Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund's performance. During the most recent fiscal year, the Predecessor Fund's portfolio turnover rate was 130% of the average value of its portfolio.

Example.
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

•  Your investment has a 5% return each year

•  The Fund's operating expenses remain the same (except that the examples reflect the expense limitation arrangements for only the first year)

•  You reinvest all dividends and distributions

•  You pay any deferred sales charge due for the applicable period.

Your actual costs may be higher or lower. Based on these assumptions, for every $10,000 invested, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

Strategy [Heading] rr_StrategyHeading
PRINCIPAL INVESTMENT STRATEGY.
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks income and capital growth by investing primarily in a diversified portfolio of U.S. and non-U.S. equity and fixed income securities that the Fund's sub-advisers, Schroder Investment Management North America Inc. ("SIMNA") and Schroder Investment Management North America Limited ("SIMNA Ltd.," together with SIMNA, the "Sub-Advisers"), believe offer attractive yields backed by strong fundamentals. The Sub-Advisers actively allocate the Fund's investments among various asset classes, regions, and sectors in response to changing market, economic, and political factors and events that the Sub-Advisers believe may affect the relative levels of income available. The Sub-Advisers also consider the potential for capital growth from investments in the different asset classes, and the risks of investments in those asset classes. The Fund may invest in companies of any size market capitalization.

The Fund invests primarily in securities of issuers located in a number of countries around the world, including emerging markets and the United States. Every asset class is reviewed on an ongoing basis by the Sub-Advisers to determine whether it provides the opportunity to enhance performance or to reduce risk. Exposure to different asset classes and strategies will vary over time, in response to changes in the Sub-Advisers' assessment of changing market, economic, and political factors and events that the Sub-Advisers believe may impact the value of the Fund's investments. The Fund may seek to hedge against adverse changes in the values of the currencies in which its investments are denominated, although it will not be required to do so.

The Fund may invest in fixed income securities to an unlimited extent. Fixed income securities in which the Fund may invest may be obligations of governments or government agencies or instrumentalities, supra-national issuers, or corporate issuers. They may pay fixed, variable, or floating interest rates and may include asset-backed securities, mortgage-backed securities, zero-coupon securities, convertible securities, inflation-indexed bonds, structured notes, bank loans, loan participations, loan assignments, municipal securities, and other securities bearing fixed or variable interest rates of any maturity. The Fund may invest in securities rated in any rating category and in unrated securities, and it may invest any portion of its assets in securities rated below investment grade or in unrated securities considered by the Sub-Advisers to be of comparable quality (so-called "junk bonds").

The investment processes used by the Sub-Advisers may result in frequent trading of the Fund's portfolio securities. The Sub-Advisers may sell an investment for the Fund if they believe that the investment no longer offers attractive potential future returns compared to other investment opportunities or that it presents undesirable risks, or in an attempt to limit losses.

The Fund generally intends to invest in high quality stocks with attractive yield characteristics and sustainable dividend payments to help establish a diversified and liquid portfolio. The Fund may invest in equity securities to an unlimited extent, including common stocks, preferred stocks, securities convertible into common and preferred stock, and non-convertible preferred stocks. The Fund may invest in securities of issuers in their initial public offerings ("IPOs"). In addition to the equity and fixed income investments described above, the Fund may invest in hybrid securities and other alternative investments, such as real estate investment trusts ("REITs") and other property trusts, structured products, and master limited partnerships ("MLPs"). The Sub-Advisers will also invest in cash and cash equivalents strategically, potentially building the Fund's cash position when the advisers believe that attractive investments for the Fund are not available or when the advisers believe that a relatively large cash position will help ensure that the Fund will be able to invest in attractive new opportunities as they become available.
Risk [Heading] rr_RiskHeading
PRINCIPAL RISKS.
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. 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 fund, there is no guarantee that the Fund will achieve its investment objective. For more information regarding risks and investment matters, please see "Additional Information Regarding Investment Strategies and Risks" and "More Information About Risks" in the Fund's statutory prospectus.

