Portfolio Turnover pf891079_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 the Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance. Since the Fund had not commenced operations as of the most recent fiscal period, it has not yet reported a portfolio turnover rate as of the date of this Prospectus.
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by allocating assets among proprietary technically-based trend following strategies. The Fund takes long and short positions in broad index based securities (primarily domestically-listed foreign equity exchange-traded funds (“ETFs”)) based on long and intermediate term trends. The Fund also employs short term counter trend strategies that seek to hedge the trend following strategy and mitigate risk, while seeking to profit from short term market volatility. The strategies are intended to have low correlation with market benchmarks and with each other.

Anchor Capital Management Group, Inc. (“Anchor”), sub-adviser of the Fund, will allocate Fund assets among strategies that it believes offer the potential for attractive investment returns individually and that are expected to blend within the Fund’s portfolio so that it will have lower correlation and lower volatility relative to the market. In seeking to take advantage of increases or declines in the price of equity securities or indexes, the Fund may use stock baskets (groups of stocks that may be purchased through a single transaction) and exchange-traded notes (“ETNs”). In executing its counter trend strategy, the Fund may rotate investment positions among securities typically correlated to specific countries or regions. Security selection is determined through Anchor’s mathematical and statistical models; however, Anchor may alter such selection based on its assessment of current market conditions and other factors.

As part of its investment strategies, Anchor actively employs the use of cash and cash equivalents in an attempt to sidestep market declines and lower overall portfolio volatility. In particular, the Fund may invest all or substantially all of its assets in cash or cash equivalents when Anchor determines that market conditions so warrant. To the extent the Fund is invested heavily in cash, it may not achieve its investment objective and may experience negative returns.

The Fund may use derivatives, primarily swaps, options and futures contracts, as substitutes for securities in which the Fund can invest. The Fund may also use derivatives to an unlimited extent to hedge various investments for risk management and speculative purposes.

The Fund may invest, directly and indirectly (through derivatives and other pooled investment vehicles (including ETFs)), in securities of issuers of any market capitalization. The Fund may invest without limitation in investments tied economically to any country in the world, including emerging countries. The Fund is non-diversified as defined in the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund is not intended to be a complete investment program.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Equity Securities Risk is the risk that stock prices will fall over short or long periods of time. In addition, common stocks represent a share of ownership in a company, and rank after bonds and preferred stock in their claim on the company’s assets in the event of bankruptcy.

Exchange-Traded Funds Risk is the risk that the ETFs in which the Fund invests will not be able to replicate exactly the performance of the indices they track and may result in a loss. In addition, shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company when the Fund invests in shares of another investment company.

Short Sales Risk is the risk of loss associated with any appreciation on the price of a security borrowed in connection with a short sale. The Fund may engage in short sales that are not made “against-the-box,” which means that the Fund may sell short securities even when they are not actually owned or otherwise covered at all times during the period the short position is open. Short sales that are not made “against-the-box” theoretically involve unlimited loss potential since the market price of securities sold short may continuously increase.

Derivatives Risk is the risk that an investment in derivatives, such as swaps, options and futures, may not correlate completely to the performance of the underlying securities or index and may be volatile, and may result in a loss greater than the principal amount invested. Equity derivatives may also be subject to liquidity risk, as well as the risk that the derivative is mispriced and that the value established for a derivative may be different than what would be produced through the use of another methodology or if it had been priced using market quotations.

Counterparty Risk is the risk that a counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations.

Currency Risk is the risk that fluctuations in exchange rates will adversely affect the value of the Fund’s foreign currency holdings and investments denominated in foreign currencies.

Foreign Investment Risk is the risk that investing in foreign (non-U.S.) securities either directly or indirectly may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid. These risks may be heightened for emerging markets securities.

Emerging Markets Risk is the risk of investing in securities of companies located in emerging market countries, which primarily includes increased foreign investment risk. Emerging markets countries may have unstable governments and/or economies that are subject to sudden change, and may also lack the legal, business and social framework to support securities markets, which tends to make investments less liquid and more volatile.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Despite gains in some markets after steep declines during certain periods of 2008-2009, negative conditions and price declines may return unexpectedly and dramatically. In addition, the Fund could experience a loss when selling securities in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities sold.

Hedging Risk is the risk that, although intended to limit or reduce investment risk, hedging strategies may also limit or reduce the potential for profit. There is no assurance that hedging strategies will be successful.

Illiquid and Restricted Securities Risk is the risk that the Adviser may not be able to sell illiquid or restricted securities at the price it would like or may have to sell them at a loss. Securities of non-U.S. issuers, and emerging markets securities in particular, are subject to illiquidity risk.

Management Risk is the risk that the Adviser or Anchor may be incorrect in its assessment of the intrinsic value of the securities the Fund holds which may result in a decline in the value of Fund shares and failure to achieve its investment objective. The Fund’s portfolio managers use quantitative analyses and/or models. Any imperfections or limitations in such analyses and models could affect the ability of the portfolio managers to implement strategies.

Mid-Cap Company Risk is the risk of investing in securities of mid-cap companies that could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Small-Cap Company Risk is the risk that investing in the securities of small-cap companies either directly or indirectly through investments in Underlying Funds may pose greater market and liquidity risks than larger, more established companies, because of limited product lines and/or operating history, limited financial resources, limited trading markets, and the potential lack of management depth. In addition, the securities of such companies are typically more volatile than securities of larger capitalization companies.

Exchange-Traded Notes Risk is the risk that ETNs in which the Fund may invest are subject to credit risk and the value of an ETN may vary and may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities or other related markets, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events. ETNs are debt securities whose returns are linked to a particular index. The Fund will bear its proportionate share of any fees and expenses borne by the ETN.

Model Risk is the risk that the models used by the Fund to determine or guide investment decisions may not achieve the objectives of the Fund. Additionally, the portfolio manager of the Fund is able to adjust the models or, under certain adverse conditions, to deviate from the models employed by the Fund. Such adjustments or deviations may not achieve the objectives of the Fund and may produce lower returns and/or higher volatility compared to what the returns and volatility of the Fund would have been if the portfolio manager had not adjusted or deviated from the models.

Non-Diversification Risk is the risk that an investment in the Fund could fluctuate in value more than an investment in a diversified fund. As a non-diversified fund for purposes of the 1940 Act the Fund may invest a larger portion of its assets in the securities of a few issuers than a diversified fund. A non-diversified fund’s investment in fewer issuers may result in the Fund’s shares being more sensitive to the economic results of those issuers.

Portfolio Turnover Risk is the risk that the Fund’s high portfolio turnover will increase its transaction costs and may result in increased realization of net short-term capital gains (which are taxable to shareholders as ordinary income when distributed to them), higher taxable distributions and lower after-tax performance.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any mutual fund, there is no guarantee that the Fund will achieve its goal.

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

The Fund seeks to achieve its investment objective under normal market conditions by allocating assets among proprietary technically-based trend following strategies. The Fund primarily takes long and short positions with respect to securities that are highly correlated to high yield corporate bonds (also known as “junk bonds”) based on long, intermediate, and short term trends. Such securities primarily will include domestically-listed exchange-traded funds (“ETFs”), exchange-traded notes (“ETNs”) and mutual funds with high yield corporate bond exposure in any industry or sector. Security selection is determined through Anchor Capital Management Group, Inc.’s (“Anchor” or the “Sub-Adviser”) mathematical and statistical models; however, the Sub-Adviser may alter such selection based on its assessment of current market conditions and other factors.

The Sub-Adviser also actively employs the use of cash and cash equivalents as a strategic asset class in an attempt to both sidestep market declines as well as lower overall portfolio volatility, and the Fund may make investments in cash, cash equivalents and short-term debt securities and/or money market instruments in response to adverse market, economic or political conditions. In particular, the Fund may invest all or substantially all of its assets in cash or cash equivalents when the Sub-Adviser determines that market conditions so warrant. To the extent the Fund is invested heavily in cash, it may not achieve its investment objective and may experience negative returns.

The Fund may use derivatives, primarily swaps, options and futures contracts, as substitutes for securities in which the Fund can invest. The Fund may also use derivatives to an unlimited extent to hedge various investments for risk management and speculative purposes.

The Fund may invest, directly and indirectly (through derivatives and other pooled investment vehicles (including ETFs, ETNs, and mutual funds)), in securities of issuers of any credit quality. The Fund may invest without limitation in investments tied economically to any country in the world, including emerging market countries.

The Fund is non-diversified as defined in the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund is not intended to be a complete investment program.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Equity Securities Risk is the risk that stock prices will fall over short or long periods of time. In addition, common stocks represent a share of ownership in a company, and rank after bonds and preferred stock in their claim on the company’s assets in the event of bankruptcy.

Exchange-Traded Funds Risk is the risk that the ETFs in which the Fund invests will not be able to replicate exactly the performance of the indices they track and may result in a loss. In addition, shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company when the Fund invests in shares of another investment company.

High Yield Securities Risk is the risk that high yield securities or unrated securities of similar credit quality (commonly known as “junk bonds”) are more likely to default than higher rated securities. High yield securities are regarded as speculative with respect to the issuer’s capacity to pay interest and to repay principal. The market value of these securities is more sensitive to corporate developments and economic conditions and can be volatile. Market conditions can diminish liquidity and make accurate valuations difficult to obtain.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Credit Risk is the risk that the Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Short Sales Risk is the risk of loss associated with any appreciation on the price of a security borrowed in connection with a short sale. The Fund may engage in short sales that are not made “against-the-box,” which means that the Fund may sell short securities even when they are not actually owned or otherwise covered at all times during the period the short position is open. Short sales that are not made “against-the-box” theoretically involve unlimited loss potential since the market price of securities sold short may continuously increase.

Derivatives Risk is the risk that an investment in derivatives, such as swaps, options and futures, may not correlate completely to the performance of the underlying securities or index and may be volatile, and may result in a loss greater than the principal amount invested. Equity derivatives may also be subject to liquidity risk, as well as the risk that the derivative is mispriced and that the value established for a derivative may be different than what would be produced through the use of another methodology or if it had been priced using market quotations.

Counterparty Risk is the risk that a counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations.

Currency Risk is the risk that fluctuations in exchange rates will adversely affect the value of the Fund’s foreign currency holdings and investments denominated in foreign currencies.

Foreign Investment Risk is the risk that investing in foreign (non-U.S.) securities either directly or indirectly may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid. These risks may be heightened for emerging markets securities.

