, the United Kingdom, Canada, Sweden and Australia.

The portfolio managers will consider selling or reducing a security position (i) if the forecasted return of a security becomes less attractive relative to industry peers or (ii) if a particular security's risk profile changes.

The portfolio managers use quantitative, research based models to select potential investment securities. They then use proprietary and non-proprietary models to forecast risks and transaction costs. This information is used to structure the Fund's portfolio. When building the portfolio, the portfolio managers consider the securities of the MSCI World Index as well as securities that are not included in the MSCI World Index. They then apply a quantitative stock selection model to the securities to create a return/risk forecast prior to constructing the portfolio.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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:

Currency/Exchange Rate Risk. The dollar value of the Fund's foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

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

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

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.

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

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

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

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

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.

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

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

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 the same.

Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 73% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 73.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they both are indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 71% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 7% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 22% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 28.4% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 6% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.

Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund’s target allocation is to invest approximately 71% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 7% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 22% of its total assets in alternative asset classes and investment strategies which may include commodities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.

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

Independent Management of Sector Risk. Underlying funds may invest in different, independently-managed sectors. Accordingly, poor performance of an investment in one sector may have a significant effect on an underlying fund’s net asset value. Additionally, active rebalancing of an underlying fund’s investments among the sectors may result in increased transaction costs. Independent management of sectors may also result in adverse tax consequences when one or more of an underlying fund’s portfolio managers effect transactions in the same security at or about the same time.

Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Sector Fund Risk. Certain of the underlying fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the underlying fund more volatile.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.
Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution 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.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they both are indirect wholly-owned subsidiaries of Invesco Ltd. The Fund's target allocation is to invest approximately 71% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 7% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 22% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund's direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund's portfolio.

Approximately 28.4% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 6% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund's portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund's asset class allocations, underlying funds and target weightings.

Based on the portfolio managers' research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund's investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund's asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund's target allocation is to invest approximately 71% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 7% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 22% of its total assets in alternative asset classes and investment strategies which may include commodities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund's performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund's and the Subsidiary'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 underlying fund's shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund's foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

Foreign Securities Risk. An underlying fund's foreign investments may be affected by changes in a foreign country's exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

Fund of Funds Risk. The Fund's performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.

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

Independent Management of Sector Risk. Underlying funds may invest in different, independently-managed sectors. Accordingly, poor performance of an investment in one sector may have a significant effect on an underlying fund's net asset value. Additionally, active rebalancing of an underlying fund's investments among the sectors may result in increased transaction costs. Independent management of sectors may also result in adverse tax consequences when one or more of an underlying fund's portfolio managers effect transactions in the same security at or about the same time.

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds' 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower's payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling.

Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund's return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund's securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund's portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer's ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund's potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund's yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund's holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Sector Fund Risk. Certain of the underlying fund's investments are concentrated in a comparatively narrow segment of the economy, which may make the underlying fund more volatile.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund's exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary's investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund's ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a "fund of funds," and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they both are indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 71% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 7% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 22% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 28.4% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 6% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.

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

Independent Management of Sector Risk. Underlying funds may invest in different, independently-managed sectors. Accordingly, poor performance of an investment in one sector may have a significant effect on an underlying fund’s net asset value. Additionally, active rebalancing of an underlying fund’s investments among the sectors may result in increased transaction costs. Independent management of sectors may also result in adverse tax consequences when one or more of an underlying fund’s portfolio managers effect transactions in the same security at or about the same time.

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Sector Fund Risk. Certain of the underlying fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the underlying fund more volatile.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market.

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 the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 16% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 16.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser). The Fund invests its assets in a selection of underlying funds which invest primarily in international or domestic equities, fixed-income securities or real estate investment trusts. The Fund’s target allocation is to invest 65% of its total assets in underlying funds that invest primarily in fixed-income securities and 35% of its total assets in underlying funds that invest primarily in equity securities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, exchange-traded funds (ETF) and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager balances the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

The Adviser rebalances the Fund’s investments in the underlying funds on an annual basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund’s target allocation is to invest 65% of its total assets in underlying funds that invest primarily in fixed-income securities and 35% of its total assets in underlying funds that invest primarily in equity securities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Credit Risk. The issuer of instruments in which an underlying 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. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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

Industry Focus Risk. To the extent an underlying fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the underlying fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing; changes in government regulation and interest rates; and overall economy.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Reverse Repurchase Agreement Risk. Reverse repurchase agreements involve the risk that the market value of securities to be repurchased may decline below the repurchase price or that the other party may default on its obligation, resulting in delays, additional costs or the restriction of proceeds from the sale.

Sector Fund Risk. Certain of the underlying fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the underlying fund more volatile.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Utilities Sector Risk. The following factors may affect an underlying fund’s investments in the utilities sector: governmental regulation, economic factors, ability of the issuer to obtain financing, prices of natural resources and risks associated with nuclear power.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser). The Fund invests its assets in a selection of underlying funds which invest primarily in international or domestic equities, fixed-income securities or real estate investment trusts. The Fund’s target allocation is to invest 65% of its total assets in underlying funds that invest primarily in fixed-income securities and 35% of its total assets in underlying funds that invest primarily in equity securities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, exchange-traded funds (ETF) and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager balances the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

The Adviser rebalances the Fund’s investments in the underlying funds on an annual basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund’s target allocation is to invest 65% of its total assets in underlying funds that invest primarily in fixed-income securities and 35% of its total assets in underlying funds that invest primarily in equity securities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Credit Risk. The issuer of instruments in which an underlying 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. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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

Industry Focus Risk. To the extent an underlying fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the underlying fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing; changes in government regulation and interest rates; and overall economy.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Reverse Repurchase Agreement Risk. Reverse repurchase agreements involve the risk that the market value of securities to be repurchased may decline below the repurchase price or that the other party may default on its obligation, resulting in delays, additional costs or the restriction of proceeds from the sale.

Sector Fund Risk. Certain of the underlying fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the underlying fund more volatile.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Utilities Sector Risk. The following factors may affect an underlying fund’s investments in the utilities sector: governmental regulation, economic factors, ability of the issuer to obtain financing, prices of natural resources and risks associated with nuclear power.

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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 6% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund invests its assets in a selection of underlying funds that invest primarily in global or international securities. The underlying funds may invest a portion of their assets in securities of domestic issuers. The Fund’s target allocation is to invest 100% of its total assets in underlying funds that invest primarily in equity securities. A portion of the underlying fund’s assets may be invested in fixed-income securities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, exchange-traded funds (ETF) and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager balances the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

The Adviser rebalances the Fund’s investments in the underlying funds on an annual basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund’s target allocation is to invest 100% of its total assets in underlying funds that invest primarily in equity securities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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

Initial Public Offerings (IPO) Risk. The prices of IPO securities fluctuate more than prices of equity securities of companies with longer trading histories. In addition, companies offering securities in IPOs may have less experienced management or limited operating histories. There can be no assurance that the underlying fund will have favorable IPO investment opportunities.

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.

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 6% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund invests its assets in a selection of underlying funds that invest primarily in global or international securities. The underlying funds may invest a portion of their assets in securities of domestic issuers. The Fund’s target allocation is to invest 100% of its total assets in underlying funds that invest primarily in equity securities. A portion of the underlying fund’s assets may be invested in fixed-income securities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, exchange-traded funds (ETF) and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager balances the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

The Adviser rebalances the Fund’s investments in the underlying funds on an annual basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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

Initial Public Offerings (IPO) Risk. The prices of IPO securities fluctuate more than prices of equity securities of companies with longer trading histories. In addition, companies offering securities in IPOs may have less experienced management or limited operating histories. There can be no assurance that the underlying fund will have favorable IPO investment opportunities.

