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 aimsf725781_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 58% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 58.00%
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 its net assets (plus borrowings for investment purposes) in securities of issuers engaged in energy-related industries. The Fund invests predominantly 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. Certain derivatives and other instruments may have the effect of leveraging the Fund’s portfolio.

The Fund may invest up to 100% of its net assets in foreign securities of issuers doing business in energy-related industries.

Generally, the Fund’s investments are divided among the four main energy subsectors: (1) major oil issuers; (2) energy services issuers; (3) oil and gas exploration/production issuers; and (4) natural gas and logistic pipeline issuers. Portfolio weightings among these and other subsectors will be adjusted according to current economic conditions. In selecting securities for the Fund, the portfolio managers use a research-oriented, bottom-up investment approach, focusing on reasonably priced energy issuers with above average production volume growth, as well as earnings, cash flow and asset value growth potential independent of commodity pricing. The investment strategy focuses on identifying issuers with the ability to increase production while controlling costs by implementing new technologies, locating new discoveries (such as oil, natural gas, and/or coal) or boosting production volumes. In general, the Fund emphasizes issuers that the portfolio managers believe are strongly managed and will generate above average long-term capital appreciation.

The portfolio managers will consider selling a security of an issuer if, among other things, (1) a security reaches its price target; (2) a change in fundamentals occur—either issuer specific or industry wide; (3) a change in management occurs; 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 (FDIC) 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:

Energy Industry Sector Risk. The businesses in which the Fund invests may be adversely affected by foreign, federal or state regulations governing energy production, distribution and sale as well as supply-and-demand for energy resources. Although individual security selection drives the performance of the Fund, short-term fluctuations in energy prices may cause price fluctuations in its shares.

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.

Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.

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.

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 30% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 30.00%
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 issuers engaged in exploring for mining, processing, or dealing and investing in gold and other precious metals such as silver, platinum and palladium, as well as diamonds (the gold and precious metals sector). The Fund invests predominantly 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. Certain derivatives and other instruments may have the effect of leveraging the Fund’s portfolio. The Fund may also invest in gold bullion.

The Fund considers an issuer to be doing business in the gold and precious metals sector if it meets at least one of the following tests: (1) at least 50% of its gross income or its net sales come from activities in the gold and precious metals sector; (2) at least 50% of its assets are devoted to producing revenues in the gold and precious metals sector; or (3) based on other available information, the portfolio manager determines that its primary business is within the gold and precious metals sector. The principal type of equity securities purchased by the Fund is common stock.

The Fund may invest up to 100% of its net assets in foreign securities of issuers doing business in the gold and precious metals sector. The Fund invests up to 10% of its assets in gold bullion.

The portfolio manager employs a disciplined investment strategy that emphasizes fundamental research, supported by quantitative analysis, portfolio construction and risk management techniques. Investments for the portfolio are selected bottom-up on a security-by-security basis focused on the strengths of individual issuers, rather than sector or country trends.

The portfolio manager will consider selling a security of an issuer if, among other things, (1) a security reaches its target price; (2) a change in fundamentals occurs – either issuer specific or industry wide; (3) a change in management occurs; or (4) a more attractive investment opportunity is identified.

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 issuers engaged in exploring for mining, processing, or dealing and investing in gold and other precious metals such as silver, platinum and palladium, as well as diamonds (the gold and precious metals sector). The Fund invests predominantly 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 (FDIC) 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.

Gold Bullion Risk. To the extent the Fund invests in gold bullion, it will earn no income. Appreciation in the market price of gold is the sole manner in which the Fund can realize gains on gold bullion, and such investments may incur higher storage and custody costs as compared to purchasing, holding and selling more traditional investments.

Gold and Precious Metals Industry Risk. Fluctuations in the price of gold and precious metals may affect the profitability of companies in the gold and precious metals sector. Changes in the political or economic conditions of countries where companies in the gold and precious metals sector are located may have a direct effect on the price of gold and precious metals.

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.

Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.

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.
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 (FDIC) or any other governmental agency.

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 aimsf725781_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 53% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 53.00%
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 issuers engaged in the design, production and distribution of products and services related to leisure activities of individuals (the leisure sector). The Fund invests predominantly 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. Certain derivatives may have the effect of leveraging the Fund’s portfolio.

The Fund may invest up to 25% of its total assets in foreign securities of issuers doing business in the leisure-related industries.