Emerging Markets Risk is the risk of investing in securities of companies located in emerging market countries, which primarily includes increased foreign investment risk. Emerging markets countries may have unstable governments and/or economies that are subject to sudden change, and may also lack the legal, business and social framework to support securities markets, which tends to make investments less liquid and more volatile.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Despite gains in some markets after steep declines during certain periods of 2008-2009, negative conditions and price declines may return unexpectedly and dramatically. In addition, the Fund could experience a loss when selling securities in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities sold.

Hedging Risk is the risk that, although intended to limit or reduce investment risk, hedging strategies may also limit or reduce the potential for profit. There is no assurance that hedging strategies will be successful.

Illiquid and Restricted Securities Risk is the risk that the Adviser may not be able to sell illiquid or restricted securities at the price it would like or may have to sell them at a loss. Securities of non-U.S. issuers, and emerging markets securities in particular, are subject to illiquidity risk.

Management Risk is the risk that the Adviser or Anchor may be incorrect in its assessment of the intrinsic value of the securities the Fund holds which may result in a decline in the value of Fund shares and failure to achieve its investment objective. The Fund’s portfolio managers use qualitative analyses and/or models. Any imperfections or limitations in such analyses and models could affect the ability of the portfolio managers to implement strategies.

Mid-Cap Company Risk is the risk of investing in securities of mid-cap companies that could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Small-Cap Company Risk is the risk that investing in the securities of small-cap companies either directly or indirectly through investments in Underlying Funds may pose greater market and liquidity risks than larger, more established companies, because of limited product lines and/or operating history, limited financial resources, limited trading markets, and the potential lack of management depth. In addition, the securities of such companies are typically more volatile than securities of larger capitalization companies.

Exchange-Traded Notes Risk is the risk that ETNs in which the Fund may invest are subject to credit risk and the value of an ETN may vary and may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying markets, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events. ETNs are debt securities whose returns are linked to a particular index.

Model Risk is the risk that the models used by the Fund to determine or guide investment decisions may not achieve the objectives of the Fund. Additionally, the portfolio manager of the Fund is able to adjust the models or, under certain adverse conditions, to deviate from the models employed by the Fund. Such adjustments or deviations may not achieve the objectives of the Fund and may produce lower returns and/or higher volatility compared to what the returns and volatility of the Fund would have been if the portfolio manager had not adjusted or deviated from the models.

Non-Diversification Risk is the risk that an investment in the Fund could fluctuate in value more than an investment in a diversified fund. As a non-diversified fund for purposes of the 1940 Act, the Fund may invest a larger portion of its assets in the securities of a few issuers than a diversified fund. A non-diversified fund’s investment in fewer issuers may result in the Fund’s shares being more sensitive to the economic results of those issuers.

Portfolio Turnover Risk is the risk that the Fund’s high portfolio turnover will increase its transaction costs and may result in increased realization of net short-term capital gains (which are taxable to shareholders as ordinary income when distributed to them), higher taxable distributions and lower after-tax performance.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any mutual fund, there is no guarantee that the Fund will achieve its goal.

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

Under normal market conditions, the Fund seeks to achieve its objective by investing directly and indirectly (e.g., through investments in derivatives or other pooled investment vehicles, such as exchange-traded funds and master limited partnerships) at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies principally engaged in the design, development, production, sale, management or distribution of products, services or facilities used for or in connection with oil, gas or power (including natural gas, coal, hydro-power, nuclear power and alternative fuels such as wind, solar and biofuels) (“Energy Companies”) or companies principally engaged in the discovery, development and processing of raw materials (including basic materials, such as metals, minerals and chemicals, which are used as inputs to manufacture other intermediate and finished products) (“Material Companies”). The Fund considers a company “principally engaged” in the Energy or Materials industry if (i) it derives at least 50% of its revenues or profits from goods produced or sold, investments made or services performed in the Energy or Materials industry, or (ii) at least 50% of its assets are devoted to such activities. The Fund generally will take long and short positions in securities of Energy or Material Companies and will vary the Fund’s long-short exposure over time based on its assessment of market conditions and other factors.

The Fund intends to invest primarily in common stocks, senior loans, preferred stocks, warrants, convertible securities, subordinated debt securities and other securities issued by Energy and Material Companies. The Fund also may invest up to (but not including) 25% of the value of its total assets in securities of master limited partnerships (or “MLPs”) in the Energy industry. MLPs typically are engaged in one or more aspects of the exploration, production, processing, transmission, marketing, storage or delivery of energy-related commodities, such as natural gas, natural gas liquids, coal, crude oil or refined petroleum products.

In addition, the Fund may invest up to 20% of the value of its total assets in a wide variety of securities and financial instruments, of all kinds and descriptions, issued by non-Energy or Material Companies. The Fund may invest without limitation in Exchange Traded Funds (“ETFs”) and may invest up to 20% of the value of its total assets in ETFs issued by non-Energy or Material Companies. The Fund’s investments in ETFs and other types of pooled investment vehicles which invest in Energy Companies are intended to provide substantially similar economic exposure to direct investments in these companies. The Fund may invest in securities of issuers of any market capitalization. The Fund may invest in securities of any credit quality.

The Fund may invest up to 50% of the value of its total assets in securities of non-U.S. issuers, which may include, without limitation, emerging market issuers. Such securities may be denominated in U.S. dollars, non-U.S. currencies or multinational currency units (such as the Euro).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use derivatives, primarily options and foreign currency transactions (e.g., foreign currency swaps, futures, and forwards), as tools in the management of portfolio assets. The Fund may also use such derivatives to hedge various investments for risk management and for speculative purposes.

The Fund may borrow an amount up to 33 1/3% (or such other percentage permitted by law) of its total assets (including the amount borrowed) less all liabilities other than borrowings. The Fund may borrow for investment purposes, to meet redemption requests and for temporary, extraordinary or emergency purposes. The use of borrowing for investment purposes (i.e., leverage) increases both investment opportunity and investment risk. However, the Fund has no present intention to use borrowing for investment purposes.

The Fund’s investment strategy utilizes the analytical models of Highland Capital Management, L.P. (“HCM”), sub-adviser of the Fund, to evaluate long and short securities of Energy and Material Companies of varying market capitalizations and seeks to identify those securities HCM believes have the greatest potential for total return. HCM also seeks to take advantage of temporary market inefficiencies in order to boost the overall performance of the Fund.

Long Positions. In selecting investments for long positions of the Fund, HCM focuses on issuers that it believes: (i) have strong cash flow and pay regular dividends; (ii) have potential for long-term earnings per share growth; (iii) may be subject to a value catalyst, such as industry developments, regulatory changes, changes in management, sale or spin-off of a division or the development of a profitable new business; (iv) are well-managed; (v) will benefit from favorable demand and supply dynamics for its products and services; (vi) are best in class, e.g., lowest cost producer; and (vii) are underappreciated by market analysts. HCM will typically focus on companies that are exhibiting one or more of these indicators. Technical analysis may also be used to help in the decision making process.

Short Sales. HCM may sell short securities of a company that it believes: (i) is overvalued relative to normalized business and industry fundamentals or to the expected growth that HCM believes the company will achieve; (ii) has a weak competitive position relative to peers; (iii) engages in questionable accounting practices; (iv) shows declining cash flow and/or liquidity; (v) has earnings estimates which HCM believes are too high; (vi) has weak competitive barriers to entry; (vii) suffers from deteriorating industry and/or business fundamentals; (viii) has a weak management team; (ix) will see multiple contraction; (x) is not adapting to changes in technological, regulatory or competitive environments; or (xi) provides a hedge against the Fund’s long exposure, such as a broad based market ETF. Technical analysis may be used to help in the decision making process. The Fund may engage in short sales that are not made “against-the-box,” which means that the Fund may sell short securities even when they are not actually owned or otherwise covered at all times during the period the short position is open. Short sales that are not made “against-the-box” could result in unlimited loss.

Investment Identification. HCM generates investment ideas from a variety of different sources. These include, but are not limited to, screening software that analyzes both fundamental and technical factors, industry contacts, consultants, company press releases, company conference calls, conversations with company management teams, buy-side contacts, sell-side contacts, brokers, third-party research, independent research of financial and corporate information, third-party research databases, and news services. HCM will make investment decisions based on its analysis of the security’s value, and will also take into account its view of macroeconomic conditions and industry trends. HCM will make investments without regard to a company’s level of capitalization or the tax consequences of the investment (short or long term capital gains).

Portfolio Evaluation. Once an investment opportunity is determined to be attractive as a stand-alone investment, HCM will evaluate the effect of adding that investment to the Fund’s portfolio. In doing so, HCM may seek to minimize the market-related portfolio volatility as well as the risk of a capital loss by hedging such risks primarily through the use of options and other derivatives.

The Fund is non-diversified as defined in the Investment Company Act of 1940, as amended, (the “1940 Act”) but it will adhere to the diversification requirements applicable to regulated investment companies (“RICs”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), which generally are less stringent than those under the 1940 Act. The Fund is not intended to be a complete investment program.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration Under normal market conditions, the Fund seeks to achieve its objective by investing directly and indirectly (e.g., through investments in derivatives or other pooled investment vehicles, such as exchange-traded funds and master limited partnerships) at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies principally engaged in the design, development, production, sale, management or distribution of products, services or facilities used for or in connection with oil, gas or power (including natural gas, coal, hydro-power, nuclear power and alternative fuels such as wind, solar and biofuels) (“Energy Companies”) or companies principally engaged in the discovery, development and processing of raw materials (including basic materials, such as metals, minerals and chemicals, which are used as inputs to manufacture other intermediate and finished products) (“Material Companies”).

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Industry Concentration Risk is the risk that the Fund may be particularly susceptible to economic, political or regulatory events affecting those industries in which the Fund focuses its investments. Because the Fund normally invests at least 80% of the value of its assets in Energy and Material Companies, the Fund’s performance largely depends on the overall condition of these industries and the Fund is susceptible to economic, political and regulatory risks or other occurrences associated with these industries. The Energy and Materials industries may be adversely affected by foreign government, federal or state regulations on energy production, distribution and sale. Stock prices of companies in energy-related industries are also affected by supply and demand both for their specific product or service and for energy products in general.

Equity Securities Risk is the risk that stock prices will fall over short or long periods of time. In addition, common stocks represent a share of ownership in a company, and rank after bonds and preferred stock in their claim on the company’s assets in the event of bankruptcy.