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.

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

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 the same.

Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 61% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 61.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests, under normal circumstances, at least 80% of net assets (plus borrowings for investment purposes) in equity securities of mid-capitalization companies. In complying with the 80% investment requirement, the Fund may include synthetic instruments that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement. These derivatives and other investments may have the effect of leveraging the Fund’s portfolio.

The portfolio management team seeks to construct a portfolio of issuers that have high or improving return on invested capital (ROIC), quality management, a strong competitive position and which are trading at compelling valuations.

The Fund considers a company to be a mid-capitalization company if it has a market capitalization, at the time of purchase, within the range of the largest and smallest capitalized companies included in the Russell Midcap® Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month. As of January 31, 2011, the capitalization of companies in the Russell Midcap® Index range from $228 million to $21.2 billion.

The Fund may invest up to 25% of its total assets in foreign securities.

In selecting securities for the Fund, the portfolio managers conduct fundamental research of issuers to gain a thorough understanding of their business prospects, appreciation potential and return on invested capital. The process they use to identify potential investments for the Fund includes three phases: financial analysis, business analysis and valuation analysis. The portfolio managers will generally invest in an issuer when they have determined it potentially has high or improving ROIC, quality management, a strong competitive position and is trading at an attractive valuation.

The portfolio managers consider selling a security when it exceeds the target price, has not shown a demonstrable improvement in fundamentals or a more compelling investment opportunity exists.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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:

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

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.

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

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

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.

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

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

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

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

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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 69% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 52% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 30% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 17% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 23% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 5% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting of the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund’s target allocation is to invest approximately 52% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 30% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 17% of its total assets in alternative asset classes and investment strategies which may include commodities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 52% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 30% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 17% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 23% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 5% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting of the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund’s target allocation is to invest approximately 52% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 30% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 17% of its total assets in alternative asset classes and investment strategies which may include commodities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 69% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 52% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 30% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 17% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 23% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 5% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting of the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 68% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 62% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 17% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 21% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 26.2% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 6% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund’s target allocation is to invest approximately 62% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 17% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 21% of its total assets in alternative asset classes and investment strategies which may include commodities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 62% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 17% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 21% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 26.2% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 6% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 70% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 32% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 54% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 13% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 16% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 4% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund’s target allocation is to invest approximately 32% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 54% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 13% of its total assets in alternative asset classes and investment strategies which may include commodities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 32% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 54% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 13% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 16% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 4% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco and/or the Adviser) and exchange-traded funds (ETFs) advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 32% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 54% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 13% of its total assets in alternative asset classes and investment strategies which may include commodities.

The underlying funds may also invest in investments with economic characteristics similar to an underlying fund’s direct investments, including derivatives, ETFs and American Depositary Receipts. These derivatives and other investments may have the effect of leveraging an underlying fund’s portfolio.

Approximately 16% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 4% of the assets that are invested in alternative classes will be allocated to underlying funds that invest primarily in commodities.

In attempting to meet its investment objective, an underlying fund engages in active and frequent trading of portfolio securities.

The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the manager attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of a Fund’s asset class allocations, underlying funds and target weightings.

Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well in any given period and protect during periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on a quarterly basis to keep them within their target weightings and has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without shareholder approval.

The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated ETFs. An ETF is a security that tracks an index, a commodity or a basket of assets, but trades like a stock on an exchange. ETFs experience price changes throughout the day as they are bought and sold.

Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund’s target allocation is to invest approximately 32% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 54% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 13% of its total assets in alternative asset classes and investment strategies which may include commodities.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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 risk of investing in the Fund is that the Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time. The principal risks of investing in the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value and yield of the securities retained by the underlying fund may decline below the price of the mortgage-related securities sold by the underlying fund that it is obligated to repurchase.

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

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Futures Risk. A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

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

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.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying ETFs.

Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain underlying ETFs, and incurs costs in buying and selling securities, especially when rebalancing the underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of the Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Prepayment Risk. An issuer’s ability to prepay principal on a loan or debt security prior to maturity can limit an underlying fund’s potential gains. Prepayments may require the underlying fund to replace the loan or debt security with a lower yielding security, adversely affecting an underlying fund’s yield.

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

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Replication Management Risk. Unlike many investment companies, certain of the underlying funds are not “actively” managed. That is, an underlying fund does not utilize an investing strategy that seeks returns in excess of the underlying index of certain underlying ETFs. Therefore, it would not necessarily sell a security unless that security is removed from the underlying index of certain underlying ETFs.

Short Sales Risk. Short sales may cause an underlying fund to repurchase a security at a higher price, causing a loss. As there is no limit on how much the price of the security can increase, an underlying fund’s exposure is unlimited.

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Swaps Risk. A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, currencies or other instruments. Swaps are subject to credit risk and counterparty risk.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Value Investing Style Risk. The underlying fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

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 the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 38% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 38.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests, under normal circumstances, at least 80% of net assets (plus borrowings for investment purposes) in securities of small-capitalization issuers. In complying with the 80% investment requirement, the Fund may include synthetic instruments that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement. The Fund invests primarily in equity securities of issuers that are considered by the Fund’s portfolio managers to have strong earnings growth.

The Fund considers an issuer to be a small-capitalization issuer if it has a market capitalization, at the time of purchase, no larger than the largest capitalized issuer included in the Russell 2000® Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month. As of January 31, 2011, the capitalization of companies in the Russell 2000® Index range from $15 million to $4.5 billion.

The Fund may also invest up to 25% of its total assets in foreign securities.

In selecting investments, the portfolio managers utilize a disciplined portfolio construction process that diversifies the Fund based on the industry group diversification of the Russell 2000® Growth Index and generally maintains a maximum deviation from index industry groups of 350 basis points. The security selection process is based on a three-step process that includes fundamental, valuation and timeliness analysis focused on identifying high quality, fundamentally sound issuers operating in an attractive industry; attractively valued securities given their growth potential over a one- to two-year horizon; and the “timeliness” of a purchase, respectively. The timeliness analysis includes a review of relative price strength, trading volume characteristics and trend analysis to look for signs of deterioration. If a stock shows signs of deterioration, it is generally not considered it as a candidate for the portfolio.

The portfolio managers consider selling a security if a change in industry or issuer fundamentals indicates a problem, the price target set at purchase is exceeded or a change in technical outlook indicates poor relative strength.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund invests, under normal circumstances, at least 80% of net assets (plus borrowings for investment purposes) in securities of small-capitalization issuers. In complying with the 80% investment requirement, the Fund may include synthetic instruments that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement. The Fund invests primarily in equity securities of issuers that are considered by the Fund’s portfolio managers to have strong earnings growth.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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:

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.

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

Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.

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.

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

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

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default.
Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.

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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 38% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 38.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests, under normal circumstances, at least 80% of net assets (plus borrowings for investment purposes) in securities of small-capitalization issuers. In complying with the 80% investment requirement, the Fund may include synthetic instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement. The Fund invests primarily in equity securities of issuers that are considered by the Fund's portfolio managers to have strong earnings growth.

The Fund considers an issuer to be a small-capitalization issuer if it has a market capitalization, at the time of purchase, no larger than the largest capitalized issuer included in the Russell 2000® Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month. As of January 31, 2011, the capitalization of companies in the Russell 2000® Index range from $15 million to $4.5 billion.

The Fund may also invest up to 25% of its total assets in foreign securities.

