Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 19% of the average value of its portfolio.

Under normal circumstances, the Fund invests at least 80% of its assets in RidgeWorth Equity Funds and exchange-traded funds (“ETFs”) that invest in equity securities (together, “Underlying Funds”). The Fund’s remaining assets may be invested in cash and cash equivalents, including unaffiliated money market funds, securities issued by the U.S. government, its agencies or instrumentalities, repurchase agreements, and short-term paper.

The Fund may invest in an Underlying Fund that:

– invests in common stocks of real estate investment trusts (“REITs”) and companies principally engaged in the real estate industry.

– invests in common stocks and other equity securities of U.S. and non U.S. companies. Certain Underlying Funds may invest in companies of any size and in both developed and emerging markets.

In selecting a diversified portfolio of Underlying Funds, the Adviser analyzes many factors, including the Underlying Funds’ investment objectives, total return, volatility and expenses.

The table below shows how the Adviser currently expects to allocate the Fund’s portfolio among asset classes. The table also shows the sectors within those asset classes to which the Fund may have exposure.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The value of an investment in the Fund is based primarily on the performance of the Underlying Funds and the allocation of the Fund’s assets among them. The Adviser’s asset allocation decisions may not anticipate market trends successfully. The risks of the Fund will directly correspond to the risks of the Underlying Funds in which it invests. These risks will vary depending upon how the assets are allocated among the Underlying Funds. Certain risks associated with investing in the Underlying Funds are described in this section.

Asset Allocation Risk: Asset allocation risk is the risk that the Fund could lose money as a result of less than optimal or poor asset allocation decisions as to how its assets are allocated or re-allocated.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

Small- and Mid-Capitalization Companies Risk: Small- and mid-cap stocks tend to perform differently from other segments of the equity market or the equity market as a whole, and can be more volatile than stocks of large-capitalization companies. Small- and mid-capitalization companies may be newer or less established and may have limited resources, products and markets, and be less liquid.

Value Investing Risk: Value investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth. It is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued by the Fund or an Underlying Fund may actually be appropriately priced or remained undervalued.

Growth Stock Risk: Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Growth stocks typically are sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth stocks typically fall.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments. These risks are increased for investments in emerging markets.

Exchange-Traded Fund Risk: The risk of owning shares of an ETF generally reflects the risk of owning the underlying securities the ETF is designed to track. Liquidity in an ETF could result in more volatility than ownership of the underlying portfolio of securities. In addition, because of ETF’s management expenses, compared to owning the underlying securities directly, it may be more costly to own an ETF.

Interest Rate Risk: Debt securities will generally lose value if interest rates increase. U.S. government securities can exhibit price movements resulting from changes in interest rates. Interest rate risk is generally higher for investments with longer maturities or durations.

Real Estate Investment Risk: The Fund or an Underlying ETF invests in companies that invest in real estate and is exposed to risks specific to the real estate market, including interest rate risk, leverage risk, property risk and management risk.

The Fund invests pursuant to an asset allocation strategy in a combination of RidgeWorth Fixed Income Funds and exchange-traded funds (“ETFs”) that invest in bonds (together, “Underlying Fixed Income Funds”), and to a lesser extent, RidgeWorth Equity Funds and ETFs that invest in equities (together, “Underlying Equity Funds”). The Fund invests primarily in Underlying Fixed Income Funds, but may invest up to 40% of its assets in Underlying Equity Funds. The Fund’s remaining assets may be invested in cash and cash equivalents, including unaffiliated money market funds, securities issued by the U.S. government, its agencies or instrumentalities, repurchase agreements and short-term paper.

The Fund may invest in an Underlying Fund that:

– invests in debt instruments, including mortgage- and asset-backed instruments, common stocks and other equity securities of U.S. and non U.S. companies including those in both developed and emerging markets.

– invests in bank loans and other below investment grade instruments.

– invests in inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS,” which are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors.

In selecting a diversified portfolio of Underlying Fixed Income Funds and Underlying Equity Funds (together, “Underlying Funds”), the Adviser analyzes many factors, including the Underlying Funds’ investment objectives, total return, volatility and expenses.

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The value of an investment in the Fund is based primarily on the performance of the Underlying Funds and the allocation of the Fund’s assets among them. The Adviser’s asset allocation decisions may not anticipate market trends successfully. The risks of the Fund will directly correspond to the risks of the Underlying Funds in which it invests. These risks will vary depending upon how the assets are allocated among the Underlying Funds. Certain risks associated with investing in the Underlying Funds are described in this section.