Short Sales Risk is the risk of loss associated with any appreciation on the price of a security borrowed in connection with a short sale. The Fund may engage in short sales that are not made “against-the-box,” which means that the Fund may sell short securities even when they are not actually owned or otherwise covered at all times during the period the short position is open. Short sales that are not made “against-the-box” theoretically involve unlimited loss potential since the market price of securities sold short may continuously increase.

Derivatives Risk is the risk that an investment in derivatives, such as swaps, options and futures, may not correlate completely to the performance of the underlying securities or index and may be volatile, and may result in a loss greater than the principal amount invested. Equity derivatives may also be subject to liquidity risk, as well as the risk that the derivative is mispriced and that the value established for a derivative may be different than what would be produced through the use of another methodology or if it had been priced using market quotations.

Counterparty Risk is the risk that a counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations.

Leverage Risk is the risk associated with the use of leverage for investment purposes to create opportunities for greater total returns. Leverage may increase the risk of loss, cause fluctuations in the market value of the Fund’s portfolio to have disproportionately large effects or cause the net asset value (“NAV”) of the Fund generally to decline faster than it would otherwise.

Debt Securities Risk is the risk that the issuer of a debt security may fail to pay interest or principal when due, and that changes in market interest rates may reduce the value of debt securities or reduce the Fund’s returns. The Fund may invest in debt securities, principally below investment grade securities, but also including investment grade securities and other debt obligations. The Fund’s investments in high yield debt securities generally subject the Fund to greater risk than investments in securities with higher ratings. Such securities are regarded by the rating organizations as predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation.

Senior Loans Risk is the risk that the issuer or a senior may fail to pay interest or principal when due, and changes in market interest rates may reduce the value of the senior loan or reduce the Fund’s returns. The risks associated with senior loans are similar to the risks of high yield debt securities, although senior loans are typically senior and secured in contrast to below investment grade securities, which are often subordinated and unsecured. Senior loans’ higher standing in an issuer’s capital structure has historically resulted in generally higher recoveries than other below investment grade securities in the event of a corporate reorganization or other restructuring. Senior loans and other debt securities are also subject to the risk of price declines and to increases in prevailing interest rates, although, because their interest rates are adjusted for changes in short-term interest rates, senior loans generally have less interest rate risk than other high yield investments, which typically pay fixed rates of interest. The Fund’s investments in senior loans are typically below investment grade and are considered speculative because of the credit risk of their issuers.

Mid-Cap Company Risk is the risk of investing in securities of mid-cap companies that could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Small-Cap Company Risk is the risk that investing in the securities of small-cap companies either directly or indirectly through investments in Underlying Funds may pose greater market and liquidity risks than larger, more established companies, because of limited product lines and/or operating history, limited financial resources, limited trading markets, and the potential lack of management depth. In addition, the securities of such companies are typically more volatile than securities of larger capitalization companies.

Foreign Investment Risk is the risk that investing in foreign (non-U.S.) securities either directly or indirectly may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid. These risks may be heightened for emerging markets securities.

Currency Risk is the risk that fluctuation in exchange rates will adversely affect the value of the Fund’s foreign currency holdings and investments denominated in foreign currencies.

Hedging Risk is the risk that, although intended to limit or reduce investment risk, hedging strategies may also limit or reduce the potential for profit. There is no assurance that hedging strategies will be successful.

Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. The Fund’s share price will fluctuate with changes in the market value of its portfolio securities. Many factors can affect this value and you may lose money by investing in the Fund.

Emerging Markets Risk is the risk of investing in securities of companies located in emerging market countries, which primarily includes increased foreign investment risk. Emerging markets countries may have unstable governments and/or economies that are subject to sudden change, and may also lack the legal, business and social framework to support securities markets, which tends to make investments less liquid and more volatile.

Portfolio Turnover Risk is the risk that the Fund’s high portfolio turnover will increase its transaction costs and may result in increased realization of net short-term capital gains (which are taxable to shareholders as ordinary income when distributed to them), higher taxable distributions and lower after-tax performance.

Fixed Income Securities Risk is the risk that fixed income securities will decline in value because of changes in interest rates. The value of fixed income securities typically changes as interest rates fluctuate. During periods of rising interest rates, fixed income securities generally decline in value. Conversely, during periods of falling interest rates, fixed income securities generally rise in value. This kind of market risk is generally greater for a fund investing in fixed income securities with longer durations.

Credit Risk is the risk that the Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

MLP Risk is the risk holders of units issued by a MLP are exposed to a remote possibility of liability for all of the obligations of that MLP. The Fund may invest in MLP units. An investment in MLP units involves some risks which differ from an investment in the equity securities of a company. Holders of MLP units have limited control and voting rights on matters affecting the partnership. Holders of units issued by a MLP are exposed to a remote possibility of liability for all of the obligations of that MLP in the event that a court determines that the rights of the holders of MLP units to vote to remove or replace the general partner of that MLP, to approve amendments to that MLP’s partnership agreement, or to take other action under the partnership agreement of that MLP would constitute “control” of the business of that MLP, or a court or governmental agency determines that the MLP is conducting business in a state without complying with the partnership statute of that state. Holders of MLP units are also exposed to the risk that they will be required to repay amounts to the MLP that are wrongfully distributed to them. In addition, the value of our investment in an MLP will depend largely on the MLP’s treatment as a partnership for U.S. federal income tax purposes. If an MLP does not meet current legal requirements to maintain partnership status, or if it is unable to do so because of tax law changes, it would be treated as a corporation for U.S. federal income tax purposes. In that case, the MLP would be obligated to pay income tax at the entity level and distributions received by us generally would be taxed as dividend income. As a result, there could be a material reduction in our cash flow from MLP unit investments.

• MLP Common Units. MLP common units can be affected by macro-economic and other factors affecting the stock market in general, expectations of interest rates, investor sentiment toward MLPs or the energy sector, changes in a particular issuer’s financial condition, or unfavorable or unanticipated poor performance of a particular issuer (generally measured in terms of distributable cash flow). Prices of common units of individual MLPs also can be affected by fundamentals unique to the partnership, including earnings power and coverage ratios.

• MLP I-Shares. MLP I-Shares represent an ownership interest issued by an MLP affiliate, typically an LLC, which owns an interest in and manages the MLP. MLP I-Shares may be subject to liquidity risk because of their potentially relatively smaller size. I-Shares may trade at a discount to their related MLP units, despite having an economic value equivalent to an MLP unit and an equal claim on the cash flows underlying the investment.

Tax Status Risk is the risk that the Fund’s ability to invest in certain commodity-related instruments, including in MLPs and ETFs that invest in commodities or commodity-related derivatives, is limited by the Fund’s intention to qualify as a RIC under the Code, and, if the Fund does not appropriately limit such investments or if such investments (or the income earned on such investments) were to be recharacterized for U.S. tax purposes, the Fund could fail to qualify as a RIC under one or more of the qualification tests applicable to RICs under the Code. If the Fund were to fail to qualify as a RIC in any taxable year, and were ineligible to or otherwise did not cure such failure, the Fund would be subject to tax on its taxable income at corporate rates, and all distributions from earnings and profits, including any distributions of net long-term capital gains, would be taxable to shareholders as dividend income. See “Taxation” below.

Exchange-Traded Funds Risk is the risk that the ETFs in which the Fund invests will not be able to replicate exactly the performance of the indices they track and may result in a loss. In addition, shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company when the Fund invests in shares of another investment company.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Illiquid and Restricted Securities Risk is the risk that the Adviser or Sub-Adviser, as applicable, may not be able to sell illiquid or restricted securities at the price it would like or may have to sell them at a loss. Securities of non-U.S. issuers, and emerging markets securities in particular, are subject to illiquidity risk.

Legislation Risk is the risk that to the extent that state, federal or international regulators impose additional requirements or restrictions with respect to Energy and Materials Companies, the availability of such investments may be adversely affected.

Management Risk is the risk that the Adviser or Sub-Adviser may be incorrect in its assessment of the intrinsic value of the securities the Fund holds which may result in a decline in the value of Fund shares and failure to achieve its investment objective. The Fund’s portfolio managers use quantitative analyses and/or models. Any imperfections or limitations in such analyses and models could affect the ability of the portfolio managers to implement strategies.

Non-Diversification Risk is the risk that an investment in the Fund could fluctuate in value more than an investment in a diversified fund. As a non-diversified fund for purposes of the 1940 Act, the Fund may invest a larger portion of its assets in the securities of a few issuers than a diversified fund. A non-diversified fund’s investment in fewer issuers may result in the Fund’s shares being more sensitive to the economic results of those issuers.

Market Disruption Risk is the risk of unusual and extreme volatility in the equity and debt markets and in the prices of individual investments resulting from a period of acute stress recently experienced by domestic and international markets starting in the real estate and financial sectors and then moving to other sectors of the world economy. These market conditions could add to the risk of short-term volatility of the Fund.

Non-Payment Risk is the risk of non-payment of scheduled interest and/or principal with respect to debt securities. Non-payment would result in a reduction of income to the Fund, a reduction in the value of the obligation experiencing non-payment and a potential decrease in the NAV of the Fund.

Prepayment Risk is the risk that part or all of the principal of a debt security will be paid prior to the scheduled maturity. Pursuant to the relevant debt agreement, a borrower may be required, and may have the option at any time, to prepay the principal amount of a debt security, in some instances without incurring a prepayment penalty. In the event that like-yielding debt is not available in the marketplace, the prepayment of and subsequent reinvestment by the Fund in high yield debt could have a materially adverse affect on the yield of the Fund’s investment portfolio. Prepayments may have a beneficial impact on income due to receipt of prepayment penalties, if any, and any facility fees earned in connection with reinvestment.

Risk of Restrictions on Resale is the risk that the Fund’s investments may be subject to restrictions on the type of sale allowed or may otherwise not be readily marketable. Senior loans may not be readily marketable and may be subject to restrictions on resale. As a result, the ability of the Fund to dispose of its investments in a timely fashion and at an advantageous price may be restricted.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Despite gains in some markets after steep declines during certain periods of 2008-2009, negative conditions and price declines may return unexpectedly and dramatically. In addition, the Fund could experience a loss when selling securities in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities sold.