In selecting investments, the portfolio managers utilize a disciplined portfolio construction process that diversifies the Fund based on the industry group diversification of the Russell 2000® Growth Index and generally maintains a maximum deviation from index industry groups of 350 basis points. The security selection process is based on a three-step process that includes fundamental, valuation and timeliness analysis focused on identifying high quality, fundamentally sound issuers operating in an attractive industry; attractively valued securities given their growth potential over a one- to two-year horizon; and the “timeliness” of a purchase, respectively. The timeliness analysis includes a review of relative price strength, trading volume characteristics and trend analysis to look for signs of deterioration. If a stock shows signs of deterioration, it is generally not considered it as a candidate for the portfolio.

The portfolio managers consider selling a security if a change in industry or issuer fundamentals indicates a problem, the price target set at purchase is exceeded or a change in technical outlook indicates poor relative strength.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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:

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.

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

Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.

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.

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

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

Small- and Mid-Capitalization Risks. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect the Fund's ability to recover should they default.
Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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. The portfolio turnover rate of the Van Kampen Harbor Fund (the predecessor fund) and the Fund for the most recent fiscal year was 91% of the average value of the portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 91.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing principally in a portfolio of debt securities, primarily convertible bonds and convertible preferred stocks. Under normal market conditions, the Fund invests at least 50% of its total assets (excluding cash, cash equivalents and government securities) in convertible debt securities. The Fund may invest without limitations as to credit ratings, and such investments may include high- medium- and lower-rated and unrated securities. Through careful selection of individual securities, diversification of investments and by continuing supervision of the investment portfolio, Invesco Advisers, Inc. (the Adviser) seeks to provide income and capital appreciation while striving to reduce risk and conserve shareholder capital. The Adviser emphasizes income-producing securities of companies whose common stocks are believed to have good prospects for capital appreciation and seek to identify companies with improving fundamentals, strong earnings growth, increasing market share and attractive valuations that are likely to provide investors with equity participation through the issuance of convertible securities. The Fund generally sells securities when the Adviser determines that such securities no longer meet its investment criteria.

The Fund may invest up to 45% of its total assets in common stocks and up to 25% of its total assets in securities of foreign issuers. The Fund may purchase and sell options, futures contracts and options on futures contracts, which are derivatives, for various portfolio management purposes, including to earn income, to facilitate portfolio management and to mitigate risks. In general terms, a derivative instrument is one whose value depends on (or is derived from) the value of an underlying asset, interest rate or index.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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

Market Risk. Market risk is the possibility that the market values of securities owned by the Fund will decline. Investments in common stocks and other equity securities generally are affected by changes in the stock markets, which fluctuate substantially over time, sometimes suddenly and sharply. Investments in debt securities generally are affected by changes in interest rates and the creditworthiness of the issuer. The prices of such securities tend to fall as interest rates rise, and such declines tend to be greater among debt securities with longer maturities. The value of a convertible security tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying equity security.

Credit Risk. Credit risk refers to an issuer's ability to make timely payments of interest and principal. Because the Fund may invest in securities with low credit quality, it is subject to a higher level of credit risk than a fund that invests only in investment grade securities. The credit quality of noninvestment grade securities is considered speculative by recognized rating agencies with respect to the issuer's continuing ability to pay interest and principal. Lower-grade securities (also sometimes known as junk bonds) may have less liquidity and a higher incidence of default than investments in higher-grade securities. The Fund may incur higher expenses to protect the Fund's interest in such securities. The credit risks and market prices of lower-grade securities generally are more sensitive to negative corporate developments, such as a decline in profits, or adverse economic conditions, such as a recession, than are higher-grade securities.

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

Income Risk. The interest income on debt securities, including convertible bonds, generally is affected by prevailing interest rates, which can vary widely over the short- and long-term. The ability of equity securities to generate income generally depends on the earnings and continuing declaration of dividends by the issuers of such securities. If interest rates drop or dividends are reduced or discontinued, distributions to shareholders from the Fund may drop as well.

Foreign Risks. Because the Fund may own securities of foreign issuers, it may be subject to risks that can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in financial reporting, differences in securities regulation and trading, and foreign taxation issues. The Fund may also invest in issuers in developing or emerging market countries, which are subject to greater risks than investments in securities of issuers in developed countries.

Risks of Derivatives. A derivative instrument often has risks similar to its underlying instrument and may have additional risks, including imperfect correlation between the value of the derivative and the underlying instrument, risks of default by the other party to certain transactions, magnification of losses incurred due to changes in the market value of the securities, instruments, indices or interest rates to which they relate, and risks that the transactions may not be liquid. Certain derivative transactions may give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss.

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund's performance to that of a broad-based securities/style specific market benchmark and a peer group benchmark comprised of funds with investment objectives and strategies similar to the Fund. The Fund's (and the predecessor fund's) past performance (before and after taxes) is not necessarily an indication of its future performance.

The returns for periods prior to June 1, 2010 are those of the Class A, Class B, Class C and Class I Shares of the predecessor fund. The predecessor fund was advised by Van Kampen Asset Management. Class A, Class B, Class C and Class I shares of the predecessor fund were reorganized into Class A, Class B, Class C and Class Y shares, respectively, of the Fund on June 1, 2010. Class A, Class B, Class C and Class Y shares' returns of the Fund will be different from the predecessor fund as they have different expenses. Performance for Class A and Class B shares has been restated to reflect the Fund's applicable sales charge. Year-to-date returns include returns of the Fund for periods ending on or after June 1, 2010.

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

Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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. The portfolio turnover rate of the Van Kampen Leaders Fund (the predecessor fund) and the Fund for the fiscal year April 1, 2009 to March 31, 2010 was 9% of the average value of the portfolio. The portfolio turnover rate of the Fund for the fiscal period April 1, 2010 to December 31, 2010 was 4% of the average value of portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The Fund seeks to achieve its investment objectives by investing primarily in a combination of certain Invesco Van Kampen funds (the Underlying Funds) on a fixed percentage allocation basis. The Underlying Funds invest in U.S. and foreign equity securities, fixed income, money market securities and derivatives. The Fund makes equal allocations of its assets to the following three Underlying Funds: Invesco Van Kampen Comstock Fund (Comstock Fund), Invesco Van Kampen Equity and Income Fund (Equity and Income Fund) and Invesco Van Kampen International Growth Fund (International Growth Fund). The investment results of the Underlying Funds will vary. As a result, the percentage allocations to the Underlying Funds will be monitored daily by Invesco Advisers, Inc. (the Adviser), the Fund’s and the Underlying Funds’ investment adviser, and the Fund’s allocations to the Underlying Funds will be rebalanced whenever the actual allocations exceed plus or minus 5% of the pre-determined fixed percentage allocation basis.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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

Risks of Investing in the Underlying Funds. Each of the Underlying Funds in which the Fund invests has its own investment risks, and those risks can affect the value of the Underlying Funds’ shares and therefore the value of the Fund’s investments. In addition, there is no guarantee that the Underlying Funds will achieve each of their investment objectives or that the Underlying Funds will not change their investment objectives without the approval of the Fund. In addition, the Fund will bear its pro rata portion of the expenses of the Underlying Funds. In selecting among the Underlying Funds (which also advised by the Adviser), the Adviser is subject to the potential conflict of interest presented because the fees paid by some Underlying Funds to the Adviser are higher than the fees paid by other Underlying Funds.

Non-Diversified Fund. A non-diversified fund generally is subject to greater risk than a diversified fund because changes in the financial condition or market assessment of a single issuer may cause greater fluctuations in the value of such non-diversified funds’ shares.

Risks of Investing in the Underlying Funds

Market Risk. Market risk is the possibility that the market values of securities owned by the Underlying Fund will decline. Investment in common stocks and other equity securities generally are affected by changes in the stock markets, which fluctuate substantially over time, sometimes suddenly and sharply. Investments in debt securities generally are affected by changes in interest rates and the creditworthiness of the issuer. The prices of such securities tend to fall as interest rates rise, and such declines tend to be greater among securities with longer maturities. The value of a convertible security tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying equity security.