In constructing the portfolio, the portfolio managers take macroeconomic and industry trends into consideration. Quantitative screens are used to help identify attractive security candidates within the universe of leisure-related issuers. Portfolio candidates are further refined by fundamental analysis performed at the issuer level which includes an evaluation of industry dynamics, competitive intensity and drivers of growth. Financial models are used to review historical performance and forecast two to three years into the future. Internally generated earnings-per-share (EPS) estimates are used to calculate valuation targets and a combination of multiples are used to establish price targets. The portfolio managers construct the portfolio with the goal of holding approximately 40-75 individual securities with an average investment horizon of 18 to 24 months. In general, the portfolio managers favor issuers with attractive revenue growth, strong free cash flow generation and returns on invested capital that are in excess of the issuer’s weighted average cost of capital. Additionally, the portfolio managers seek issuers requiring low capital intensity with management teams that appear to be good stewards of capital.

The portfolio managers will consider selling a security for the following reasons: (1) a more attractive investment opportunity is identified, (2) the valuation reaches the portfolio manager’s target price, (3) a change in fundamentals occur—either issuer specific or industry wide, or (4) a security’s technical profile indicates negative underlying information which is further determined to have violated a fundamental investment thesis.
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 issuers engaged in the design, production and distribution of products and services related to leisure activities of individuals (the leisure sector). The Fund invests predominantly 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 (FDIC) 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.

Leisure Industry Risk. The leisure sector depends on consumer discretionary spending, which generally falls during economic downturns. Securities of gambling casinos are often subject to high price volatility and are considered speculative. Securities of companies that make video and electronic games may be affected by the games’ risk of rapid obsolescence.

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.

Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.

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.

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 aimsf725781_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 42% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 42.00%
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 issuers engaged in technology-related industries. The Fund invests predominantly 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. Certain derivatives may have the effect of leveraging the Fund's portfolio.

The Fund may invest up to 50% of its total assets in foreign securities of issuers doing business in technology-related industries.

In selecting securities for the Fund, the portfolio managers use a research-oriented bottom-up investment approach, focusing on issuer fundamentals and growth prospects. Security selection is then further refined by valuation and timeliness analysis. In general, the Fund invests in issuers that the portfolio managers believe currently exhibit or will develop a sustainable competitive advantage, a free cash flow generating business model and strong returns on invested capital. Technology issuers able to capitalize on the key secular themes identified by the portfolio managers are emphasized.

Valuation plays a critical role in the security selection process. The primary metric used by the portfolio managers to determine a security's target valuation is cash flow. In addition to valuation analysis, the portfolio managers analyze product cycle and seasonality-driven measures to help determine the best time to purchase or sell a security.

While the portfolio managers may invest in securities of any market capitalization, they tend to favor mid- and large-cap securities to avoid liquidity problems that can be associated with some small-cap securities.

The portfolio managers will consider selling the security of an issuer if, among other things, (1) a security's price reaches its valuation target; (2) an issuer's fundamentals deteriorate; (3) it no longer meets the investment criteria; 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 (FDIC) 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.

Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.

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.

Technology Sector Risk. Many products and services offered in technology-related industries are subject to rapid obsolescence, which may lower the value of the issuers in this sector.

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 17% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 17.00%
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 issuers engaged in utilities-related industries. The Fund invests predominantly 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% requirement. Certain derivatives and other investments may have the effect of leveraging the Fund’s portfolio.

The Fund may invest up to 25% of its net assets in foreign securities of issuers doing business in utilities-related industries.

In selecting investments, the portfolio managers seek to identify issuers predominantly within the electric utility, natural gas, water and telecommunications industries. The investment team generally emphasizes issuers with solid balance sheets and operational cash flow that supports sustained or increasing dividends. Through fundamental research, financial statement analysis and multiple valuation metrics, the management team estimates a target price for each security over a 2-3 year investment horizon. The portfolio managers then construct a portfolio which they believe provides the best total return potential based on a combination of price appreciation, dividend income and a favorable risk profile.

The portfolio managers consider whether to sell a particular security when any of these factors materially change.

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 (FDIC) 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.

Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.

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.

Utilities Sector Risk. The following factors may affect the 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.

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 17% 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 invests, under normal circumstances, at least 80% of net assets (plus borrowings for investment purposes) in securities of issuers engaged in utilities-related industries. The Fund invests predominantly 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% requirement. Certain derivatives and other investments may have the effect of leveraging the Fund’s portfolio.

The Fund may invest up to 25% of its net assets in foreign securities of issuers doing business in utilities-related industries.