Limited Information Risk is the risk associated with investing in funds for which there is limited historical and financial information available. The types of senior loans in which the Fund will invest historically have not been rated by a nationally recognized statistical rating organization (“NRSRO”), have not been registered with the SEC or any state securities commission, and have not been listed on any national securities exchange. Although the Fund will generally have access to financial and other information made available to the lenders in connection with senior loans, the amount of public information available with respect to senior loans will generally be less extensive than that available for rated, registered or exchange-listed securities. As a result, the performance of the Fund and its ability to meet its investment objective is more dependent on the analytical ability of HCM than would be the case for an investment company that invests primarily in rated, registered or exchange-listed securities.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any mutual fund, there is no guarantee that the Fund will achieve its goal.

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 Expense Example, affect the Fund’s performance. During the period February 1, 2011 through September 30, 2011, the Fund had a portfolio turnover rate of 256% (not annualized) of the average value of its portfolio.

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

Under normal market conditions, the Fund is managed based on signals generated by a proprietary model maintained by the Fund’s sub-adviser (the “Model”). The Model is “technically weighted,” which means that it assigns a greater or lesser importance to asset classes based on signals derived from their price trends. For example, an individual asset class (such as stocks, bonds or commodities) may be assigned a heavier weighting in the portfolio based on its price being above its moving average or a lesser weighting if its price is below its moving average. The net effect being that the investment model “switches smartly” in and out of broad asset classes based on their trends, providing investors an active asset allocation fund.

These proprietary, top-down strategies are intended to profit from market trends in both directions, with little regard for the prospects of individual equity or debt securities. Specifically, the portfolio manager will seek to take long positions (i.e., buy securities) during upward trends in certain securities prices and conversely sell and/or take short positions during downward trends in the price of such securities. The portfolio manager seeks to lower overall Fund volatility through diversification of asset classes, as well as the use of cash. Additionally, the portfolio manager’s trend-following methods seek to provide returns which are un-correlated to traditional managers and investment “styles,” such as growth and value.

The Fund primarily invests in exchange traded funds (“ETFs”) which represent these broad asset classes as opposed to securities representing the debt or equity of individual companies. These ETFs invest primarily in (1) U.S. and foreign equity securities; (2) U.S. Government fixed income securities; (3) commodities; and (4) the U.S. dollar. ETFs are investment companies that seek to track the performance of securities indices or baskets of securities. The Fund’s portfolio may include ETFs that invest in both developed and emerging markets in Europe, the Far East, the Middle East, Africa, Australia, Latin America and North America. The Fund may invest up to 100% net long and 50% net short in international ETFs. The Fund also may invest in exchange traded notes (“ETNs”), in much the same manner in which it invests in ETFs. The Fund may also invest directly in the securities which comprise the ETFs and ETNs discussed above, such as individual equities and government obligations, but excluding physical commodities. The Fund’s investments in U.S. fixed income markets may include other investment companies, such as closed-end funds and other open-end mutual funds (together with ETFs, “Underlying Funds”).

The Fund may employ both leveraged investment techniques as well as short positions, which allows the Fund a market exposure which can range from 150% net long (i.e., the Fund has more long (purchased) positions than short (borrowed) positions) to 50% net short (i.e., the Fund has more short (borrowed) positions than long (purchased) positions). Such extremes however, will be uncommon. The Fund may take a “short position” where the portfolio manager believes that the price of a security or value of an index will decline. The Fund may “short” a particular security by borrowing the security and selling it with the intent of later purchasing the security at a lower price. The Fund may also gain short exposure to an index by buying an ETF that has an inverse exposure to the index. The Fund is non-diversified as defined in the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund is not intended to be a complete investment program.

The Fund may use derivatives, primarily swaps, options and futures contracts, as substitutes for securities in which the Fund can invest. The Fund may also use derivatives to an unlimited extent to hedge various investments for risk management and speculative purposes.

In general, under normal market conditions, the portfolio manager makes investment decisions based on signals generated by the Model. Following the Model, the portfolio manager will generally buy investments during upward trends in the price of securities and sell investments or take short positions during downward trends in the price of securities. The portfolio manager also actively employs the use of cash and cash equivalents as a strategic asset class in an attempt to both sidestep market declines as well as lower overall portfolio volatility. During adverse market, economic or political conditions, as defined by the portfolio manager, the portfolio manager may deviate from the Model, including investing up to 100% of the portfolio in cash, cash equivalents, short-term debt securities and/or money market instruments, moving from a long exposure to a short exposure or from a short exposure to a long exposure in the various asset classes, when they feel doing so will help the Fund achieve its objectives of long-term capital appreciation or capital preservation. The sub-adviser may also adjust the Model from time-to-time to change the component constituents of the Model or in an attempt to improve the Model’s ability to implement a trend-following strategy. The Fund is not intended to be a complete investment program.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objectives, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Currency Risk is the risk that fluctuations in exchange rates will adversely affect the value of the Fund’s foreign currency holdings and investments denominated in foreign currencies.

Exchange-Traded Funds Risk is the risk that the ETFs in which the Fund invests will not be able to replicate exactly the performance of the indices they track and may result in a loss. In addition, shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company when the Fund invests in shares of another investment company.

Exchange-Traded Notes Risk is the risk that ETNs in which the Fund may invest are subject to credit risk and the value of an ETN may vary and may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities or other related markets, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events. ETNs are debt securities whose returns are linked to a particular index. The Fund will bear its proportionate share of any fees and expenses borne by the ETN.

Tax Status Risk is the risk that the Fund’s ability to invest in certain commodity-related instruments, including in MLPs and ETFs that invest in commodities or commodity-related derivatives, is limited by the Fund’s intention to qualify as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”), and, if the Fund does not appropriately limit such investments or if such investments (or the income earned on such investments) were to be recharacterized for U.S. tax purposes, the Fund could fail to qualify as a RIC under one or more of the qualification tests applicable to RICs under the Code. If the Fund were to fail to qualify as a RIC in any taxable year, and were ineligible to or otherwise did not cure such failure, the Fund would be subject to tax on its taxable income at corporate rates, and all distributions from earnings and profits, including any distributions of net long-term capital gains, would be taxable to shareholders as dividend income. See “Taxation” below.

Foreign Investment Risk is the risk that investing in foreign (non-U.S.) securities either directly or indirectly through investments in underlying funds may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid. These risks may be heightened for emerging markets securities.

Government Securities Risk is the risk associated with U.S. Government obligations. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the U.S. or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Derivatives Risk is the risk that an investment in derivatives, such as swaps, options and futures, may not correlate completely to the performance of the underlying securities or index and may be volatile, and may result in a loss greater than the principal amount invested. Equity derivatives may also be subject to liquidity risk, as well as the risk that the derivative is mispriced and that the value established for a derivative may be different than what would be produced through the use of another methodology or if it had been priced using market quotations.

Leverage Risk is the risk associated with the use of leverage for investment purposes to create opportunities for greater total returns. Any investment income or gains earned with respect to the amounts borrowed that are in excess of the interest that is due on the borrowing will augment the Fund’s income. Conversely, if the investment performance with respect to the amounts borrowed fails to cover the interest on such borrowings, the value of the Fund’s shares may decrease more quickly than would otherwise be the case, and dividends on Fund shares could be reduced or eliminated. Interest payments and fees incurred in connection with such borrowings will reduce the amount of net income available for payment to Fund shareholders.

Mid-Cap Company Risk is the risk of investing either directly or indirectly through investments in Underlying Funds in securities of mid-cap companies that could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Model Risk is the risk that the Model used by the Fund to determine or guide investment decisions may not achieve the objectives of the Fund. Additionally, the portfolio manager of the Fund is able to adjust the Model or, under certain adverse conditions, to deviate from the Model employed by the Fund. Such adjustments or deviations may not achieve the objectives of the Fund and may produce lower returns and/or higher volatility compared to what the returns and volatility of the Fund would have been if the portfolio manager had not adjusted or deviated from the Model.

Non-Diversification Risk is the risk that an investment in the Fund could fluctuate in value more than an investment in a diversified fund. As a non-diversified fund for purposes of the 1940 Act, the Fund may invest a larger portion of its assets in the securities of a few issuers than a diversified fund. A non-diversified fund’s investment in fewer issuers may result in the Fund’s shares being more sensitive to the economic results of those issuers.

Portfolio Turnover Risk is the risk that the Fund’s high portfolio turnover will increase its transaction costs and may result in increased realization of net short-term capital gains (which are taxable to shareholders as ordinary income when distributed to them), higher taxable distributions and lower after-tax performance.

Securities Market Risk is the risk that the value of securities owned by the Fund either directly or indirectly through investments in underlying funds may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Despite gains in some markets after steep declines during certain periods of 2008-2009, negative conditions and price declines may return unexpectedly and dramatically. In addition, the Fund could experience a loss when selling securities in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities sold.

Short Sales Risk is the risk of loss associated with any appreciation on the price of a security borrowed in connection with a short sale. The Fund may engage in short sales that are not made “against-the-box,” which means that the Fund may sell short securities even when they are not actually owned or otherwise covered at all times during the period the short position is open. Short sales that are not made “against-the-box” theoretically involve unlimited loss potential since the market price of securities sold short may continuously increase.

Small-Cap Company Risk is the risk that investing in the securities of small-cap companies either directly or indirectly through investments in underlying funds may pose greater market and liquidity risks than larger, more established companies, because of limited product lines and/or operating history, limited financial resources, limited trading markets, and the potential lack of management depth. In addition, the securities of such companies are typically more volatile than securities of larger capitalization companies.

Underlying Funds Risk is the risk that ETFs, mutual funds and closed-end funds in which the Fund may invest are subject to investment advisory and other expenses, which will be paid indirectly by the Fund and its shareholders. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in ETFs, mutual funds and closed-end funds and may be higher than other mutual funds that invest directly in stocks and bonds. The closed-end fund shares may differ from their net asset value. Underlying Funds are subject to specific risks, depending on the nature of the fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any mutual fund, there is no guarantee that the Fund will achieve its goal.

Risk Lose Money [Text] rr_RiskLoseMoney When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus Non-Diversification Risk is the risk that an investment in the Fund could fluctuate in value more than an investment in a diversified fund. As a non-diversified fund for purposes of the 1940 Act, the Fund may invest a larger portion of its assets in the securities of a few issuers than a diversified fund. A non-diversified fund’s investment in fewer issuers may result in the Fund’s shares being more sensitive to the economic results of those issuers.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The Fund is a newly created mutual fund that was organized to acquire the assets and liabilities of the Incline Capital Trend Following Fund (the “Predecessor Fund”) in exchange for Class A Shares of the Fund. Accordingly, the Fund is the successor to the Predecessor Fund, and the following information was derived from the performance records of the Predecessor Fund through September 23, 2011. The Fund has substantially similar objectives, strategies and policies as the Predecessor Fund, which was advised by the Fund’s sub-adviser.