Asset Allocation Risk: Asset allocation risk is the risk that the Fund could lose money as a result of less than optimal or poor asset allocation decisions as to how its assets are allocated or re-allocated.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds,” including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Adviser to be of comparable quality, at the time of purchase, involve greater risk of default or downgrade and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to legal or contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities including difficult or frozen credit markets, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case securities backed by loans made to borrowers with “sub-prime” credit metrics.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called the Fund or an Underlying Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates resulting in unexpected capital loss and/or a decline in the Fund’s income.

Real Estate Investment Risk: The Fund or an underlying ETF invests in companies that invest in real estate and is exposed to risks specific to the real estate market, including interest rate risk, leverage risk, property risk and management risk.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of its Treasury obligations to decline. Treasury inflation protected securities (“TIPS”) can also exhibit price movements as a result of changing inflation expectations and seasonal inflation patterns. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

Small- and Mid-Capitalization Companies Risk: Small- and mid-cap stocks tend to perform differently from other segments of the equity market or the equity market as a whole, and can be more volatile than stocks of large-capitalization companies. Small- and mid-capitalization companies may be newer or less established and may have limited resources, products and markets, and be less liquid.

Value Investing Risk: Value investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth. It is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued by the Fund or an Underlying Fund may actually be appropriately priced or remained undervalued.

Growth Stock Risk: Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Growth stocks typically are sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth stocks typically fall.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments. These risks are increased for investments in emerging markets.

Exchange-Traded Fund Risk: The risk of owning shares of an ETF generally reflects the risk of owning the underlying securities the ETF is designed to track. Liquidity in an ETF could result in more volatility than ownership of the underlying portfolio of securities. In addition, because of ETF’s management expenses, compared to owning the underlying securities directly, it may be more costly to own an ETF.

The Fund invests pursuant to an asset allocation strategy in a combination of RidgeWorth Equity Funds and exchange-traded funds (“ETFs”) that invest in equities (together, “Underlying Equity Funds”), and, to a lesser extent, RidgeWorth Fixed Income Funds and ETFs that invest in bonds (together, “Underlying Fixed Income Funds”). The Fund invests between 60% and 80% of its assets in Underlying Equity Funds and up to 40% in Underlying Fixed Income Funds (together, “Underlying Funds”). The Fund’s remaining assets may be invested in cash and cash equivalents, including unaffiliated money market funds, securities issued by the U.S. government, its agencies or instrumentalities, repurchase agreements and short-term paper.

The Fund may invest in an Underlying Fund that:

– invests in common stocks, other equity securities and debt instruments, including mortgage- and asset-backed instruments, of U.S. and non U.S. companies. The Underlying Fund may invest in companies of any size and in both developed and emerging markets.

– invests in bank loans and other below investment grade instruments.

– invests in inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS,” which are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors.

In selecting a diversified portfolio of Underlying Funds, the Adviser analyzes many factors, including the Underlying Funds’ investment objectives, total returns, volatility and expenses. The table below shows how the Adviser currently expects to allocate the Fund’s portfolio among asset classes. The table also shows the sectors within those asset classes to which the Fund will currently have exposure.

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

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The value of an investment in the Fund is based primarily on the performance of the Underlying Funds and the allocation of the Fund’s assets among them. The Adviser’s asset allocation decisions may not anticipate market trends successfully. The risks of the Fund will directly correspond to the risks of the Underlying Funds in which it invests. These risks will vary depending upon how the assets are allocated among the Underlying Funds. Certain risks associated with investing in the Underlying Funds are described in this section.

Asset Allocation Risk: Asset allocation risk is the risk that the Fund could lose money as a result of less than optimal or poor asset allocation decisions as to how its assets are allocated or re-allocated.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

Value Investing Risk: Value investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth. It is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued by the Fund or an Underlying Fund may actually be appropriately priced or remained undervalued.

Growth Stock Risk: Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Growth stocks typically are sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth stocks typically fall.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments. These risks are increased for investments in emerging markets.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds,” including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Adviser to be of comparable quality, at the time of purchase, involve greater risk of default or downgrade and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to legal or contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities including difficult or frozen credit markets, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case securities backed by loans made to borrowers with “sub-prime” credit metrics.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called the Fund or an Underlying Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates resulting in unexpected capital loss and/or a decline in the Fund’s income.