In selecting investments, the portfolio managers seek to identify issuers predominantly within the electric utility, natural gas, water and telecommunications industries. The investment team generally emphasizes issuers with solid balance sheets and operational cash flow that supports sustained or increasing dividends. Through fundamental research, financial statement analysis and multiple valuation metrics, the management team estimates a target price for each security over a 2-3 year investment horizon. The portfolio managers then construct a portfolio which they believe provides the best total return potential based on a combination of price appreciation, dividend income and a favorable risk profile.

The portfolio managers consider whether to sell a particular security when any of these factors materially change.

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 (FDIC) 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.

Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.

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.

Utilities Sector Risk. The following factors may affect the 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.

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 (FDIC) 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 aimsf725781_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 Morgan Stanley U.S. Mid Cap Value Portfolio (the predecessor fund) and the Fund for the fiscal year ended September 30, 2010 was 60% of the average value of the portfolio. The portfolio turnover rate of the Fund for the fiscal period October 1, 2010 to April 30, 2011 was 26% 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 circumstances, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in common stocks of companies traded on a U.S. securities exchange with capitalizations within the range of companies included in the Russell Midcap® Value Index. As of July 29, 2011, these market capitalizations range between $480 million and $18.3 billion. The Fund may purchase stocks that typically do not pay dividends. In pursuing its investment objective, the Fund’s investment adviser, Invesco Advisers, Inc. (the Adviser), seeks attractively valued companies experiencing a change that the Adviser believes could have a positive impact on a company’s outlook, such as a change in management, industry dynamics or operational efficiency. The Adviser looks at the various attributes of a company to determine whether the company is attractively valued in the current marketplace, such as its price/earnings ratio, price/book value ratio and price/sales ratio. The Adviser sells a security when it believes that it no longer fits the Fund’s investment criteria. The Fund may also use derivative instruments as discussed below. These derivative instruments used by the Fund will be counted towards the 80% policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.

The Fund may invest up to 20% of its net assets in securities of foreign issuers, including issuers located in emerging market or developing countries. The securities in which the Fund may invest may be denominated in U.S. dollars or in currencies other than U.S. dollars. The Fund may also invest up to 20% of its assets in real estate investment trusts (REITs).

The Fund may, but it is not required to, use derivative instruments for a variety of purposes, including hedging, risk management, portfolio management or to earn income. The Fund’s use of derivatives may involve the purchase and sale of derivative instruments such as futures, swaps, options, and other related instruments and techniques. The Fund may utilize forward foreign currency exchange contracts, which are also derivatives, in connection with its investments 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 (FDIC) 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:

Common Stock. In general, stock and other equity security values fluctuate, and sometimes widely fluctuate, in response to activities specific to the company as well as general market, economic and political conditions.

Medium Capitalization Companies. Investing in securities of medium capitalization companies may involve greater risk than is customarily associated with investing in more established companies. Often, medium capitalization companies and the industries in which they are focused are still evolving. Medium-sized companies often have less predictable earnings and more limited product lines, markets, distribution channels or financial resources. The market movements of equity securities of medium-sized companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general.

Value Investing Style. 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.

Foreign and Emerging Market Securities. Investments in foreign markets entail special risks such as currency, political, economic and market risks. There also may be greater market volatility, less reliable financial information, higher transaction and custody costs, decreased market liquidity and less government and exchange regulation associated with investments in foreign markets. The risks of investing in emerging market countries are greater than risks associated with investments in foreign developed countries. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments.

Foreign Currency. The Fund’s investments may be denominated in foreign currencies. The value of foreign currencies fluctuates relative to the value of the U.S. dollar. Since the Fund may invest in such non-U.S. dollar-denominated securities, and therefore may convert the value of such securities into U.S. dollars, changes in currency exchange rates can increase or decrease the U.S. dollar value of the Fund’s assets. The Adviser may use derivatives to reduce this risk. The Adviser may in its discretion choose not to hedge against currency risk. In addition, certain market conditions may make it impossible or uneconomical to hedge against currency risk.

REITs. REITs are susceptible to risks associated with the ownership of real estate and the real estate industry in general. In addition, investments in REITs may involve duplication of management fees and certain other expenses. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for the Fund.

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.

Risk Lose Money [Text] rr_RiskLoseMoney As with any mutual fund investment, loss of money is a risk of investing.

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 style specific benchmark, a peer group benchmark and a broad-based securities market benchmark comprised of funds 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 I, Investment Class and Class P shares of the predecessor fund. The predecessor fund was advised by Morgan Stanley Investment Management Inc. Class I and Investment Class shares of the predecessor fund were reorganized into Class Y shares of the Fund on June 1, 2010. Class P shares of the predecessor fund were reorganized into Class A shares of the Fund on June 1, 2010. Class Y and Class A shares’ returns of the Fund will be different from the predecessor fund as they have different expenses. Predecessor fund performance for Class A shares has been restated to reflect the Fund’s applicable sales charge.