Market Risk – Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities may decline in value due to the activities and financial prospects of individual companies or to general market and economic movements and trends, including adverse changes to credit markets.

Equity Risk – The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Mid Cap and Small Cap Securities Risk – Investments in small capitalization and mid capitalization companies involve greater risks than investments in larger, more established companies. Many of these companies are young and have limited operating or business history. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks, include the risks of bankruptcy.

Interest Rate Risk – The risk that your investment may go down in value when interest rates rise, because when interest rates rise, the prices of bonds and fixed rate loans fall. A wide variety of factors can cause interest rates to rise, including central bank monetary policies and inflation rates. Generally, the longer the maturity of a bond or fixed rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund's income. These risks are greater during periods of rising inflation. Volatility in interest rates and in fixed income markets may increase the risk that the Fund's investment in fixed income securities will go down in value. Risks associated with rising interest rates are currently heightened because interest rates in the U.S. are at, or near, historic lows.

Credit Risk – Credit risk is the risk that the issuer of a security or other instrument will not be able to make principal and interest payments when due. Changes in an issuer's financial strength, credit rating or the market's perception of an issuer's creditworthiness may also affect the value of the Fund's investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

High Yield Investments Risk – High yield investments rated below investment grade (also referred to as "junk bonds") are considered to be speculative and are subject to heightened credit risk, which may make the Fund more sensitive to adverse developments in the U.S. and abroad. Lower rated debt securities generally involve greater risk of default or price changes due to changes in the issuer's creditworthiness than higher rated debt securities. The market prices of these securities may fluctuate more than higher quality securities and may decline significantly in periods of general economic difficulty. There may be little trading in the secondary market for particular debt securities, which may make them more difficult to value or sell.

Loans and Loan Participations Risk – Loans and loan participations, including floating rate loans, are subject to credit risk, including the risk of nonpayment of principal or interest. Also, substantial increases in interest rates may cause an increase in loan defaults. Although the loans the Fund holds may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment.

In addition, in the event an issuer becomes insolvent, a loan could be subject to settlement risks or administrative disruptions that could adversely affect the Fund's investment. It may also be difficult to obtain reliable information about a loan or loan participation.

Many loans are relatively illiquid or are subject to restrictions on resale and may be difficult to value, which will have an adverse impact on the Fund's ability to dispose of particular loans or loan participations when necessary to meet redemption requests or liquidity needs, or to respond to a specific economic event, such as deterioration in the creditworthiness of the borrower. Loans may also be subject to extension risk (the risk that borrowers will repay a loan more slowly in periods of rising interest rates) and prepayment risk (the risk that borrowers will repay a loan more quickly in periods of falling interest rates). The Fund may acquire a participation interest in a loan that is held by another party. When the Fund's loan interest is a participation, the Fund may have less control over the exercise of remedies than the party selling the participation interest, and it normally would not have any direct rights against the borrower.

Loan interests may not be considered "securities," and purchasers, such as the Fund, may not, therefore, be entitled to rely on the anti-fraud protections of the federal securities laws. The Fund may be in possession of material non-public information about a borrower or issuer as a result of its ownership of a loan or security of such borrower or issuer. Because of prohibitions on trading in securities of issuers while in possession of such information, the Fund may be unable to enter into a transaction in a loan or security of such a Borrower or issuer when it would otherwise be advantageous to do so.

Foreign Investments Risk – Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions, may affect the value of the Fund's investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund's foreign investments.

Emerging Markets Risk – The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation, less extensive and less frequent accounting, financial and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

Currency Risk – The risk that the value of the Fund's investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer's local currency.

Mortgage- and Asset-Backed Securities Risk – Mortgage- and asset-backed securities represent interests in "pools" of mortgages or other assets, including consumer loans or receivables held in trust. Mortgage-backed securities are subject to credit risk, interest rate risk, "prepayment risk" (the risk that borrowers will repay a loan more quickly in periods of falling interest rates) and "extension risk" (the risk that borrowers will repay a loan more slowly in periods of rising interest rates). If the Fund invests in mortgage-backed or asset-backed securities that are subordinated to other interests in the same mortgage pool, the Fund may only receive payments after the pool's obligations to other investors have been satisfied. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may limit substantially the pool's ability to make payments of principal or interest to the Fund, reducing the values of those securities or in some cases rendering them worthless. The risk of such defaults is generally higher in the case of mortgage pools that include so-called "subprime" mortgages.