Real Estate Investment Risk: The Fund or an underlying ETF invests in companies that invest in real estate and is exposed to risks specific to the real estate market, including interest rate risk, leverage risk, property risk and management risk.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of its Treasury obligations to decline. Treasury inflation protected securities (“TIPS”) can also exhibit price movements as a result of changing inflation expectations and seasonal inflation patterns. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Exchange-Traded Fund Risk: The risk of owning shares of an ETF generally reflects the risk of owning the underlying securities the ETF is designed to track. Liquidity in an ETF could result in more volatility than ownership of the underlying portfolio of securities. In addition, because of ETF’s management expenses, compared to owning the underlying securities directly, it may be more costly to own an ETF.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 33% of the average value of its portfolio.

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

The Fund invests pursuant to an asset allocation strategy in a combination of RidgeWorth Equity Funds, RidgeWorth Fixed Income Funds and exchange-traded funds (“ETFs”) (together, “Underlying Funds”). The Fund principally invests between 40% and 60% in Underlying Funds that invest primarily in equity securities and up to 60% in Underlying Funds that invest primarily in fixed income securities. The Fund’s remaining assets may be invested in cash and cash equivalents, including unaffiliated money market funds, securities issued by the U.S. government, its agencies or instrumentalities, repurchase agreements and short-term paper.

The Fund may invest in an Underlying Fund that:

– invests in common stocks, other equity securities and debt instruments, including mortgage- and asset-backed instruments, of U.S. and non U.S. companies. The Underlying Fund may invest in companies of any size and in both developed and emerging markets.

– invests in bank loans and other below investment grade instruments.

– invests in inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS,” which are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors.

In selecting a diversified portfolio of Underlying Funds, the Adviser analyzes many factors, including the Underlying Funds’ investment objectives, total returns, volatility and expenses.

The table below shows how the Adviser currently expects to allocate the Fund’s portfolio among asset classes. The table also shows the sectors within those asset classes to which the Fund will currently have exposure.

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

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The value of an investment in the Fund is based primarily on the performance of the Underlying Funds and the allocation of the Fund’s assets among them. The Adviser’s asset allocation decisions may not anticipate market trends successfully. The risks of the Fund will directly correspond to the risks of the Underlying Funds in which it invests. These risks will vary depending upon how the assets are allocated among the Underlying Funds. Certain risks associated with investing in the Underlying Funds are described in this section.

Asset Allocation Risk: Asset allocation risk is the risk that the Fund could lose money as a result of less than optimal or poor asset allocation decisions as to how its assets are allocated or re-allocated.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

Value Investing Risk: Value investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth. It is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued by the Fund or an Underlying Fund may actually be appropriately priced or remained undervalued.

Growth Stock Risk: Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Growth stocks typically are sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth stocks typically fall.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments. These risks are increased for investments in emerging markets.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds,” including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Adviser to be of comparable quality, at the time of purchase, involve greater risk of default or downgrade and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to legal or contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities including difficult or frozen credit markets, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called the Fund or an Underlying Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates resulting in unexpected capital loss and/or a decline in the Fund’s income.

Real Estate Investment Risk: The Fund or an underlying ETF invests in companies that invest in real estate and is exposed to risks specific to the real estate market, including interest rate risk, leverage risk, property risk and management risk.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of its Treasury obligations to decline. Treasury inflation protected securities (“TIPS”) can also exhibit price movements as a result of changing inflation expectations and seasonal inflation patterns. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Exchange-Traded Fund Risk: The risk of owning shares of an ETF generally reflects the risk of owning the underlying securities the ETF is designed to track. Liquidity in an ETF could result in more volatility than ownership of the underlying portfolio of securities. In addition, because of ETF’s management expenses, compared to owning the underlying securities directly, it may be more costly to own an ETF.

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

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

The Fund invests in a diversified portfolio of U.S. dollar denominated corporate obligations and other fixed income securities that are rated BBB-/Baa3 or better by Standard & Poor’s Ratings Services, Moody’s Investors Service or Fitch Ratings or unrated securities that the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), believes are of comparable quality. Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in corporate bonds. The Fund may also invest in U.S. Treasury and agency obligations. The Fund may invest in U.S. dollar denominated obligations of U.S. and non-U.S. issuers. The Fund may invest a portion of its assets in securities that are restricted as to resale.