The returns shown for Class B and Class C shares are those of Class P shares of the predecessor fund. Class B and Class C shares’ returns will be different from the predecessor fund as they have different expenses. Class B and Class C shares commenced operations on June 1, 2010.

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 American Value Fund (the predecessor fund) and the Fund for the fiscal year ended June 30, 2010 was 50% of the average value of the portfolio. The portfolio turnover rate of the Fund for the fiscal period July 1, 2010 to April 30, 2011 was 28% of the average value of portfolio.

Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objective by investing predominantly in a portfolio of equity securities of small- to medium-sized U.S. corporations. The Adviser seeks attractively valued companies experiencing a change that could have a positive impact on a company’s outlook. The Adviser emphasizes a value style of investing, seeking securities of companies that the Adviser believes are undervalued. The Fund may dispose of a security whenever, in the opinion of the Adviser, factors indicate it is desirable to do so. Such factors include a change in economic or market factors in general or with respect to a particular industry, a change in the market trend or other factors affecting an individual security, changes in the relative market performance or appreciation possibilities offered by individual securities and other circumstances bearing on the desirability of a given investment.

Under normal market conditions, the Fund invests at least 65% of its total assets in equity securities of small- to medium-sized companies. Under current market conditions, the Adviser defines small-and medium-sized corporations by reference to those with market capitalizations up to the largest companies represented in the Russell Midcap® Index, a medium-sized capitalization company index which consists of companies with capitalizations up to approximately $19.2 billion as of July 29, 2011. The Fund invests in equity securities, which are common stocks and preferred stocks; convertible securities and equity-linked securities; and rights and warrants to purchase common stocks and other equity interests, such as partnership and trust interests.

The Fund may invest up to 20% of its total assets in securities of foreign issuers and may invest up to 20% of its total assets in real estate investment trusts (REITs). The Fund may purchase and sell options, futures contracts and, options on futures contracts, which are derivative instruments, for various portfolio management purposes and to mitigate risks. In general terms, a derivative instrument is one whose value depends on (or is derived from) the value of an underlying asset, interest rate or index.

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 (FDIC) 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 equity securities generally are affected by changes in the stock markets, which fluctuate substantially over time, sometimes suddenly and sharply. 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.

Risks of Small and Medium Capitalization Companies. Small and medium capitalization companies often have less predictable earnings, more limited product lines, markets, distribution channels or financial resources and the management of such companies may be dependent upon one or few key people. The market movements of equity securities of small and medium capitalization companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general and small capitalization companies, in particular, are generally less liquid than equity securities of larger companies.

Risks of Investing in Value Stocks. Value stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Value stocks can continue to be undervalued for long periods of time and may not ever realize their full value.

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 Fund 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.

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, style-specific benchmark and a peer group benchmark comprised of funds 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 shown for periods prior to June 1, 2010 are those of the Class A, Class B, Class C, Class I and Class R Shares of the predecessor fund. The predecessor fund was advised by Van Kampen Asset Management. Class A, Class B, Class C, Class I and Class R shares of the predecessor fund were reorganized into Class A, Class B, Class C, Class Y and Class R shares, respectively, of the Fund on June 1, 2010. Class A, Class B, Class C, Class R 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.

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 Comstock Fund (the predecessor fund) and the Fund for the fiscal year ended December 31, 2010 was 18% of the average value of the portfolio. The portfolio turnover rate of the Fund for the fiscal period January 1, 2011 to April 30, 2011 was 10% of the average value of the portfolio.

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 objective by investing in a portfolio of equity securities, consisting principally of common stocks, preferred stocks and securities convertible into common and preferred stocks. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks at the time of investment. The Fund emphasizes a value style of investing seeking 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 issuers of small-, medium- or large-sized companies. The Fund may invest up to 25% of its total assets in securities of foreign issuers. The Fund may invest up to 10% of its total assets in real estate investment trusts (REITs).

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.

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 (FDIC) 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 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 often fluctuate more than stock prices of larger companies or the market averages in general. In addition, such companies typically are subject to a greater degree of change in earnings and business prospects than are larger companies and may be less liquid than larger-sized companies. In addition, small- and medium-sized companies may have more limited markets, financial resources and product lines, and may lack the depth of management of larger companies.

Value Investing. A value style of investing 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 equity securities are less than the returns on other styles of investing or the overall stock markets.

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.

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.

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.