Small- and Medium-Sized Companies Risk. During an overall stock market decline, stock prices of small- or medium-sized companies (in which the Underlying Funds may invest) often fluctuate more than stock prices of larger companies.

Income Risk. The ability of the Underlying Funds’ equity securities to generate income generally depends on the earnings and the continuing declaration of dividends by the issuers of such securities. The interest income on the Underlying Funds’ debt securities generally is affected by prevailing interest rates, which can vary widely over the short-and long-term.

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

Credit Risk. Credit risk refers to an issuer’s ability to make timely payments of interest and principal. Because an Underlying Fund generally invests only in investment grade-quality debt securities, it is subject to a lower level of credit risk than a fund investing in lower-quality securities. Securities rated BBB by Standard & Poor’s (S&P) or Baa by Moody’s Investor Service, Inc. (Moody’s) are in the lowest of the four investment grades and are considered by the rating agencies to be medium-grade obligations, which possess speculative characteristics so that changes in economic conditions or other circumstances are more likely to lead to a weakened capacity of the issuer to make principal and interest payments than in the case of higher-rated securities.

Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in securities regulation and trading, and foreign taxation issues.

Risks of Investing in REITs. Investing in REITs makes the Underlying Funds more susceptible to risks associated with the ownership of real estate and with the real estate industry in general and may involve duplication of management fees and other expenses. REITs may be less diversified than other pools of securities, may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets.

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

Style-Specific Investing. A value style of investing (used by the Comstock Fund and the Equity and Income Fund) emphasizes undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value securities are less than returns on other styles of investing or the overall market.

A growth style of investing (used by the International Growth Fund) emphasizes companies with growth characteristics. The market values of growth securities may be more volatile than those of other types of investments. The returns on growth securities may or may not move in tandem with the returns on other styles of investing or the overall stock markets.

Market Risk. Market risk is the possibility that the market values of securities owned by the Underlying Fund will decline. Investment in common stocks and other equity securities generally are affected by changes in the stock markets, which fluctuate substantially over time, sometimes suddenly and sharply. Investments in debt securities generally are affected by changes in interest rates and the creditworthiness of the issuer. The prices of such securities tend to fall as interest rates rise, and such declines tend to be greater among securities with longer maturities. The value of a convertible security tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying equity security.

Small- and Medium-Sized Companies Risk. During an overall stock market decline, stock prices of small- or medium-sized companies (in which the Underlying Funds may invest) often fluctuate more than stock prices of larger companies.

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s performance to that of a broad-based securities market benchmark and style specific benchmark. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of its future performance.

The returns for periods prior to June 1, 2010 are those of the Class A, Class B, Class C and Class I shares of the predecessor fund. The predecessor fund was advised by Van Kampen Asset Management. Class A, Class B, Class C and Class I shares of the predecessor fund were reorganized into Class A, Class B, Class C and Class Y shares, respectively, of the Fund on June 1, 2010. Class A, Class B, Class C and Class Y shares’ returns of the Fund will be different from the predecessor fund as they have different expenses. Performance for Class A and Class B shares has been restated to reflect the Fund’s applicable sales charge. Year-to-date returns include returns of the Fund for periods ending on and after June 1, 2010.

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

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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. The portfolio turnover rate of the Van Kampen Real Estate Securities Fund (the predecessor fund) and the Fund for the most recent fiscal year was 86% of the average value of the portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objectives by investing primarily in a portfolio of securities of companies operating in the real estate industry, including equity securities of real estate investment trusts (REITs) and other securities of real estate operating companies. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies operating in the real estate industry, including equity securities of REITs and other securities of real estate operating companies at the time of investment. A company operating in the real estate industry is one that derives at least 50% of its assets, gross income or net profits from the ownership, construction, management or sale of residential, commercial or industrial real estate. Besides equity securities of REITs, the Fund may invest in equity securities, including common stocks and convertible securities, or non-convertible preferred stocks and investment-grade debt securities of companies operating in the real estate industry. The Fund may invest up to 20% of the Fund’s net assets in securities of companies outside the real estate industry. The Fund may invest up to 25% of its total assets in securities of foreign issuers, some or all of which may be in the real estate industry. The Fund may purchase and sell options, futures contracts and options on futures contracts, which are derivative instruments, for various portfolio management purposes, including to earn income, to facilitate portfolio management and to mitigate risks. In general terms, a derivative instrument is one whose value depends on (or is derived from) the value of an underlying asset, interest rate or index.

When constructing the portfolio, the portfolio managers use a fundamentals driven investment process, including an evaluation of factors such as real property market cycle analysis, real property evaluation and management and structure review to identify securities with characteristics including (i) quality underlying properties, (ii) solid management teams with the ability to effectively manage capital structure decisions, and (iii) attractive valuations relative to peer investment alternatives.

The portfolio managers and investment team focus on equity REITs and real estate operating issuers. Some of the fundamental factors that are evaluated in screening potential investments for the Fund include: forecasted occupancy and rental rates of the various property markets in which a firm may operate, property locations, physical attributes and cash flow generating capacity of an issuer’s properties and calculating relative return potential, asset quality, management depth and skill, insider ownership, overall debt levels, percentage of variable rate financing and fixed charge coverage ratios. The issuers that are believed to have the most attractive fundamental attributes are then screened according to pricing factors that allow the management team to assess security valuations relative to one another and relative to the investment teams’ assessment of underlying asset value. The portfolio managers also consider the relative liquidity of each security in the construction of the Fund.

The portfolio managers seek to construct a portfolio with risk characteristics similar to the FTSE NAREIT Equity All REITs Index (the benchmark index). The Fund seeks to limit risk through various controls, such as diversifying the portfolio property types and geographic areas as well as by limiting the size of any one holding. Various factors may lead to overweighting or underweighting of particular property types and/or geographic areas from time to time.

The portfolio managers will consider selling a security if they conclude (1) its relative valuation falls below desired levels, (2) its risk/return profile changes significantly, (3) its fundamentals change, or (4) a more attractive investment opportunity is identified.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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

Market Risk. Market risk is the possibility that the market values of securities owned by the Fund will decline. Market risk may affect a single issuer, industry, sector of the economy or the market as a whole. Investments in equity securities generally are affected by changes in the stock markets, which fluctuate substantially over time, sometimes suddenly and sharply. The prices of equity securities of companies in the real estate industry may be more volatile and may not fluctuate in tandem with overall changes in the stock markets. Investments in fixed income or debt securities generally are affected by changes in interest rates and creditworthiness of the issuer. The prices of fixed income or debt securities tend to fall as interest rates rise, and such declines tend to be greater among securities with longer maturities.

Risks of Investing in Real Estate. The risks of investing in real estate can include fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local economic conditions; decreases in market rates for rents; increases in competition, property taxes, capital expenditures, or operating expenses; and other economic, political or regulatory occurrences affecting the real estate industry. In addition, REITs depend upon specialized management skills, may not be diversified, may have less trading volume, and may be subject to more abrupt or erratic price movements than the overall securities markets. REITs must comply with certain requirements of the federal income tax law to maintain their federal income tax status. Some REITs (especially mortgage REITs) are affected by risks similar to those associated with investments in debt securities including changes in interest rates and the quality of credit extended. Investments in REITs may involve duplication of management fees and certain other expenses.

Concentration Risk. Because the Fund concentrates in investments in the real estate industry, the value of your shares may rise and fall more than the value of share of a fund that invests in companies in a broader range of industries.

Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in financial reporting, differences in securities regulation and trading, and foreign taxation issues.