The Fund will maintain an overall credit quality of A- or better. Securities downgraded below BBB-/Baa3 after purchase by all agencies that rate the securities can be retained so long as in the aggregate securities that are rated below BBB-/Baa3 do not constitute more than 10% of the Fund’s total net assets.

The Subadviser attempts to identify investment grade corporate bonds offering above average total return. In selecting corporate debt investments for purchase and sale, the Subadviser seeks out companies with good fundamentals and above average return prospects that are currently priced at attractive levels. The primary basis for security selection is the potential income offered by the security relative to the Subadviser’s assessment of the issuer’s ability to generate the cash flow required to meet its obligations. The Subadviser employs a “bottom-up” approach, identifying investment opportunities based on the underlying financial and economic fundamentals of the specific issuer.

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

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds”), including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Subadviser to be of comparable quality, at the time of purchase, involve greater risk of default or downgrade and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Foreign Companies Risk: Dollar denominated securities of foreign issuers involve special risks such as economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments.

U.S. Government Agencies Risk: Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government agencies debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 128% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests in various types of income producing debt securities including mortgage-and asset-backed securities, government and agency obligations, corporate obligations and floating rate loans. The Fund may invest in debt securities of U.S. and non-U.S. issuers, including emerging market debt. The Fund’s investment in non-U.S. issuers may at times be significant. Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in fixed-income securities. These securities will be chosen from the broad universe of available intermediate term fixed-income securities rated investment grade by Standard & Poor’s Ratings Services, Moody’s Investors Service or Fitch Ratings or unrated securities that the Fund’s Subadviser, Seix Investment Advisors LLC, (“Seix” or the “Subadviser”), believes are of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade, high yield debt obligations. The Fund may also invest a portion of its assets in securities that are restricted as to resale.

The Subadviser invests in intermediate term fixed-income securities with an emphasis on corporate and mortgage backed securities. The Subadviser anticipates that the Fund will maintain an average weighted maturity of 3 to 10 years and the Fund will be managed with a duration that is close to that of its comparative benchmark, the Barclays Capital Intermediate U.S. Government/Credit Bond Index, which is generally between 3 to 4 years. In selecting investments for purchase and sale, the Subadviser generally selects a greater weighting in obligations of domestic corporations and mortgage-backed securities relative to the Fund’s comparative benchmark, and a lower relative weighting in U.S. Treasury and government agency issues.

In addition, to implement its investment strategy, the Fund may buy or sell derivative instruments (such as foreign currency forward contracts, swaps, including credit default swaps, futures, credit linked notes, options, inverse floaters and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit risks. The Fund may count the value of certain derivatives with investment grade intermediate-term fixed income characteristics towards its policy to invest, under normal circumstances, at least 80% of its net assets in fixed-income securities.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

If market interest rates increase substantially and the Fund’s adjustable-rate securities are not able to reset to market interest rates during any one adjustment period, the value of the Fund’s holdings and its net asset value may decline until the adjustable-rate securities are able to reset to market rates. In the event of a dramatic increase in interest rates, the lifetime limit on a security’s interest rate may prevent the rate from adjusting to prevailing market rates. In such an event the security could underperform and affect the Fund’s net asset value.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments and delays in enforcement of rights. These risks are increased for investments in emerging markets.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds”), including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Subadviser to be of comparable quality, at the time of purchase, involve greater risk of default or downgrade and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Foreign Currency Forward Contracts Risk: The technique of purchasing foreign currency forward contracts to obtain exposure to currencies or manage currency risk may not be effective. In addition, currency markets generally are not as regulated as securities markets.

Swap Risk: The Fund may enter into swap agreements, including credit default and interest rate swaps, for purposes of attempting to gain exposure to a particular asset without actually purchasing that asset or to hedge a position. Credit default swaps may increase or decrease the Fund’s exposure to credit risk and could result in losses if the Subadviser does not correctly evaluate the creditworthiness of the entity on which the credit default swap is based. Swap agreements may also subject the Fund to the risk that the counterparty to the transaction may not meet its obligations.

Futures Contract Risk: The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Leverage Risk: Certain transactions and the use of derivatives such as foreign currency forward contracts, swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of its Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in fixed income securities rated investment grade by at least one national securities rating agency or unrated securities that the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), believes are of comparable quality. The Subadviser focuses on corporate debt securities, U.S. Treasury obligations, mortgage-backed securities and other asset-backed securities. The Fund may invest in debt obligations of U.S. and non U.S. issuers. The Fund’s investment in non-U.S. issuers may at times be significant. The Fund may invest up to 20% of its net assets in below investment grade, high yield debt obligations, including emerging market debt and floating rate loans. The Fund may also invest a portion of its assets in securities that are restricted as to resale.