The bar chart and the Average Annual Total Returns table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund’s Class A Shares for each full calendar year since the Predecessor Fund’s inception and by showing how the average annual returns for the Fund’s Class A Shares compared to those of a broad-based securities market index. As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. Class C, Class R and Class Y Shares of the Predecessor Fund were not offered, and Class C, Class R and Class Y Shares were not sold, prior to the date of this Prospectus. The returns of Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses. Updated performance information is available by visiting www.pyxisais.com/Funds———Performance or by calling 1-877-665-1287.

After-tax returns in the table above are shown for Class A Shares only and will differ for Class C, Class R and Class Y Shares. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. For example, after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return before taxes and the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

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 the Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 40% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing at least 80% of its net assets under normal circumstances in equity securities of U.S. companies, such as common and preferred stocks. A U.S. company is a company that generates at least 50% of its revenues or profits from business activities in the U.S., or at least 50% of its assets are situated in the U.S., or the principal trading market for its securities is in the U.S.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. The portfolio managers combine various investment management styles, which may include core, growth and value, designed to produce a broadly diversified portfolio. As a result, the portfolio has characteristics similar to the Standard & Poor’s 500 Index (S&P 500® Index), including average market capitalization and dividend yield potential. Stock selection is key to the performance of the Fund.

Through fundamental company research involving analyzing financial statements and other information about a company, the portfolio managers primarily seek to identify securities of large and medium sized companies (meaning companies with a market capitalization of $2 billion or more) with characteristics such as:

• low valuations in relation to their peers, the market, their historical valuation or their growth rate

• financial strength (favorable debt ratios and other financial characteristics)

• high quality management focused on generating shareholder value

The portfolio managers may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The Fund also may invest to a lesser extent in securities of foreign (non-U.S.) issuers and debt securities. The portfolio managers may also invest in various types of derivatives to gain exposure to certain types of securities as an alternative to investing directly in such securities.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Growth Investing Risk is the risk of investing in growth stocks that may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth-oriented funds will typically underperform when value investing is in favor.

Value Investing Risk is the risk of investing in undervalued stocks that may not realize their perceived value for extended periods of time or may never realize their perceived value. Value stocks may respond differently to market and other developments than other types of stocks. Value-oriented funds will typically underperform when growth investing is in favor.

Mid-Cap Company Risk is the risk that investing in the securities of mid-cap companies could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid. These risks may be heightened for emerging markets securities.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Risk Lose Money [Text] rr_RiskLoseMoney When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund.

Bar Chart and Performance Table [Heading] rr_BarChartAndPerformanceTableHeading Performance
Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock The bar chart and the Average Annual Total Returns table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund’s Class A Shares for each full calendar year and by showing how the Fund’s average annual returns compare with the returns of a broad-based securities market index. As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class B, Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses.

Performance Table Narrative rr_PerformanceTableNarrativeTextBlock

After-tax returns in the table above are shown for Class A Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. For example, after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return before taxes and the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objectives by investing at least 80% of its net assets under normal circumstances in domestic equity securities, such as common and preferred stocks.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. The Fund invests primarily in U.S. companies that the portfolio managers believe are undervalued by the market but have solid growth prospects. The portfolio managers employ a relative value approach to identify companies across all economic sectors which are undervalued relative to the market, their peers, their historical valuation or their growth rate. This approach results in a portfolio more broadly diversified across economic sectors and contrasts with other investing approaches that focus on low absolute valuations and often result in a portfolio concentrated in fewer sectors. A company may be undervalued for reasons such as market overreaction to recent company, industry or economic events. In seeking to satisfy the Fund’s investment objective with respect to future income, the portfolio managers will also consider companies that have the potential to pay dividends in the future. Stock selection is key to the performance of the Fund.

The portfolio managers seek to identify securities of companies with characteristics such as:

• low valuations in relation to their peers and the overall market

• the potential for long-term earnings growth

• above-average free cash flow yields

• high quality management focused on generating shareholder value

• financial strength (favorable debt ratios and other financial characteristics)

• attractive upside potential and limited downside risk

• a catalyst such as changing industry fundamentals, introduction of a new product, a company restructuring, or a change in management

The portfolio managers may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The Fund also may invest to a lesser extent in securities of foreign (non-U.S.) issuers and debt securities. The portfolio managers may also invest in various types of derivatives to gain exposure to certain types of securities as an alternative to investing directly in such securities.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Value Investing Risk is the risk of investing in undervalued stocks that may not realize their perceived value for extended periods of time or may never realize their perceived value. Value stocks may respond differently to market and other developments than other types of stocks. Value-oriented funds will typically underperform when growth investing is in favor.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid. These risks may be heightened for emerging markets securities.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any 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 the Average Annual Total Returns table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund’s Class A Shares for each full calendar year and by showing how the Fund’s average annual returns compare with the returns of a broad-based securities market index. As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class B, Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses. Updated performance information is available by visiting www.pyxisais.com/Funds---Performance or by calling 1-877-665-1287.

Performance Table Narrative rr_PerformanceTableNarrativeTextBlock

After-tax returns in the table above are shown for Class A Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. For Example, after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return before taxes and the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

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 the Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance. Since the Fund had not commenced operations as of the most recent fiscal period, it has not yet reported a portfolio turnover rate as of the date of this Prospectus.
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective under normal market conditions by investing, directly and indirectly (e.g., through investments in derivatives or other pooled investment vehicles), at least 80% of its net assets, plus any borrowings for investment purposes, in equity investments that pay or expect to pay dividends. The term “equity investments” refers to direct and indirect investments in common stocks, preferred stocks and convertible securities. The Fund may invest without limitation in equity investments tied economically to any country in the world, including emerging countries.

In addition to dividend-paying equity investments, the Fund may invest up to 20% of its assets, plus any borrowings for investment purposes, in a variety of other instruments including fixed income securities (including “junk bonds”), exchange-traded funds (“ETFs”), exchange-traded notes (“ETNs”), and warrants. The Fund may use derivatives, primarily swaps, options and futures, to an unlimited extent to hedge various investments for risk management and for speculative purposes. The Fund’s investments in derivatives and other types of pooled investment vehicles that invest in equity investments that pay or expect to pay dividends are intended to provide substantially similar economic exposure to direct investments in such dividend-paying equity investments.

The Fund seeks to invest in high-quality, income generating stocks that offer attractive valuations with below-market risk profiles. The Fund may invest in securities of any market capitalization.

In selecting investments for the Fund, Brookmont Capital Management, LLC (“Brookmont”), sub-adviser of the Fund, reviews macroeconomic data to determine the allocation of investments among various economic sectors. Brookmont seeks to avoid making large sector bets or focusing on individual issuers. Instead, investments are made in securities in all ten economic sectors defined by the S&P 500 Index. Once the sector allocations are determined, Brookmont reviews the investment universe and selects investments based on factors such as dividend yield, the issuer’s debt level, projected cash flow, history of dividend increases, and earnings potential.

The Fund is non-diversified as defined in the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund is not intended to be a complete investment program.

The term “equity investments” refers to direct and indirect investments in common stocks, preferred stocks and convertible securities. The Fund may invest without limitation in equity investments tied economically to any country in the world, including emerging countries.
Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Dividend-Paying Stock Risk is the risk that companies that have paid regular dividends to shareholders may decrease or eliminate dividend payments in the future. A decrease in dividend payments by an issuer may result in a decrease in the value of the security held by the Fund or the Fund receiving less income. Additionally, a fund pursuing a dividend-oriented investment strategy may at times underperform other funds that invest more broadly or that have different investment styles.

Equity Securities Risk is the risk that stock prices will fall over short or long periods of time. In addition, common stocks represent a share of ownership in a company, and rank after bonds and preferred stock in their claim on the company’s assets in the event of bankruptcy. The value of equity securities paying dividends at high rates may be more sensitive to changes in interest rates than are other equity securities.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Despite gains in some markets after steep declines during certain periods of 2008-2009, negative conditions and price declines may return unexpectedly and dramatically. In addition, the Fund could experience a loss when selling securities in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities sold.

Mid-Cap Company Risk is the risk of investing in securities of mid-cap companies that could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Small-Cap Company Risk is the risk that investing in the securities of small-cap companies either directly or indirectly through investments in Underlying Funds may pose greater market and liquidity risks than larger, more established companies, because of limited product lines and/or operating history, limited financial resources, limited trading markets, and the potential lack of management depth. In addition, the securities of such companies are typically more volatile than securities of larger capitalization companies.

Foreign Investment Risk is the risk that investing in foreign (non-U.S.) securities either directly or indirectly may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid. These risks may be heightened for emerging markets securities.

Currency Risk is the risk that fluctuations in exchange rates will adversely affect the value of the Funds foreign currency holdings and investments denominated in foreign currencies.

Derivatives Risk is the risk that an investment in derivatives, such as swaps, options and futures, may not correlate completely to the performance of the underlying securities or index and may be volatile, and may result in a loss greater than the principal amount invested. Equity derivatives may also be subject to liquidity risk, as well as the risk that the derivative is mispriced and that the value established for a derivative may be different than what would be produced through the use of another methodology or if it had been priced using market quotations.

Exchange-Traded Funds Risk is the risk that the ETFs in which the Fund invests will not be able to replicate exactly the performance of the indices they track and may result in a loss. In addition, shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company when the Fund invests in shares of another investment company.

Exchange-Traded Notes Risk is the risk that ETNs in which the Fund may invest are subject to credit risk and the value of an ETN may vary and may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities or other related markets, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events. ETNs are debt securities whose returns are linked to a particular index. The Fund will bear its proportionate share of any fees and expenses borne by the ETN.

Counterparty Risk is the risk that a counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations.

Hedging Risk is the risk that, although intended to limit or reduce investment risk, hedging strategies may also limit or reduce the potential for profit. There is no assurance that hedging strategies will be successful.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

High Yield Securities Risk is the risk that high yield securities or unrated securities of similar credit quality (commonly known as “junk bonds”) are more likely to default than high rated securities. High Yield securities are regarded as speculative with respect to the issuer’s capacity to pay interest and repay principal. The market value of these securities is more sensitive to corporate developments and economic conditions and can be volatile. Market conditions can diminish liquidity and make accurate valuations difficult to obtain.