Non-Diversification Risks. The Fund may be subject to greater risk than a diversified fund because changes in the financial condition or market assessment of a single issuer may cause greater fluctuations in the value of the Fund’s shares.

Risks of Using Derivative Instruments. Risks of derivatives include imperfect correlation between the value of the instruments and the underlying assets; risks of default by the other party to certain transactions; risks that the transactions may result in losses that partially or completely offset gains in portfolio positions; and risks that the transactions may not be liquid.
Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.
Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus Non-Diversification Risks. The Fund may be subject to greater risk than a diversified fund because changes in the financial condition or market assessment of a single issuer may cause greater fluctuations in the value of the Fund’s shares.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s performance to that of a broad-based securities market benchmark, a style specific benchmark and a peer group benchmark comprised of funds with investment objectives and strategies similar to the Fund. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of its future performance.

The returns for periods prior to June 1, 2010 are those of the Class A, Class B, Class C and Class I shares of the predecessor fund. The predecessor fund was advised by Van Kampen Asset Management. Class A, Class B, Class C and Class I shares of the predecessor fund were reorganized into Class A, Class B, Class C and Class Y shares, respectively, of the Fund on June 1, 2010. Class A, Class B, Class C and Class Y shares’ returns of the Fund will be different from the predecessor fund as they have different expenses. Performance for Class A and Class B shares has been restated to reflect the Fund’s applicable sales charges. Year-to-date returns include returns of the Fund for periods ending on and after June 1, 2010.

Updated performance information is available on the Fund’s Web site at www.invesco.com/us.

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 the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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. The portfolio turnover rate of the Van Kampen Real Estate Securities Fund (the predecessor fund) and the Fund for the most recent fiscal year was 86% of the average value of the portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objectives by investing primarily in a portfolio of securities of companies operating in the real estate industry, including equity securities of real estate investment trusts (REITs) and other securities of real estate operating companies. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies operating in the real estate industry, including equity securities of REITs and other securities of real estate operating companies at the time of investment. A company operating in the real estate industry is one that derives at least 50% of its assets, gross income or net profits from the ownership, construction, management or sale of residential, commercial or industrial real estate. Besides equity securities of REITs, the Fund may invest in equity securities, including common stocks and convertible securities, or non-convertible preferred stocks and investment-grade debt securities of companies operating in the real estate industry. The Fund may invest up to 20% of the Fund’s net assets in securities of companies outside the real estate industry. The Fund may invest up to 25% of its total assets in securities of foreign issuers, some or all of which may be in the real estate industry. The Fund may purchase and sell options, futures contracts and options on futures contracts, which are derivative instruments, for various portfolio management purposes, including to earn income, to facilitate portfolio management and to mitigate risks. In general terms, a derivative instrument is one whose value depends on (or is derived from) the value of an underlying asset, interest rate or index.

When constructing the portfolio, the portfolio managers use a fundamentals driven investment process, including an evaluation of factors such as real property market cycle analysis, real property evaluation and management and structure review to identify securities with characteristics including (i) quality underlying properties, (ii) solid management teams with the ability to effectively manage capital structure decisions, and (iii) attractive valuations relative to peer investment alternatives.

The portfolio managers and investment team focus on equity REITs and real estate operating issuers. Some of the fundamental factors that are evaluated in screening potential investments for the Fund include: forecasted occupancy and rental rates of the various property markets in which a firm may operate, property locations, physical attributes and cash flow generating capacity of an issuer’s properties and calculating relative return potential, asset quality, management depth and skill, insider ownership, overall debt levels, percentage of variable rate financing and fixed charge coverage ratios. The issuers that are believed to have the most attractive fundamental attributes are then screened according to pricing factors that allow the management team to assess security valuations relative to one another and relative to the investment teams’ assessment of underlying asset value. The portfolio managers also consider the relative liquidity of each security in the construction of the Fund.

The portfolio managers seek to construct a portfolio with risk characteristics similar to the FTSE NAREIT Equity All REITs Index (the benchmark index). The Fund seeks to limit risk through various controls, such as diversifying the portfolio property types and geographic areas as well as by limiting the size of any one holding. Various factors may lead to overweighting or underweighting of particular property types and/or geographic areas from time to time.

The portfolio managers will consider selling a security if they conclude (1) its relative valuation falls below desired levels, (2) its risk/return profile changes significantly, (3) its fundamentals change, or (4) a more attractive investment opportunity is identified.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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

Market Risk. Market risk is the possibility that the market values of securities owned by the Fund will decline. Market risk may affect a single issuer, industry, sector of the economy or the market as a whole. Investments in equity securities generally are affected by changes in the stock markets, which fluctuate substantially over time, sometimes suddenly and sharply. The prices of equity securities of companies in the real estate industry may be more volatile and may not fluctuate in tandem with overall changes in the stock markets. Investments in fixed income or debt securities generally are affected by changes in interest rates and creditworthiness of the issuer. The prices of fixed income or debt securities tend to fall as interest rates rise, and such declines tend to be greater among securities with longer maturities.

Risks of Investing in Real Estate. The risks of investing in real estate can include fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local economic conditions; decreases in market rates for rents; increases in competition, property taxes, capital expenditures, or operating expenses; and other economic, political or regulatory occurrences affecting the real estate industry. In addition, REITs depend upon specialized management skills, may not be diversified, may have less trading volume, and may be subject to more abrupt or erratic price movements than the overall securities markets. REITs must comply with certain requirements of the federal income tax law to maintain their federal income tax status. Some REITs (especially mortgage REITs) are affected by risks similar to those associated with investments in debt securities including changes in interest rates and the quality of credit extended. Investments in REITs may involve duplication of management fees and certain other expenses.

Concentration Risk. Because the Fund concentrates in investments in the real estate industry, the value of your shares may rise and fall more than the value of share of a fund that invests in companies in a broader range of industries.

Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in financial reporting, differences in securities regulation and trading, and foreign taxation issues.

Non-Diversification Risks. The Fund may be subject to greater risk than a diversified fund because changes in the financial condition or market assessment of a single issuer may cause greater fluctuations in the value of the Fund’s shares.

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

Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.
Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus Non-Diversification Risks. The Fund may be subject to greater risk than a diversified fund because changes in the financial condition or market assessment of a single issuer may cause greater fluctuations in the value of the Fund’s shares.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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. The portfolio turnover rate of the Van Kampen U.S. Mortgage Fund (the predecessor fund) and the Fund for the most recent fiscal year was 370% of the average value of the portfolio.

Under normal market conditions, Invesco Advisers, Inc. (the Adviser) seeks to achieve the Fund’s investment objective by investing at least 80% of its net assets (plus any borrowings for investment purposes) in obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities at the time of investment. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in mortgage-backed securities.

Under normal market conditions, the Fund invests a substantial portion of its assets in U.S. mortgage-backed securities.

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

The Adviser purchases and sells securities for the Fund’s portfolio with a view towards seeking a high level of current income consistent with liquidity and safety of principal based on the analysis and expectations of the Adviser regarding prevailing interest rates and yield spreads between types of securities. Particular attention is given to the relative value of each security considered, its potential yield advantage and its interest rate sensitivity in light of current and expected economic conditions. The Fund may purchase and sell securities on a when-issued or delayed delivery basis. The Fund may borrow money for investment purposes. The Fund may purchase and sell options, futures contracts, options on futures contracts and interest rate swaps, inverse floating rate debt instruments and other related instruments, which are derivative instruments, for various portfolio management purposes, including to earn income, to facilitate portfolio management and to mitigate risks. In general terms, a derivative instrument is one whose value depends on (or is derived from) the value of an underlying asset, interest rate or index.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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

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

Market Risk. Market risk is the possibility that the market values of securities owned by the Fund will decline. The prices of debt securities tend to fall as interest rates rise, and such declines tend to be greater among debt securities with longer maturities or longer durations. The yields and market prices of U.S. government securities may move differently and adversely compared to the yields and market prices of the overall debt securities markets. U.S. government securities, while backed by the U.S. government, are not guaranteed against declines in their market prices.