The Subadviser attempts to identify relatively inexpensive securities in a selected market index, which is currently the Barclays Capital U.S. Government/Credit Bond Index, a widely recognized, unmanaged index of investment grade government and corporate debt securities. In selecting investments for purchase and sale, the Subadviser tries to minimize risk while attempting to outperform selected market indices. The Subadviser seeks to invest more in portions of the Index that seem relatively inexpensive, and less in those that seem expensive. The Subadviser allocates the Fund’s investments among various market sectors based on the Subadviser’s analysis of historical data, yield information and credit ratings.

In addition, to implement its investment strategy, the Fund may buy or sell derivative instruments (such as foreign currency forward contracts, swaps, including credit default swaps, futures, credit linked notes, options, inverse floaters and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit risks.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds”), including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Subadviser to be of comparable quality, at the time of purchase, involve greater risk of default and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Foreign Currency Forward Contracts Risk: The technique of purchasing foreign currency forward contracts to obtain exposure to currencies or manage currency risk may not be effective. In addition, currency markets generally are not as regulated as securities markets.

Swap Risk: The Fund may enter into swap agreements, including credit default and interest rate swaps, for purposes of attempting to gain exposure to a particular asset without actually purchasing that asset or to hedge a position. Credit default swaps may increase or decrease the Fund’s exposure to credit risk and could result in losses if the Subadviser does not correctly evaluate the creditworthiness of the entity on which the credit default swap is based. Swap agreements may also subject the Fund to the risk that the counterparty to the transaction may not meet its obligations.

Futures Contract Risk: The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Leverage Risk: Certain transactions and the use of derivatives such as foreign currency forward contracts, swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of its Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account.

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

The Fund invests in U.S. dollar-denominated, investment grade fixed income securities, including corporate and bank obligations, government securities, and mortgage-and asset-backed securities of U.S. and non-U.S. issuers, rated A or better by Standard & Poor’s Ratings Services, Moody’s Investors Service or Fitch Ratings or unrated securities that the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), believes are of comparable quality. The Fund’s investment in non-U.S. issuers may at times be significant.

The Fund will maintain an average credit quality of AA or Aa and all securities held in the Fund will have interest rate durations of 180 days or less. For floating rate notes, the interest rate duration will be based on the next interest rate reset date. Duration measures a bond or Fund’s sensitivity to interest rate changes and is expressed as a number of years. The higher the number, the greater the risk. Under normal circumstances, for example, if a portfolio has a duration of 5 years, its value will change by 5% if rates change by 1%. Shorter duration bonds result in lower expected volatility.

The Subadviser attempts to identify U.S. dollar-denominated, investment grade fixed income securities that offer high current income while preserving liquidity and principal. In selecting investments for purchase and sale, the Subadviser emphasizes securities that are within the targeted segment of the U.S. dollar-denominated, fixed income securities markets and will generally focus on investments that have good business prospects, credit strength, stable cash flows and effective management. The Subadviser may retain securities if the rating of the security falls below investment grade and the Subadviser deems retention of the security to be in the best interests of the Fund.

In addition, to implement its investment strategy, the Fund may buy or sell, to a limited extent, derivative instruments (such as credit linked notes, futures, options, inverse floaters, swaps and warrants) to use as a substitute for a purchase or sale of a position in the underlying asset and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk and credit risk.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

If market interest rates increase substantially and the Fund’s adjustable-rate securities are not able to reset to market interest rates during any one adjustment period, the value of the Fund’s holdings and its net asset value may decline until the adjustable-rate securities are able to reset to market rates. In the event of a dramatic increase in interest rates, the lifetime limit on a security’s interest rate may prevent the rate from adjusting to prevailing market rates. In such an event the security could underperform and affect the Fund’s net asset value.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

Floating Rate Notes Risk: Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates.

Foreign Securities Risk: Foreign securities involve special risks such as economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments and delays in enforcement of rights. These risks are increased for investments in emerging markets.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of its Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same and you reinvest all dividends and distributions. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 452% of the average value of its portfolio.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. government agency mortgage-backed securities, such as the Federal National Mortgage Association (“Fannie Mae”), Government National Mortgage Association (“GNMA”) and collateralized mortgage obligations.