Liquidity Risk – The risk that the market for a particular investment or type of investment is or becomes relatively illiquid, making it difficult for the Fund to sell that investment at an advantageous time or price. Illiquidity may be due to events relating to the issuer of the securities, market events, rising interest rates, economic conditions or investor perceptions. Illiquid securities may be difficult to value and their value may be lower than the market price of comparable liquid securities, which would negatively affect the Fund's performance.

Sovereign Debt Risk – Investments in sovereign debt are subject to the risk that the issuer of the non-U.S. sovereign debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay the principal or interest when due. This may result from political or social factors, the general economic environment of a country or economic region, levels of foreign debt or foreign currency exchange rates.

Active Trading Risk – Active trading could increase the Fund's transaction costs and may increase your tax liability as compared to a fund with less active trading policies. These effects may adversely affect Fund performance.

Volatility Risk – Share price, yield and total return may fluctuate more than with funds that use a different investment strategy.

Leverage Risk – Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly. Leverage may also cause the Fund to be more volatile than if it had not been leveraged. The use of leverage may cause the Fund to liquidate portfolio positions to satisfy its obligations or to meet asset segregation requirements when it may not be advantageous to do so.

Investment Strategy Risk – The risk that, if the Sub-Advisers' investment strategy does not perform as expected, the Fund could underperform its peers or lose money. There is no guarantee that the Fund's investment objective will be achieved.

Large Shareholder Transaction Risk – The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund's net asset value ("NAV") and liquidity. Similarly, large Fund share purchases may adversely affect a Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks, which are discussed in "Additional Information Regarding Investment Strategies and Risks" and "More Information About Risks" in the Fund's statutory prospectus.

Portfolio Turnover.
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund's performance. During the most recent fiscal year, the Predecessor Fund's portfolio turnover rate was 130% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

•  Your investment has a 5% return each year

•  The Fund's operating expenses remain the same (except that the examples reflect the expense limitation arrangements for only the first year)

•  You reinvest all dividends and distributions

•  You pay any deferred sales charge due for the applicable period.

Your actual costs may be higher or lower. Based on these assumptions, for every $10,000 invested, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

Strategy [Heading] rr_StrategyHeading
PRINCIPAL INVESTMENT STRATEGY.
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks income and capital growth by investing primarily in a diversified portfolio of U.S. and non-U.S. equity and fixed income securities that the Fund's sub-advisers, Schroder Investment Management North America Inc. ("SIMNA") and Schroder Investment Management North America Limited ("SIMNA Ltd.," together with SIMNA, the "Sub-Advisers"), believe offer attractive yields backed by strong fundamentals. The Sub-Advisers actively allocate the Fund's investments among various asset classes, regions, and sectors in response to changing market, economic, and political factors and events that the Sub-Advisers believe may affect the relative levels of income available. The Sub-Advisers also consider the potential for capital growth from investments in the different asset classes, and the risks of investments in those asset classes. The Fund may invest in companies of any size market capitalization.

The Fund invests primarily in securities of issuers located in a number of countries around the world, including emerging markets and the United States. Every asset class is reviewed on an ongoing basis by the Sub-Advisers to determine whether it provides the opportunity to enhance performance or to reduce risk. Exposure to different asset classes and strategies will vary over time, in response to changes in the Sub-Advisers' assessment of changing market, economic, and political factors and events that the Sub-Advisers believe may impact the value of the Fund's investments. The Fund may seek to hedge against adverse changes in the values of the currencies in which its investments are denominated, although it will not be required to do so.