Mortgage-Backed Securities Risk. Mortgage-backed securities may be more susceptible to further price declines than traditional debt securities in periods of rising interest rates because of extension risk (described below). In addition, mortgage-backed securities may benefit less than traditional debt securities during periods of declining interest rates because of prepayment risk (described below). When-issued and delayed delivery transactions are subject to changes in market conditions from the time of the commitment until settlement.

Credit Risk. Credit risk refers to an issuer’s ability to make timely payments of interest and principal. Credit risk should be low for the Fund because it invests primarily in obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities.

Income Risk. The income you receive from the Fund is based primarily on interest rates, which can vary widely over the short-and long-term. If interest rates drop, your income from the Fund may drop as well. The more the Fund invests in adjustable, variable or floating rate securities or in securities susceptible to prepayment risk, the greater the Fund’s income risk.

Prepayment Risk. If interest rates fall, the principal on debt securities held by the Fund may be paid earlier than expected. If this happens, the proceeds from a prepaid security would likely be reinvested by the Fund in securities bearing the new, lower interest rates, resulting in a possible decline in the Fund’s income and distributions to shareholders.

Extension Risk. The prices of debt securities tend to fall as interest rates rise. For mortgage-backed securities, if interest rates rise, borrowers may prepay mortgages more slowly than originally expected. This may further reduce the market value of the securities and lengthen their durations.

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

Borrowing Risks. The Fund may borrow money for investment purposes, which is known as leverage. The Fund may use leverage to seek to enhance income to shareholders, but the use of leverage creates the likelihood of greater volatility in the net asset value of the Fund’s shares. To the extent that income from investments made with such borrowed money exceeds the interest payable and other expenses of the leverage, the Fund’s net income will be less than if the Fund did not use. The Fund’s use of leverage also may impair the ability of the Fund to maintain its qualification for federal income tax purposes as a regulated investment company.

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s performance to that of a broad-based securities market benchmark and a style specific benchmark. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of its future performance.

The returns for periods prior to June 1, 2010 are those of the Class A, Class B, Class C, and Class I Shares of the predecessor fund. The predecessor fund was advised by Van Kampen Asset Management. Class A, Class B, Class C, and Class I shares of the predecessor fund were reorganized into Class A, Class B, Class C, and Class Y shares, respectively, of the Fund on June 1, 2010. Class A, Class B, Class C, and Class Y shares’ returns of the Fund will be different from the predecessor fund as they have different expenses. Performance for Class A and Class B shares have been restated to reflect the Fund’s applicable sales charge. Year-to-date returns include returns of the Fund for the periods ending on or after June 1, 2010.

Updated performance information is available on the Fund’s Web site at www.invesco.com/us.

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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 67% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 67.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund and the Underlying Funds
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying Funds Invesco Balanced Risk
 Retirement Now Fund
Invesco Balanced-Risk Allocation Fund 60.00%
Liquid Assets Portfolio 20.00%
Premier Portfolio 20.00%
Total100%

The Fund’s name indicates that an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Real return is total return reduced by the impact of inflation.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund's investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund's commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund's investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio's investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers' acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Premier Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Premier Portfolio invests in conformity with the Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Premier Portfolio maintains a dollar-weighted portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Premier Portfolio invests from time to time in U.S. dollar-denominated foreign securities. Premier Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Premier Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Premier Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. Premier Portfolio may also invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Industry Focus Risk. To the extent an underlying fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the underlying fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing; changes in government regulation and interest rates; and overall economy.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Money Market Fund Risk. Although the underlying fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the underlying fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the underlying fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the underlying fund’s $1.00 share price. The credit quality of the underlying fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the underlying fund’s share price. An underlying fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the underlying fund is managed, possibly negatively impacting its return. Additionally, the underlying fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities.

Municipal Securities Risk. An underlying fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the underlying fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Repurchase Agreement Risk. If the seller of a repurchase agreement in which an underlying fund invests defaults on its obligation or declares bankruptcy, the underlying fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary's investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.
Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution 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.
Risk Money Market Fund [Text] rr_RiskMoneyMarketFund

Money Market Fund Risk. Although the underlying fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the underlying fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the underlying fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the underlying fund’s $1.00 share price. The credit quality of the underlying fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the underlying fund’s share price.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 67% of the average value of its portfolio.

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying Funds Invesco Balanced Risk
 Retirement Now Fund
Invesco Balanced-Risk Allocation Fund 60.00%
Liquid Assets Portfolio 20.00%
Premier Portfolio 20.00%
Total100%

The Fund’s name indicates that an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Real return is total return reduced by the impact of inflation.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund’s investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund’s commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund’s investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Industry Focus Risk. To the extent an underlying fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the underlying fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing; changes in government regulation and interest rates; and overall economy.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Money Market Fund Risk. Although the underlying fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the underlying fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the underlying fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the underlying fund’s $1.00 share price. The credit quality of the underlying fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the underlying fund’s share price. An underlying fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the underlying fund is managed, possibly negatively impacting its return. Additionally, the underlying fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities.

Municipal Securities Risk. An underlying fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the underlying fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Repurchase Agreement Risk. If the seller of a repurchase agreement in which an underlying fund invests defaults on its obligation or declares bankruptcy, the underlying fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.

Subsidiary Risk. By investing in the Subsidiary's, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

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 the same.

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

Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 103% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 103.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund and the Underlying Funds
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

 Invesco Balanced-Risk
Underlying FundsRetirement 2010 Fund
Invesco Balanced-Risk Allocation Fund61.00%
Liquid Assets Portfolio19.50%
Premier Portfolio19.50%
Total100%

Note: Target Fund weightings are rounded to the nearest hundredths and may not add to 100% due to rounding. See SAI for exact target weightings.

The Fund’s name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund’s shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund’s target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund’s investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund’s commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund’s investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Premier Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Premier Portfolio invests in conformity with the Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Premier Portfolio maintains a dollar-weighted portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Premier Portfolio invests from time to time in U.S. dollar-denominated foreign securities. Premier Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Premier Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Premier Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. Premier Portfolio may also invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

Foreign Securities Risk. An underlying fund's foreign investments may be affected by changes in a foreign country’s exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Industry Focus Risk. To the extent an underlying fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the underlying fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing; changes in government regulation and interest rates; and overall economy.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Money Market Fund Risk. Although the underlying fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the underlying fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the underlying fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the underlying fund’s $1.00 share price. The credit quality of the underlying fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the underlying fund’s share price. An underlying fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the underlying fund is managed, possibly negatively impacting its return. Additionally, the underlying fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities.

Municipal Securities Risk. An underlying fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the underlying fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Repurchase Agreement Risk. If the seller of a repurchase agreement in which an underlying fund invests defaults on its obligation or declares bankruptcy, the underlying fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 103% of the average value of its portfolio.

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

 Invesco Balanced-Risk
Underlying FundsRetirement 2010 Fund
Invesco Balanced-Risk Allocation Fund61.00%
Liquid Assets Portfolio19.50%
Premier Portfolio19.50%
Total100%

Note: Target Fund weightings are rounded to the nearest hundredths and may not add to 100% due to rounding. See SAI for exact target weightings.