Management Risk is the risk that the Adviser or Brookmont may be incorrect in its assessment of the intrinsic value of the securities the Fund holds which may result in a decline in the value of Fund shares and failure to achieve its investment objective. The Fund’s portfolio manager uses qualitative analyses and/or models. Any imperfections or limitations in such analyses and models could affect the ability of the portfolio managers to implement strategies.

Non-Diversification Risk is the risk that an investment in the Fund could fluctuate in value more than an investment in a diversified fund. As a non-diversified fund for purposes of the 1940 Act, the Fund may invest a larger portion of its assets in the securities of a few issuers than a diversified fund. A non-diversified fund’s investment in fewer issuers may result in the Fund’s shares being more sensitive to the economic results of those issuers.

Portfolio Turnover Risk is the risk that the Fund’s high portfolio turnover will increase its transaction costs and may result in increased realization of net short-term capital gains (which are taxable to shareholders as ordinary income when distributed to them), higher taxable distributions and lower after-tax performance.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any mutual fund, there is no guarantee that the Fund will achieve its goal.

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 the Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

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

The Fund seeks to achieve its investment objectives by investing at least 80% of its net assets under normal circumstances in equity securities, such as common and preferred stocks.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. The Fund invests primarily in a limited number of large- and medium-sized companies (meaning companies with a market capitalization of $2 billion or more) that the portfolio manager believes have above-average growth histories and/or growth potential. The portfolio manager selects equity securities from a number of industries based on the merits of individual companies. In seeking to satisfy the Fund’s investment objective with respect to future income, the portfolio manager will also consider companies that have the potential to pay dividends in the future, based on factors such as the potential to increase income or free cash flow. Stock selection is key to the performance of the Fund.

The portfolio manager seeks to identify securities of companies with characteristics such as:

• above-average annual growth rates

• financial strength (favorable debt ratios and other financial characteristics)

• leadership in their respective industries

• high quality management focused on generating shareholder value

The portfolio manager may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The Fund also may invest to a lesser extent in securities of foreign (non-U.S.) issuers and debt securities. The portfolio manager may also invest in various types of derivatives to gain exposure to certain types of securities as an alternative to investing directly in such securities.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Growth Investing Risk is the risk of investing in growth stocks that may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth-oriented funds will typically underperform when value investing is in favor.

Mid-Cap Company Risk is the risk of investing in securities of mid-cap companies that could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

After-tax returns in the table above are shown for Class A Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. For example, after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return before taxes and the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

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 the Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 71% of the average value of its portfolio.

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

The Fund seeks to achieve its investment objective by investing at least 80% of its net assets under normal circumstances in equity securities, such as common and preferred stocks, of small-cap companies.

The Fund uses a multi-sub-adviser investment strategy that combines growth, value and core investment management styles. The investment adviser will allocate the Fund’s assets among the sub-advisers to maintain a combination of investment styles, but may have larger allocations to certain sub-advisers based on its assessment of the potential for better performance or to address capacity constraints of a particular sub-adviser, among other reasons. As a result, this orientation will typically produce a portfolio that does not materially favor value or growth style investing, and allows the Fund to benefit from both value and growth cycles in the marketplace. The Fund defines a small-cap company as one with a market capitalization that falls between (a) the bottom range of the Russell 2000® Index (“Russell 2000 Index”) and (b) the greater of either the top range of the Russell 2000 Index or $3.0 billion. As of May 31, 2011, the market capitalization of companies in the Russell 2000 Index ranged from $130 million to $2.97 billion.* The portfolio managers will not sell a stock merely because the market capitalization of a company in the portfolio moves outside its capitalization range or because the index capitalization range changes. Stock selection is key to the performance of the Fund.

The portfolio managers seek to identify securities of companies with characteristics such as:

• high quality management focused on generating shareholder value

• attractive products or services

• appropriate capital structure

• strong competitive positions in their industries

* The Russell 2000 Index is constructed to provide an unbiased small-cap barometer and is reconstituted annually. The capitalization range, however, may change significantly intra-year due to changes in the market capitalization of securities in the Index.

The portfolio managers may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

In addition, the portfolio managers of a sub-adviser with a value management style generally will seek to identify securities of companies with characteristics such as attractive valuation, while portfolio managers of a sub-adviser with a growth management style generally will seek to identify securities of companies with strong growth potential.

The Fund also may invest to a lesser extent in securities with capitalizations outside the Fund’s small-cap range, debt securities and foreign (non-U.S.) securities. The portfolio managers may also invest in index futures, options on index futures and index options to gain exposure to certain types of securities as a substitute to investing directly in such securities. The Fund is not intended to be a complete investment program.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Small-Cap Company Risk is the risk that investing in the securities of small-cap companies may pose greater market and liquidity risks than larger, more established companies, because of limited product lines and/or operating history, limited financial resources, limited trading markets, and the potential lack of management depth. In addition, the securities of such companies are typically more volatile than securities of larger capitalization companies.

Growth Investing Risk is the risk of investing in growth stocks that may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth-oriented funds will typically underperform when value investing is in favor.

Value Investing Risk is the risk of investing in undervalued stocks that may not realize their perceived value for extended periods of time or may never realize their perceived value. Value stocks may respond differently to market and other developments than other types of stocks. Value-oriented funds will typically underperform when growth investing is in favor.

Allocation Risk is the risk that Pyxis Capital, L.P., the Fund’s investment adviser, may not allocate assets of the Fund among investment management styles in an optimal manner, if, among other reasons, it does not correctly assess the attractiveness of an investment style.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class B, Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses.

Performance Table Narrative rr_PerformanceTableNarrativeTextBlock

After-tax returns in the table above are shown for Class A Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. For example, after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return before taxes and the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing at least 80% of its net assets under normal circumstances in equity securities, such as common and preferred stocks.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. The Fund invests in companies in both developed and emerging market countries, including the United States, but will invest at least 25% of its total assets in non-U.S. issuers. The portfolio managers focus on companies that they expect will grow faster than their relevant peers/markets and whose security prices do not fully reflect their potential for growth. When valuations are low, the portfolio managers may also invest in companies that are not expected to grow faster than their relevant peers/markets. Under normal circumstances, the Fund’s assets are invested primarily in countries included in the Morgan Stanley Capital InternationalSM (MSCI®) World Index (“MSCI® World Index”) and in no fewer than three different countries. As of December 31, 2011, U.S. companies represented 52.7% of the MSCI® World Index, but the portion of the Fund’s portfolio represented by U.S. companies may vary materially from that level. Stock selection is key to the performance of the Fund.

The portfolio managers seek to identify securities of growth companies with the following characteristics:

• low prices relative to their long-term cash earnings potential

• potential for significant improvement in the company’s business

• financial strength (favorable debt ratios and other financial characteristics)

• sufficient liquidity

The portfolio managers may consider selling a security when one or more of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The Fund also may invest to a lesser extent in debt securities. The portfolio managers may also invest in various types of derivatives to gain exposure to certain types of securities as an alternative to investing directly in such securities.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S., and investments may be less liquid. These risks may be heightened for emerging markets securities.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

Growth Investing Risk is the risk of investing in growth stocks that may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth-oriented funds will typically underperform when value investing is in favor.

Mid-Cap Company Risk is the risk of investing in securities of mid-cap companies that could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Emerging Markets Risk is the risk of investing in securities of companies located in emerging market countries, which primarily includes increased foreign investment risk. Emerging markets countries may have unstable governments and/or economies that are subject to sudden change, and may also lack the legal, business and social framework to support securities markets, which tends to make investments less liquid and more volatile.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any 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 the Average Annual Total Returns table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund’s Class A Shares for each full calendar year and by showing how the Fund’s average annual returns compare with the returns of a broad-based securities market index. As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class B, Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses.

Performance Table Narrative rr_PerformanceTableNarrativeTextBlock

After-tax returns in the table above are shown for Class A Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. For example, after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return before taxes and the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

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 the Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing at least 80% of its net assets under normal circumstances in equity securities, such as common and preferred stocks.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. The Fund invests primarily (meaning at least 65%) in companies in both developed and emerging market countries outside the U.S. An issuer is considered to be located outside the U.S. if at least 50% of its revenues or profits are from business activities located outside the U.S., or at least 50% of its assets are located outside the U.S., or the principal trading market for its securities is located outside the U.S. The portfolio managers focus on companies whose security prices do not fully reflect their potential for growth. Under normal circumstances, the Fund’s assets are invested in securities of foreign (non-U.S.) companies representing at least three different countries. Stock selection is key to the performance of the Fund.

The portfolio managers seek to identify securities of companies with characteristics such as:

• low valuation relative to their long term cash earnings potential

• potential for significant improvement in the company’s business

• financial strength (favorable debt ratios and other financial characteristics)

• sufficient liquidity

• large or medium capitalization (meaning a market capitalization of $2 billion or more)

The portfolio managers may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The Fund also may invest to a lesser extent in debt securities and may invest in securities of companies located in the U.S. The portfolio managers may also invest in various types of derivatives to gain exposure to certain types of securities as an alternative to investing directly in such securities.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S., and investments may be less liquid.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

Growth Investing Risk is the risk of investing in growth stocks that may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth-oriented funds will typically underperform when value investing is in favor.

Mid-Cap Company Risk is the risk of investing in securities of mid-cap companies that could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Emerging Markets Risk is the risk of investing in securities of companies located in emerging market countries, which primarily includes increased foreign investment risk. Emerging markets countries may have unstable governments and/or economies that are subject to sudden change, and may also lack the legal, business and social framework to support securities markets, which tends to make investments less liquid and more volatile.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.
Risk Lose Money [Text] rr_RiskLoseMoney When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock The bar chart and the Average Annual Total Returns table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund’s Class A Shares for each full calendar year and by showing how the Fund’s average annual returns compare with the returns of a broad-based securities market index. As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class B, Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses.

Performance Table Narrative rr_PerformanceTableNarrativeTextBlock

After-tax returns in the table above are shown for Class A Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. For example, after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return before taxes and the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

The Fund seeks to achieve its investment objective by investing at least 80% of its net assets under normal circumstances in debt securities.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. The Fund invests primarily in a variety of investment-grade debt securities, such as mortgage-backed securities, corporate bonds, U.S. Government securities and money market instruments. The Fund normally has a weighted average maturity of approximately five to ten years, but is subject to no limitation with respect to the maturities of the instruments in which it may invest.