The Fund may invest in fixed income securities to an unlimited extent. Fixed income securities in which the Fund may invest may be obligations of governments or government agencies or instrumentalities, supra-national issuers, or corporate issuers. They may pay fixed, variable, or floating interest rates and may include asset-backed securities, mortgage-backed securities, zero-coupon securities, convertible securities, inflation-indexed bonds, structured notes, bank loans, loan participations, loan assignments, municipal securities, and other securities bearing fixed or variable interest rates of any maturity. The Fund may invest in securities rated in any rating category and in unrated securities, and it may invest any portion of its assets in securities rated below investment grade or in unrated securities considered by the Sub-Advisers to be of comparable quality (so-called "junk bonds").

The investment processes used by the Sub-Advisers may result in frequent trading of the Fund's portfolio securities. The Sub-Advisers may sell an investment for the Fund if they believe that the investment no longer offers attractive potential future returns compared to other investment opportunities or that it presents undesirable risks, or in an attempt to limit losses.

The Fund generally intends to invest in high quality stocks with attractive yield characteristics and sustainable dividend payments to help establish a diversified and liquid portfolio. The Fund may invest in equity securities to an unlimited extent, including common stocks, preferred stocks, securities convertible into common and preferred stock, and non-convertible preferred stocks. The Fund may invest in securities of issuers in their initial public offerings ("IPOs"). In addition to the equity and fixed income investments described above, the Fund may invest in hybrid securities and other alternative investments, such as real estate investment trusts ("REITs") and other property trusts, structured products, and master limited partnerships ("MLPs"). The Sub-Advisers will also invest in cash and cash equivalents strategically, potentially building the Fund's cash position when the advisers believe that attractive investments for the Fund are not available or when the advisers believe that a relatively large cash position will help ensure that the Fund will be able to invest in attractive new opportunities as they become available.
Risk [Heading] rr_RiskHeading
PRINCIPAL RISKS.
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. 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 fund, there is no guarantee that the Fund will achieve its investment objective. For more information regarding risks and investment matters, please see "Additional Information Regarding Investment Strategies and Risks" and "More Information About Risks" in the Fund's statutory prospectus.

Market Risk – Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities may decline in value due to the activities and financial prospects of individual companies or to general market and economic movements and trends, including adverse changes to credit markets.

Equity Risk – The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Mid Cap and Small Cap Securities Risk – Investments in small capitalization and mid capitalization companies involve greater risks than investments in larger, more established companies. Many of these companies are young and have limited operating or business history. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks, include the risks of bankruptcy.

Interest Rate Risk – The risk that your investment may go down in value when interest rates rise, because when interest rates rise, the prices of bonds and fixed rate loans fall. A wide variety of factors can cause interest rates to rise, including central bank monetary policies and inflation rates. Generally, the longer the maturity of a bond or fixed rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund's income. These risks are greater during periods of rising inflation. Volatility in interest rates and in fixed income markets may increase the risk that the Fund's investment in fixed income securities will go down in value. Risks associated with rising interest rates are currently heightened because interest rates in the U.S. are at, or near, historic lows.

Credit Risk – Credit risk is the risk that the issuer of a security or other instrument will not be able to make principal and interest payments when due. Changes in an issuer's financial strength, credit rating or the market's perception of an issuer's creditworthiness may also affect the value of the Fund's investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

High Yield Investments Risk – High yield investments rated below investment grade (also referred to as "junk bonds") are considered to be speculative and are subject to heightened credit risk, which may make the Fund more sensitive to adverse developments in the U.S. and abroad. Lower rated debt securities generally involve greater risk of default or price changes due to changes in the issuer's creditworthiness than higher rated debt securities. The market prices of these securities may fluctuate more than higher quality securities and may decline significantly in periods of general economic difficulty. There may be little trading in the secondary market for particular debt securities, which may make them more difficult to value or sell.

Loans and Loan Participations Risk – Loans and loan participations, including floating rate loans, are subject to credit risk, including the risk of nonpayment of principal or interest. Also, substantial increases in interest rates may cause an increase in loan defaults. Although the loans the Fund holds may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment. In addition, in the event an issuer becomes insolvent, a loan could be subject to settlement risks or administrative disruptions that could adversely affect the Fund's investment. It may also be difficult to obtain reliable information about a loan or loan participation.