The Fund’s name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund’s shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund’s target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund’s investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund’s commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund’s investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Premier Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Premier Portfolio invests in conformity with the Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Premier Portfolio maintains a dollar-weighted portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Premier Portfolio invests from time to time in U.S. dollar-denominated foreign securities. Premier Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Premier Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Premier Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. Premier Portfolio may also invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Industry Focus Risk. To the extent an underlying fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the underlying fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing; changes in government regulation and interest rates; and overall economy.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Money Market Fund Risk. Although the underlying fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the underlying fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the underlying fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the underlying fund’s $1.00 share price. The credit quality of the underlying fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the underlying fund’s share price. An underlying fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the underlying fund is managed, possibly negatively impacting its return. Additionally, the underlying fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities.

Municipal Securities Risk. An underlying fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the underlying fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Repurchase Agreement Risk. If the seller of a repurchase agreement in which an underlying fund invests defaults on its obligation or declares bankruptcy, the underlying fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 57% of the average value of its portfolio.

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying FundsInvesco Balanced-Risk
 Retirement 2020 Fund
Invesco Balanced-Risk Allocation Fund97.00%
Liquid Assets Portfolio1.50%
Premier Portfolio1.50%
Total100%

The Fund’s name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund’s shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund’s target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund’s investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund’s commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund’s investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers' acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Industry Focus Risk. To the extent an underlying fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the underlying fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing; changes in government regulation and interest rates; and overall economy.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Money Market Fund Risk. Although the underlying fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the underlying fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the underlying fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the underlying fund’s $1.00 share price. The credit quality of the underlying fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the underlying fund’s share price. An underlying fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the underlying fund is managed, possibly negatively impacting its return. Additionally, the underlying fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities.

Municipal Securities Risk. An underlying fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the underlying fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Repurchase Agreement Risk. If the seller of a repurchase agreement in which an underlying fund invests defaults on its obligation or declares bankruptcy, the underlying fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying FundsInvesco Balanced-Risk
 Retirement 2020 Fund
Invesco Balanced-Risk Allocation Fund97.00%
Liquid Assets Portfolio1.50%
Premier Portfolio1.50%
Total100%

The Fund’s name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund’s shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund’s target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund’s investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund’s commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund’s investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Premier Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Premier Portfolio invests in conformity with the Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Premier Portfolio maintains a dollar-weighted portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Premier Portfolio invests from time to time in U.S. dollar-denominated foreign securities. Premier Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Premier Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Premier Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. Premier Portfolio may also invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

Industry Focus Risk. To the extent an underlying fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the underlying fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing; changes in government regulation and interest rates; and overall economy.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Money Market Fund Risk. Although the underlying fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the underlying fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the underlying fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the underlying fund’s $1.00 share price. The credit quality of the underlying fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the underlying fund’s share price. An underlying fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the underlying fund is managed, possibly negatively impacting its return. Additionally, the underlying fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities.

Municipal Securities Risk. An underlying fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the underlying fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Repurchase Agreement Risk. If the seller of a repurchase agreement in which an underlying fund invests defaults on its obligation or declares bankruptcy, the underlying fund may experience delays in selling the securities underlying the repurchase agreement resulting in losses.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.

U.S. Government Obligations Risk. Obligations issued by U.S. government agencies and instrumentalities may receive varying levels of support from the government, which could affect an underlying fund’s ability to recover should they default.

Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.
Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution 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.
Risk Money Market Fund [Text] rr_RiskMoneyMarketFund Money Market Fund Risk.

You should not rely on or expect the underlying fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the underlying fund’s $1.00 share price.

Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus Non-Diversification Risk.

A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

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 the same.

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

Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 32% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund and the Underlying Funds
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying FundsInvesco Balanced-Risk
 Retirement 2030 Fund
Invesco Balanced-Risk Allocation Fund100%
Liquid Assets Portfolio0%
Premier Portfolio0%
Total100%

The Fund’s name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund’s shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund’s target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund's investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund's investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund's international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund's fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund's commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund's obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund's investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary's derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund's investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio's management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset's theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio's investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio's investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers' acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio's investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio's investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers' acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Premier Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Premier Portfolio invests in conformity with the Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Premier Portfolio maintains a dollar-weighted portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Premier Portfolio invests from time to time in U.S. dollar-denominated foreign securities. Premier Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Premier Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Premier Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. Premier Portfolio may also invest in variable-rate demand notes.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund's and the Subsidiary'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 underlying fund's shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund's performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund's foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

Foreign Securities Risk. An underlying fund's foreign investments may be affected by changes in a foreign country's exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

Fund of Funds Risk. The Fund's performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds' 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.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary's investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund's business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund's income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund's Board of Trustees may authorize a significant change in investment strategy or liquidation.

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying FundsInvesco Balanced-Risk
 Retirement 2030 Fund
Invesco Balanced-Risk Allocation Fund100%
Liquid Assets Portfolio0%
Premier Portfolio0%
Total100%

The Fund’s name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund’s shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund’s target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund’s investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund’s commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund’s investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio maintains a dollar-weighted portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Premier Portfolio invests from time to time in U.S. dollar-denominated foreign securities.

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.

Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution 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.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

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 the same.

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

Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 26% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund and the Underlying Funds
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund's target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying FundsInvesco Balanced-Risk
 Retirement 2040 Fund
Invesco Balanced-Risk Allocation Fund100%
Liquid Assets Portfolio0%
Premier Portfolio0%
Total100%

The Fund's name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund's real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund's shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund's target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund's investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund's investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund's international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund's fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund's commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund's obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund's investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary's derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund's investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio's management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset's theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio's investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio's investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers' acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio's investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio's investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers' acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Premier Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Premier Portfolio invests in conformity with the Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Premier Portfolio maintains a dollar-weighted portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Premier Portfolio invests from time to time in U.S. dollar-denominated foreign securities. Premier Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Premier Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Premier Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. Premier Portfolio may also invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

Foreign Securities Risk. An underlying fund's foreign investments may be affected by changes in a foreign country's exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

Fund of Funds Risk. The Fund's performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds' 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.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary's investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund's business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund's income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund's Board of Trustees may authorize a significant change in investment strategy or liquidation.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock 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 the same.

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

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 26% of the average value of its portfolio.

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying FundsInvesco Balanced-Risk
 Retirement 2040 Fund
Invesco Balanced-Risk Allocation Fund100%
Liquid Assets Portfolio0%
Premier Portfolio0%
Total100%

The Fund’s name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund’s shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund’s target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund’s investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund’s commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund’s investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.

Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution 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.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

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 the same.

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

Portfolio Turnover aimgs_PortfolioTurnoverAltAbstract  
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 27% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 27.00%
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund and the Underlying Funds
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying FundsInvesco Balanced-Risk Retirement 2050
  Fund
Invesco Balanced-Risk Allocation Fund100%
Liquid Assets Portfolio 0.00%
Premier Portfolio0.00%
Total100%

The Fund’s name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund’s shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund’s target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund’s investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund’s commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund’s investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

Premier Portfolio. Premier Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Premier Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Premier Portfolio invests in conformity with the Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Premier Portfolio maintains a dollar-weighted portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Premier Portfolio invests from time to time in U.S. dollar-denominated foreign securities. Premier Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Premier Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Premier Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. Premier Portfolio may also invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 27% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to meet its investment objective by building a portfolio that includes Invesco Balanced-Risk Allocation Fund and two affiliated money market funds, Liquid Assets Portfolio and Premier Portfolio. The Fund will generally rebalance its assets to the Fund’s target allocations on a monthly basis. A list of the underlying funds and their approximate target fund weightings as of April 30, 2011 is set forth below:

Underlying FundsInvesco Balanced-Risk Retirement 2050
  Fund
Invesco Balanced-Risk Allocation Fund100%
Liquid Assets Portfolio 0.00%
Premier Portfolio0.00%
Total100%

The Fund’s name indicates the approximate date an investor in the Fund plans to retire and may stop making new investments in the Fund. Consistent with the Fund’s real return and capital preservation objectives, the Fund is designed for investors who expect to need all or most of their money in the Fund at retirement and for investors who plan to withdraw the value of their account in the Fund gradually after retirement. Once the asset allocation of the Fund has become similar to the asset allocation of the Invesco Balanced-Risk Retirement Now Fund, the Board of Trustees may approve combining the Fund with Invesco Balanced-Risk Retirement Now Fund if they determine that such a combination is in the best interests of the Fund’s shareholders. Such a combination will result in the shareholders of the Fund owning shares of Invesco Balanced-Risk Retirement Now Fund rather than the Fund. The Adviser expects such a combination to generally occur during the year of the Fund’s target retirement date.