U.S. Government securities are securities that are issued or guaranteed as to principal and interest by the U.S. Government or one of its agencies or instrumentalities. Some U.S. Government securities are backed by the full faith and credit of the U.S. Government, such as U.S. Treasury bills and notes and obligations of the Government National Mortgage Association (Ginnie Mae). Other U.S. Government securities are backed by the issuer’s right to borrow from the U.S. Treasury, such as Federal National Mortgage Association (Fannie Mae) securities, while some are backed only by the credit of the issuing organization, such as obligations of the Federal Home Loan Mortgage Corporation (Freddie Mac).

The portfolio managers seek to identify debt securities with characteristics such as:

• attractive yields and prices

• the potential for capital appreciation

• reasonable credit quality

The portfolio managers may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The Fund also may invest to a lesser extent in asset-backed securities, high yield securities (also known as “junk bonds”), foreign (non-U.S.) debt securities and equity securities, such as exchange traded funds.

The portfolio managers may also invest in various types of derivatives to manage interest rate risk (also known as duration) and to manage exposure to credit quality.

Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund seeks to achieve its investment objective by investing at least 80% of its net assets under normal circumstances in debt securities.
Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Prepayment Risk is the risk that during periods of falling interest rates, issuers of debt securities may repay higher rate securities before their maturity dates. This may cause the Fund to lose potential price appreciation and to be forced to reinvest the unanticipated proceeds at lower interest rates.

Mortgaged-Backed Securities Risk is the risk of investing in mortgaged-backed securities, and includes interest rate risk, prepayment risk and the risk that the Fund could lose money if there are defaults on the mortgage loans underlying these securities.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

High Yield Securities Risk is the risk that high yield securities or unrated securities of similar credit quality (commonly known as “junk bonds”) are more likely to default than higher rated securities. The market value of these securities is more sensitive to corporate developments and economic conditions and can be volatile. Market conditions can diminish liquidity and make accurate valuations difficult to obtain.

Asset-Backed Securities Risk is the risk of investing in asset-backed securities, and includes interest rate risk, prepayment risk and the risk that the Fund could lose money if there are defaults on the loans underlying these securities.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any 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 the Average Annual Total Returns table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund’s Class A Shares for each full calendar year and by showing how the Fund’s average annual returns compare with the returns of a broad-based securities market index. As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class B, Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses.

Performance Table Narrative rr_PerformanceTableNarrativeTextBlock

After-tax returns in the table above are shown for Class A Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. For example, after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

The Fund seeks to achieve its investment objective by investing at least 80% of its net assets under normal circumstances in U.S. Government securities.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. The Fund’s investments may also include mortgage-backed securities with remaining maturities of one year or more. The Fund normally has an average duration of approximately three to six years. Portfolio duration is one measure of risk, as noted under “Interest Rate Risk” below.

U.S. Government securities are securities that are issued or guaranteed as to principal and interest by the U.S. Government or one of its agencies or instrumentalities. Some U.S. Government securities are backed by the full faith and credit of the U.S. Government, such as U.S. Treasury bills and notes and obligations of the Government National Mortgage Association (Ginnie Mae). Other U.S. Government securities are backed by the issuer’s right to borrow from the U.S. Treasury, such as Federal National Mortgage Association (Fannie Mae) securities, while some are backed only by the credit of the issuing organization, such as obligations of the Federal Home Loan Mortgage Corporation (Freddie Mac).

The Fund invests in securities issued by:

• the U.S. Treasury

• Government National Mortgage Association (Ginnie Mae)

• Federal National Mortgage Association (Fannie Mae)

• Federal Home Loan Mortgage Corporation (Freddie Mac)

• other U.S. Government agencies and instrumentalities

No more than 20% of the Fund’s assets may be invested in debt securities rated A or lower by Moody’s or S& P or comparably rated by another nationally recognized statistical rating organization, and no more than 10% of the Fund’s assets may be invested in debt securities rated Baa by Moody’s or BBB by S& P or comparably rated by another nationally recognized statistical rating organization.

The portfolio managers seek to identify debt securities with characteristics such as:

• attractive yields and prices

• the potential for capital appreciation

• reasonable credit quality

The portfolio managers may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The Fund also may invest to a lesser extent in a variety of debt securities including corporate debt securities, asset-backed securities and foreign securities. The portfolio managers may also invest in various types of derivatives to manage interest rate exposure (also known as duration).

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Government Securities Risk is the risk associated with U.S. Government obligations. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the U.S. or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Prepayment Risk is the risk that during periods of falling interest rates, issuers of debt securities may repay higher rate securities before their maturity dates. This may cause the Fund to lose potential price appreciation and to be forced to reinvest the unanticipated proceeds at lower interest rates.

Mortgaged-Backed Securities Risk is the risk of investing in mortgaged-backed securities, and includes interest rate risk, prepayment risk and the risk that the Fund could lose money if there are defaults on the mortgage loans underlying these securities.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

Asset-Backed Securities Risk is the risk of investing in asset-backed securities, and includes interest rate risk, prepayment risk and the risk that the Fund could lose money if there are defaults on the loans underlying these securities.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.
Risk Lose Money [Text] rr_RiskLoseMoney When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund.

As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class B Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class A, Class C, Class R and Class Y Shares would have substantially similar returns as Class B because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses.

After-tax returns in the table above are shown for Class B Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

The Fund seeks to achieve its investment objective by investing at least 80% of its net assets under normal circumstances in U.S. Government securities.

Pyxis Capital, L.P. (“Pyxis”) the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. The Fund’s investments may also include mortgage-backed securities and repurchase agreements secured by U.S. Government securities. The Fund normally has a weighted average maturity of not more than three years.

U.S. Government securities are securities that are issued or guaranteed as to principal and interest by the U.S. Government or one of its agencies or instrumentalities. Some U.S. Government securities are backed by the full faith and credit of the U.S. Government, such as U.S. Treasury bills and notes and obligations of the Government National Mortgage Association (Ginnie Mae). Other U.S. Government securities are backed by the issuer’s right to borrow from the U.S. Treasury, such as Federal National Mortgage Association (Fannie Mae) securities, while some are backed only by the credit of the issuing organization, such as obligations of the Federal Home Loan Mortgage Corporation (Freddie Mac).

The Fund invests in securities issued or secured by:

• the U.S. Treasury

• Government National Mortgage Association (Ginnie Mae)

• Federal National Mortgage Association (Fannie Mae)

• Federal Home Loan Mortgage Corporation (Freddie Mac)

• other U.S. Government agencies and instrumentalities

The portfolio managers seek to identify debt securities with characteristics such as:

• attractive yields and prices

• the potential for capital appreciation

• reasonable credit quality

The portfolio managers may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The Fund also may invest to a lesser extent in a variety of debt securities, including corporate bonds, privately issued mortgage-backed securities, asset-backed securities and foreign securities. The portfolio managers may also invest in various types of derivatives to manage interest rate exposure (also known as duration).

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Government Securities Risk is the risk associated with U.S. Government obligations. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the U.S. or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Prepayment Risk is the risk that during periods of falling interest rates, issuers of debt securities may repay higher rate securities before their maturity dates. This may cause the Fund to lose potential price appreciation and to be forced to reinvest the unanticipated proceeds at lower interest rates.

Mortgaged-Backed Securities Risk is the risk of investing in mortgaged-backed securities, and includes interest rate risk, prepayment risk and the risk that the Fund could lose money if there are defaults on the mortgage loans underlying these securities.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S. and investments may be less liquid.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

Asset-Backed Securities Risk is the risk of investing in asset-backed securities, and includes interest rate risk, prepayment risk and the risk that the Fund could lose money if there are defaults on the loans underlying these securities.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Risk Lose Money [Text] rr_RiskLoseMoney When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock The bar chart and the Average Annual Total Returns table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund’s Class A Shares for each full calendar year and by showing how the Fund’s average annual returns compare with the returns of a broad-based securities market index. As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class B, Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses.

Performance Table Narrative rr_PerformanceTableNarrativeTextBlock

After-tax returns in the table above are shown for Class A Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return before taxes and the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

The Fund seeks to achieve its investment objective by investing primarily in investment-grade municipal obligations. Under normal circumstances, the portfolio manager manages the Fund so that at least 80% of the Fund’s income is exempt from both regular federal income taxes and the federal alternative minimum tax.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. The Fund generally will have an effective duration of 75% to 125% of the duration of the Barclays Capital 10-Year Municipal Bond Index. As of December 31, 2011, the effective duration of the Barclays Capital 10-Year Municipal Bond Index was 6.17 years. Portfolio duration is one measure of risk, as noted under “Interest Rate Risk” below.

The portfolio manager seeks to identify municipal obligations with characteristics such as:

• attractive yields and prices

• the potential for income generation

• the potential for capital appreciation

• reasonable credit quality

The portfolio manager may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The Fund also may invest to a lesser extent in tax-free or taxable money market instruments and may hold cash. The portfolio manager may also invest in various types of derivatives to manage interest rate exposure (also known as duration) and to manage exposure to credit quality.

The Fund’s policy that at least 80% of its income be exempt from both regular federal income taxes and the federal alternative minimum tax may only be changed with shareholder approval.

Under normal circumstances, the portfolio manager manages the Fund so that at least 80% of the Fund’s income is exempt from both regular federal income taxes and the federal alternative minimum tax.
Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Municipal Obligations Risk is the risk of investing in municipal securities, and includes interest rate risk and the credit risk of the issuers of municipal securities. The municipal securities market is volatile and may be significantly affected by adverse tax, legislative or political changes. To the extent that the Fund remains relatively small, it may have fewer favorable investment opportunities.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Bar Chart and Performance Table [Heading] rr_BarChartAndPerformanceTableHeading Performance
Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock The bar chart and the Average Annual Total Returns table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund’s Class A Shares for each full calendar year and by showing how the Fund’s average annual returns compare with the returns of a broad-based securities market index. As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class B, Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses.

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 the Annual Fund Operating Expenses or in the Expense Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 177% of the average value of its portfolio.

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

The Fund seeks to achieve its investment objective by investing primarily in a combination of U.S. and foreign equity and debt securities and cash. The Fund’s asset allocation process utilizes information from the Fund’s sub-adviser, GE Asset Management Incorporated (“GEAM”), to diversify holdings across these asset classes. The Fund adjusts its weightings based on market and economic conditions to meet its objectives. The Fund may also invest in various types of derivatives to gain exposure to certain types of securities as an alternative to investing directly in such securities, to manage currency exposure and interest rate exposure (also known as duration), and to manage exposure to credit quality.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GEAM, the Fund’s sub-adviser. The Fund invests in equity securities, such as common and preferred stocks, principally for their capital appreciation potential and investment-grade debt securities principally for their income potential. The Fund invests in cash principally for the preservation of capital, income potential or maintenance of liquidity. Within each asset class, the portfolio managers primarily use active security selection to choose securities based on the perceived merits of individual issuers, although portfolio managers of different asset classes or strategies may place different emphasis on the various characteristics of a company (as identified below) during the selection process.