Many loans are relatively illiquid or are subject to restrictions on resale and may be difficult to value, which will have an adverse impact on the Fund's ability to dispose of particular loans or loan participations when necessary to meet redemption requests or liquidity needs, or to respond to a specific economic event, such as deterioration in the creditworthiness of the borrower. Loans may also be subject to extension risk (the risk that borrowers will repay a loan more slowly in periods of rising interest rates) and prepayment risk (the risk that borrowers will repay a loan more quickly in periods of falling interest rates). The Fund may acquire a participation interest in a loan that is held by another party. When the Fund's loan interest is a participation, the Fund may have less control over the exercise of remedies than the party selling the participation interest, and it normally would not have any direct rights against the borrower.

Loan interests may not be considered "securities," and purchasers, such as the Fund, may not, therefore, be entitled to rely on the anti-fraud protections of the federal securities laws. The Fund may be in possession of material non-public information about a borrower or issuer as a result of its ownership of a loan or security of such borrower or issuer. Because of prohibitions on trading in securities of issuers while in possession of such information, the Fund may be unable to enter into a transaction in a loan or security of such a Borrower or issuer when it would otherwise be advantageous to do so.

Foreign Investments Risk – Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions, may affect the value of the Fund's investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund's foreign investments.

Emerging Markets Risk – The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation, less extensive and less frequent accounting, financial and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

 

Currency Risk – The risk that the value of the Fund's investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer's local currency.

Mortgage- and Asset-Backed Securities Risk – Mortgage- and asset-backed securities represent interests in "pools" of mortgages or other assets, including consumer loans or receivables held in trust. Mortgage-backed securities are subject to credit risk, interest rate risk, "prepayment risk" (the risk that borrowers will repay a loan more quickly in periods of falling interest rates) and "extension risk" (the risk that borrowers will repay a loan more slowly in periods of rising interest rates). If the Fund invests in mortgage-backed or asset-backed securities that are subordinated to other interests in the same mortgage pool, the Fund may only receive payments after the pool's obligations to other investors have been satisfied. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may limit substantially the pool's ability to make payments of principal or interest to the Fund, reducing the values of those securities or in some cases rendering them worthless. The risk of such defaults is generally higher in the case of mortgage pools that include so-called "subprime" mortgages.

Liquidity Risk – The risk that the market for a particular investment or type of investment is or becomes relatively illiquid, making it difficult for the Fund to sell that investment at an advantageous time or price. Illiquidity may be due to events relating to the issuer of the securities, market events, rising interest rates, economic conditions or investor perceptions. Illiquid securities may be difficult to value and their value may be lower than the market price of comparable liquid securities, which would negatively affect the Fund's performance.

Sovereign Debt Risk – Investments in sovereign debt are subject to the risk that the issuer of the non-U.S. sovereign debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay the principal or interest when due. This may result from political or social factors, the general economic environment of a country or economic region, levels of foreign debt or foreign currency exchange rates.

Active Trading Risk – Active trading could increase the Fund's transaction costs and may increase your tax liability as compared to a fund with less active trading policies. These effects may adversely affect Fund performance.

Volatility Risk –Share price, yield and total return may fluctuate more than with funds that use a different investment strategy.

Leverage Risk – Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly. Leverage may also cause the Fund to be more volatile than if it had not been leveraged. The use of leverage may cause the Fund to liquidate portfolio positions to satisfy its obligations or to meet asset segregation requirements when it may not be advantageous to do so.

Investment Strategy Risk – The risk that, if the Sub-Advisers' investment strategy does not perform as expected, the Fund could underperform its peers or lose money. There is no guarantee that the Fund's investment objective will be achieved.

Large Shareholder Transaction Risk – The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund's net asset value ("NAV") and liquidity. Similarly, large Fund share purchases may adversely affect a Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks, which are discussed in "Additional Information Regarding Investment Strategies and Risks" and "More Information About Risks" in the Fund's statutory prospectus.