The following chart displays how the Adviser expects the asset allocation for the Fund to change as its target retirement date approaches. The Fund employs a risk-balanced optimization process which accounts for the flat glide path (the glide path is the rate at which the asset mix changes over time) until approximately 10 years from the target retirement date. The glide path will become more conservative on a quarterly basis approximately 10 years from the target retirement date by gradually reducing the allocation to Invesco Balanced-Risk Allocation Fund and increasing the allocation to money market funds. The actual asset allocations for the Funds may differ from those shown in the chart below.

Investment Objectives and Strategies of the Underlying Funds

Invesco Balanced-Risk Allocation Fund. Invesco Balanced-Risk Allocation Fund’s investment objective is to provide total return with a low to moderate correlation to traditional financial market indices. Invesco Balanced-Risk Allocation Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

Invesco Balanced-Risk Allocation Fund invests, under normal conditions, in derivatives and other financially-linked instruments whose performance is expected to correspond to U.S. and international fixed income, equity and commodity markets. Invesco Balanced-Risk Allocation Fund may invest in derivatives and other financially-linked instruments such as futures, swap agreements, including total return swaps and may also invest in U.S. and foreign government debt securities and other securities such as exchange-traded funds (ETFs) and commodity-linked notes. Invesco Balanced-Risk Allocation Fund’s international investments will generally be in developed countries, but may also include emerging market countries. Invesco Balanced-Risk Allocation Fund’s fixed income investments are generally considered to be investment grade while Invesco Balanced-Risk Allocation Fund’s commodity markets exposure will generally be in the precious metals, agriculture, energy and industrial metals sectors. Invesco Balanced-Risk Allocation Fund will also invest in the Subsidiary and ETFs to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange-traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. Invesco Balanced-Risk Allocation Fund will generally maintain 60% of its total assets in cash and cash equivalent instruments including affiliated money market funds. Some of the cash holdings will serve as margin or collateral for the Fund’s obligations under derivative transactions. Invesco Balanced-Risk Allocation Fund’s investments in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the investments in derivatives create greater economic exposure than the amount invested. This means that Invesco Balanced-Risk Allocation Fund could lose more than originally invested in the derivative.

The Subsidiary is advised by Invesco and has the same investment objective as Invesco Balanced-Risk Allocation Fund and generally employs the same investment strategy but limits its investments to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds.

The Subsidiary, unlike Invesco Balanced-Risk Allocation Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leveraged and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary’s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. Invesco Balanced-Risk Allocation Fund will be subject to the risks associated with any investment by the Subsidiary to the extent of Invesco Balanced-Risk Allocation Fund’s investment in the Subsidiary.

Invesco Balanced-Risk Allocation Fund is non-diversified, which means that it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

Relative to traditional balanced portfolios, Invesco Balanced-Risk Allocation Fund will seek to provide greater capital loss protection during down markets. The portfolio’s management team will accomplish this through a three-step investment process.

The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset’s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of Invesco Balanced-Risk Allocation Fund.

The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and re-optimizes the portfolio periodically or when new assets are introduced to Invesco Balanced-Risk Allocation Fund.

The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas—opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure—by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market funds. By using derivatives, Invesco Balanced-Risk Allocation Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio.

Liquid Assets Portfolio. Liquid Assets Portfolio’s investment objective is to provide as high a level of current income as is consistent with the preservation of capital and liquidity. Liquid Assets Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Liquid Assets Portfolio invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Liquid Assets Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. Liquid Assets Portfolio invests in conformity with Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. Liquid Assets Portfolio maintains a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Liquid Assets Portfolio may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Liquid Assets Portfolio may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. Liquid Assets Portfolio will limit investments to those securities which are rated within the top rating category by rating agencies, commonly referred to as First Tier Securities, at the time of purchase.

In selecting securities for Liquid Assets Portfolio, the portfolio managers focus on securities that offer favorable prospects for current income consistent with the preservation of capital. The portfolio manager may invest in variable-rate demand notes.

The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.

Premier Portfolio. Premier Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity. Premier Portfolio’s investment objective may be changed by the Board of Trustees without shareholder approval.

Premier Portfolio invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. and foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes.

Premier Portfolio is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent.

Premier Portfolio maintains a dollar-weighted portfolio maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less.

Premier Portfolio invests from time to time in U.S. dollar-denominated foreign securities.

Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund and the Underlying Funds
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the Fund and the underlying funds are:

Active Trading Risk. Certain underlying funds engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

Commodity-Linked Notes Risk. An underlying 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 an underlying fund.

Commodity Risk. Certain of the underlying funds will invest in commodities through a wholly-owned subsidiary of that underlying fund organized under the laws of the Cayman Islands (the Subsidiary). Investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund and the Subsidiary 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 certain of the underlying fund’s and the Subsidiary’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 underlying fund’s shares.

Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.

Counterparty Risk. Many of the instruments that an underlying fund expects to hold may be subject to the risk that the other party to a contract will not fulfill its contractual obligations.

Credit Risk. The issuer of instruments in which an underlying 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.

Currency/Exchange Rate Risk. The dollar value of an underlying fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other investments and may be subject to market, interest rate, credit, leverage, counterparty and management risks. An underlying fund investing in a derivative could lose more than the cash amount invested or incur higher taxes. Over-the-counter derivatives 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 an underlying fund.

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

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

Exchange-Traded Notes Risk. Exchange-Traded Notes (ETNs) are subject to credit risk, including the credit risk of the issuer, and the value of the ETN 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 ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, 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 asset.

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

Fund of Funds Risk. The Fund’s performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.

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.

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

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

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

Market Risk. The prices of and the income generated by the underlying funds’ 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.

Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.

Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary’s investments, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), the underlying fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in U.S. registered investment companies. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.

Tax Risk. Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from commodity-linked notes as qualifying income based on a private letter ruling it has received from the Internal Revenue Service (IRS) holding that the income from a form of commodity-linked note constitutes qualifying income. Additionally, Invesco Balanced-Risk Allocation Fund intends to treat the income it derives from the Subsidiary as qualifying income based on a private letter ruling it has received from the IRS holding that the income of the Subsidiary attributable to Invesco Balanced-Risk Allocation Fund is income derived with respect to Invesco Balanced-Risk Allocation Fund’s business of investing in the stock of the Subsidiary and thus constitutes qualifying income. If, however, the IRS were to change its position with respect to the conclusions reached in these private letter rulings, such that Invesco Balanced-Risk Allocation Fund’s income from the Subsidiary and commodity-linked notes is not “qualifying income,” Invesco Balanced-Risk Allocation Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Invesco Balanced-Risk Allocation Fund’s Board of Trustees may authorize a significant change in investment strategy or liquidation.