The portfolio managers seek to identify equity securities of companies with characteristics such as:

• strong earnings growth

• favorable valuation

• a presence in successful industries

• high quality management focused on generating shareholder value

• large or medium capitalization (meaning a market capitalization of $2 billion or more)

The portfolio managers seek to identify debt securities with characteristics such as:

• attractive yields and prices

• the potential for capital appreciation

• reasonable credit quality (typically investment grade debt securities, such as mortgage-backed securities, corporate bonds, U.S. Government securities and money market instruments)

The portfolio managers may consider selling a security when one of these characteristics no longer applies, or when valuation becomes excessive and more attractive alternatives are identified.

The portion of the Fund invested in debt securities normally has a weighted average maturity of approximately five to ten years, but is subject to no limitation with respect to the maturities of the instruments in which it may invest.

The Fund may also invest to a lesser extent in high yield securities (also known as “junk bonds”), equity and debt securities of companies that are located in emerging market countries, and exchange traded funds (ETFs) to gain exposure to securities including those of U.S. issuers that are principally engaged in or related to the real estate industry.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund. No assurance can be given that the Fund will achieve its investment objective, and investment results may vary substantially over time and from period to period. An investment in the Fund is not appropriate for all investors.

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities sold.

Mid-Cap Company Risk is the risk that investing in the securities of mid-cap companies could entail greater risks than investments in larger, more established companies. Mid-cap companies tend to have more narrow product lines, more limited financial resources and a more limited trading market for their stocks, as compared with larger companies. As a result, their stock prices may decline significantly as market conditions change.

Small-Cap Company Risk is the risk that investing in the securities of small-cap companies may pose greater market and liquidity risks than larger, more established companies, because of limited product lines and/or operating history, limited financial resources, limited trading markets, and the potential lack of management depth. In addition, the securities of such companies are typically more volatile than securities of larger capitalization companies.

Growth Investing Risk is the risk of investing in growth stocks that may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth-oriented funds will typically underperform when value investing is in favor.

Value Investing Risk is the risk of investing in undervalued stocks that may not realize their perceived value for extended periods of time or may never realize their perceived value. Value stocks may respond differently to market and other developments than other types of stocks. Value-oriented funds will typically underperform when growth investing is in favor.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S., and investments may be less liquid.

Currency Risk is the risk that the dollar value of foreign investments will change in response to changes in currency exchange rates. If a foreign currency weakens against the U.S. dollar, the U.S. dollar value of an investment denominated in that currency would also decline.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Credit Risk is the risk that the Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Prepayment Risk is the risk that during periods of falling interest rates, issuers of debt securities may repay higher rate securities before their maturity dates. This may cause the Fund to lose potential price appreciation and to be forced to reinvest the unanticipated proceeds at lower interest rates.

Allocation Risk is the risk that Pyxis may not allocate assets of the Fund among strategies or asset classes in an optimal manner, if, among other reasons, it does not correctly assess the attractiveness of a strategy or asset class.

Valuation Risk is the risk that the portfolio securities that have been valued using techniques other than market quotations, may have valuations that are different from those produced using other methodology, and that the security may be sold at a discount to the value established by the Fund.

Illiquid and Restricted Securities Risk is the risk that the Adviser may not be able to sell illiquid or restricted securities at the price it would like or may have to sell them at a loss. Securities of non-U.S. issuers, and emerging markets securities in particular, are subject to illiquidity risk.

High Yield Securities Risk is the risk that high yield securities or unrated securities of similar credit quality (commonly known as “junk bonds”) are more likely to default than higher rated securities. The market value of these securities is more sensitive to corporate developments and economic conditions and can be volatile. Market conditions can diminish liquidity and make accurate valuations difficult to obtain.

Emerging Markets Risk is the risk of investing in securities of companies located in emerging market countries, which primarily includes increased foreign investment risk. Emerging markets countries may have unstable governments and/or economies that are subject to sudden change, and may also lack the legal, business and social framework to support securities markets, which tends to make investments less liquid and more volatile.

REIT-Specific Risk includes the risk that an investment in the stocks of real estate investment trusts (“REITs”) will decline because of adverse developments affecting the real estate industry and real property values. An investment in a REIT also may be adversely affected or lost if the REIT fails to qualify as a REIT for tax purposes.

Real Estate Securities Risk is the risk that an investment in real estate securities will be closely linked to the performance of the real estate markets. Property values or income may fall due to increasing vacancies or declining rents resulting from economic, legal, cultural or technological developments.

Derivatives Risk is a combination of several risks, including the risks that: (1) an investment in a derivative instrument will not correlate well with the performance of the securities or asset class to which the Fund seeks exposure, (2) a derivative instrument entailing leverage may result in a loss greater than the principal amount invested, and (3) derivatives not traded on an exchange may be subject to credit risk, as well as liquidity risk and the related risk that the instrument is difficult or impossible to value accurately. For example, the methodology the Fund uses to establish the fair value of a derivative may result in a value materially different from the value obtained using an alternative methodology.

It is possible to lose money on an investment in the Fund, and this risk of loss may be heightened if you hold shares of the Fund for a shorter period. An investment in the Fund is not a deposit of any 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 the Average Annual Total Returns table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund’s Class A Shares for each full calendar year and by showing how the Fund’s average annual returns compare with the returns of two broad-based securities market indices. As with all mutual funds, the Fund’s past performance (before and after taxes) does not predict how the Fund will perform in the future. The Fund’s performance reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Both the chart and the table assume the reinvestment of dividends and distributions. The bar chart does not reflect the deduction of applicable sales charges for Class A Shares. If sales charges had been reflected, the returns for Class A Shares would be less than those shown below. The returns of Class B, Class C, Class R and Class Y Shares would have substantially similar returns as Class A because the classes are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes have different expenses.

Performance Table Narrative rr_PerformanceTableNarrativeTextBlock

After-tax returns in the table above are shown for Class A Shares only and after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

In some cases, average annual return after taxes on distributions and redemptions is higher than the average annual return before taxes and the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations.

The Fund seeks to achieve its investment objective by investing primarily in short-term, U.S. dollar-denominated money market instruments. The Fund’s investments may include U.S. Government securities, repurchase agreements, commercial paper, certificates of deposit, variable rate securities, asset-backed securities, foreign debt securities, Eurodollar deposits and domestic and foreign bank deposits.

Pyxis Capital, L.P. (“Pyxis”), the Fund’s investment adviser, has allocated all the assets of the Fund to be managed/advised by GE Asset Management Incorporated (“GEAM”), the Fund’s sub-adviser. U.S. Government securities are securities that are issued or guaranteed as to principal and interest by the U.S. Government or one of its agencies or instrumentalities. Some U.S. Government securities are backed by the full faith and credit of the U.S. Government, such as U.S. Treasury bills and notes and obligations of the Government National Mortgage Association (Ginnie Mae). Other U.S. Government securities are backed by the issuer’s right to borrow from the U.S. Treasury, such as Federal National Mortgage Association (Fannie Mae) securities, while some are backed only by the credit of the issuing organization, such as obligations of the Federal Home Loan Mortgage Corporation (Freddie Mac).

The Fund invests consistent with regulatory standards governing security quality, maturity, liquidity and portfolio diversification. For example, the portfolio manager limits investments to high quality securities with remaining maturities of up to 13 months and limits the weighted average maturity of the Fund’s portfolio to 60 days or less. The Fund may invest more than 25% of its total assets in the domestic banking industry. All of the Fund’s assets must be rated in the two highest short-term rating categories (or their unrated equivalents), and at least 97% of its assets must be rated in the highest rating category (or its unrated equivalent), by a nationally recognized statistical rating organization.

The investment adviser may consider the following factors when buying and selling securities for the Fund: (i) portfolio liquidity, (ii) redemption requests, (iii) yield management, and (iv) credit management.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

The principal risks of investing in the Fund are:

Securities Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. A general downturn in the securities market may cause multiple asset classes to decline in value simultaneously, although equity securities generally have greater price volatility than fixed income securities. Negative conditions and price declines may occur unexpectedly and dramatically. In addition, the Fund could be forced to sell portfolio securities at an inopportune time in order to meet unusually large or frequent redemption requests in times of overall market turmoil or declining prices for the securities.

Government Securities Risk is the risk associated with U.S. Government obligations. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the U.S. or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Interest Rate Risk is the risk that fixed income securities will decline in value because of changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

Credit Risk is the risk that the issuer or guarantor of a fixed income security, or the counterparty of a derivatives contract or repurchase agreement, is unable or unwilling (or is perceived to be unable or unwilling) to make timely payment of principal and/or interest, or to otherwise honor its obligations.

Asset-Backed Securities Risk is the risk of investing in asset-backed securities, and includes interest rate risk, prepayment risk and the risk that the Fund could lose money if there are defaults on the loans underlying these securities.

Banking Industry Risk. Adverse changes in economic and regulatory developments affecting the banking industry could affect the ability of the banks to meet their obligations. Such adverse economic changes may include substantial losses on loans, increases in non-performing assets and charge-offs and declines in total deposits. The activities of U.S. banks and most foreign banks are subject to comprehensive regulations which, in the case of U.S. regulations, have undergone substantial changes in the past decade and are currently subject to legislative and regulatory scrutiny. Banks may be particularly susceptible to certain economic factors, such as interest rate changes and adverse developments in the market for real estate. Fiscal and monetary policy and general economic cycles can affect the availability and cost of funds, loan demand and asset quality and thereby impact the earnings and financial conditions of banks.

Foreign Investment Risk is the risk that investing in securities of foreign (non-U.S.) issuers may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, nationalization, expropriation or confiscatory taxation, currency blockages and political changes or diplomatic developments. The costs of investing in many foreign markets are higher than the U.S., and investments may be less liquid.

It is possible to lose money on an investment in the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Although the Fund seeks to maintain a net asset value of $1.00 per share, it is possible to lose money by investing in the Fund. The Fund’s yield will change due to movements in current short-term interest rates and market conditions. A change in interest rates or default on the Fund’s investments could cause the Fund’s share price to decline below $1.00.