Risks of Investing in Real Estate Investment Trusts (REITs). Investing in REITs makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general. 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. Investments in REITs may involve duplication of management fees and certain other expenses.

Risks of Using Derivative Instruments. Derivative transactions involve risks different from direct investments in underlying securities. 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.

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 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 shown for periods prior to June 1, 2010 are those of the Class A, Class B, Class C, Class I and Class R shares of the predecessor fund. The predecessor fund was advised by Van Kampen Asset Management. Class A, Class B, Class C, Class I and Class R shares of the predecessor fund were reorganized into Class A, Class B, Class C, Class Y and Class R shares, respectively, on June 1, 2010. Class A, Class B, Class C, Class Y and Class R shares’ returns of the Fund will be different from the predecessor fund as they have different expenses. Performance for Class A and B shares has been restated to reflect the Fund’s applicable sales charge.

In addition, small- and medium-sized companies may have more limited markets, financial resources and product lines, and may lack the depth of management of larger companies.

Value Investing. A value style of investing 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 equity securities are less than the returns on other styles of investing or the overall stock markets.

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.

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.

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.

Risks of Investing in Real Estate Investment Trusts (reits). Investing in REITs makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general. 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. Investments in REITs may involve duplication of management fees and certain other expenses.

Risks of Using Derivative Instruments. Derivative transactions involve risks different from direct investments in underlying securities. 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.

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 (FDIC) or any other government agency.

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 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 shares of the predecessor fund. The predecessor fund was advised by Van Kampen Asset Management. Institutional Class shares’ returns of the Fund will be different from the predecessor fund as they have different expenses.

Updated performance information is available on the Fund’s Web site at www.invesco.com/us.

[1] Class Y shares' performance shown prior to the inception date is that of Investor Class shares and includes the 12b-1 fees applicable to Investor Class shares. Investor Class shares' performance reflects any applicable fee waiver and/or expense reimbursement.
[2] The Fund has elected to use the MSCI World Energy Index as its style specific index rather than the Dow Jones U.S. Oil & Gas Index. The MSCI World Energy Index more closely reflects the perofmrance of the types of securities in which the Fund invests.
[3] "Total Annual Fund Operating Expenses" have been restated and reflect the reorganization of one or more affiliated investment companies into the Fund.
[4] Effective May 23, 2011, Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed, through at least June 30, 2013 to waive advisory fees and/or reimburse expenses of all shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Wiaver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Class A, Class B, Class C, Class Y and Investor Class shares to 1.32%, 2.07%, 2.07%, 1.07% and 1.32%, respectively, of average daily net assets. Unless the Board of Trustees and Invesco mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2013.
[5] "Other Expenses" and "Total Annual Fund Operating Expenses" are based on estimated amounts for the current fiscal year.
[6] The Adviser has contractually agreed, through at least June 30, 2012, to waive advisory fees and/or reimburse expenses of all shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed below) of Class A shares to 1.27%, Class B shares to 2.02%, Class C shares to 2.02% and Class Y shares to 1.02% of average daily net assets. In determining the Adviser's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement to exceed the limit reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items; and (v) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Acquired Fund Fees and Expenses are also excluded in determining such obligation. Unless the Board and Invesco mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2012.
[7] Class B and Class C shares' performance shown prior to the inception date is that of the predecessor fund's Class P shares restated to reflect the higher 12b-1 fees applicable to Class B and Class C shares.
[8] The Fund has elected to include three benchmark indices: the Russell Midcap Value Index, the Lipper Mid-Cap Value Funds Index and the S&P 500 Index. The Russell Midcap Value Index is the style-specific benchmark and is the proxy that most appropriately reflects the Fund's investment process. The Lipper Mid-Cap Value Funds Index has been added as a peer group benchmark. The Fund has elected to use the S&P 500 as its broad-based benchmark instead of the Russell Midcap Value Index to provide investors a broad proxy for the U.S. market.
[9] "Distribution and/or Service (12b-1) Fees" have been estimated for the current fiscal year.
[10] Institutional Class shares performance shown prior to the inception date is that of the predecessor fund's Class A shares and includes the 12b-1 fees applicable to Class A shares. The inception date of the predecessor fund's Class A shares is October 18, 1993.
[11] "Distribution and/or Service (12b-1) Fees" have been restated for the current fiscal year.
[12] Institutional Class shares performance shown prior to the inception date is that of the predecessor fund's Class A shares and includes the 12b-1 fees applicable to Class A shares. The inception date of the predecessor fund's Class A shares is October 7, 1968.
[13] The Lipper Large-Cap Value Funds Index has been added as a peer group benchmark.