In selecting investments for purchase and sale, the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), attempts to identify securities that it expects to perform well in rising and falling markets. The Subadviser also attempts to reduce the risk that the underlying mortgages are prepaid by focusing on securities that it believes are less prone to this risk. For example, Fannie Mae or GNMA securities that were issued years ago may be less prone to prepayment risk because there have been many opportunities for refinancing.

In addition, to implement its investment strategy, the Fund may buy or sell, to a limited extent, derivative instruments (such as credit linked notes, futures, options, inverse floaters, swaps and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk and credit risk.

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

If market interest rates increase substantially and the Fund’s adjustable-rate securities are not able to reset to market interest rates during any one adjustment period, the value of the Fund’s holdings and its net asset value may decline until the adjustable-rate securities are able to reset to market rates. In the event of a dramatic increase in interest rates, the lifetime limit on a security’s interest rate may prevent the rate from adjusting to prevailing market rates. In such an event the security could underperform and affect the Fund’s net asset value.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of its Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Obligations of certain agencies, authorities, instrumentalities and sponsored enterprises of the U.S. government are backed by the full faith and credit of the United States (e.g., Fannie Mae); other obligations are backed by the right of the issuer to borrow from the U.S. Treasury (e.g., the Federal Home Loan Banks); and others are supported by the discretionary authority of the U.S. government to purchase an agency’s obligations. Still others are backed only by the credit of the agency, authority, instrumentality or sponsored enterprise issuing the obligation. No assurance can be given that the U.S. government would provide financial support to any of these entities if it is not obligated to do so by law.

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

The Fund invests in various types of income producing debt securities including mortgage- and asset-backed securities, government and agency obligations, corporate obligations and floating rate loans. The Fund may invest in debt obligations of U.S. and non-U.S. issuers, including emerging market debt. The Fund’s investment in non-U.S. issuers may at times be significant. Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in fixed income securities. These securities will be chosen from the broad universe of available fixed income securities rated investment grade by Standard & Poor’s Ratings Services, Moody’s Investors Service or Fitch Ratings or unrated securities that the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), believes are of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade, high yield debt obligations. The Fund may also invest a portion of its assets in securities that are restricted as to resale.

The Subadviser anticipates that the Fund’s modified adjusted duration will generally range from 3 to 6 years, similar to that of the Barclays Capital U.S. Aggregate Bond Index, the Fund’s comparative benchmark. Duration measures a bond or Fund’s sensitivity to interest rate changes and is expressed as a number of years. The higher the number, the greater the risk. Under normal circumstances, for example, if a portfolio has a duration of five years, its value will change by 5% if rates change by 1%. Shorter duration bonds result in lower expected volatility. In selecting investments for purchase and sale, the Subadviser generally selects a greater weighting in obligations of domestic corporations and mortgage-backed securities relative to the Fund’s comparative benchmark, and a lower relative weighting in U.S. Treasury and government agency issues.

In addition, to implement its investment strategy, the Fund may buy or sell derivative instruments (such as foreign currency forward contracts, swaps, including credit default swaps, futures, credit linked notes, options, inverse floaters and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit risks. The Fund may count the value of certain derivatives with investment grade fixed income characteristics towards its policy to invest, under normal circumstances, at least 80% of its net assets in fixed income securities.

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

If market interest rates increase substantially and the Fund’s adjustable-rate securities are not able to reset to market interest rates during any one adjustment period, the value of the Fund’s holdings and its net asset value may decline until the adjustable-rate securities are able to reset to market rates. In the event of a dramatic increase in interest rates, the lifetime limit on a security’s interest rate may prevent the rate from adjusting to prevailing market rates. In such an event the security could underperform and affect the Fund’s net asset value.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds”), including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Subadviser to be of comparable quality, at the time of purchase, involve greater risk of default and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Foreign Currency Forward Contracts Risk: The technique of purchasing foreign currency forward contracts to obtain exposure to currencies or manage currency risk may not be effective. In addition, currency markets generally are not as regulated as securities markets.

Swap Risk: The Fund may enter into swap agreements, including credit default and interest rate swaps, for purposes of attempting to gain exposure to a particular asset without actually purchasing that asset or to hedge a position. Credit default swaps may increase or decrease the Fund’s exposure to credit risk and could result in losses if the Subadviser does not correctly evaluate the creditworthiness of the entity on which the credit default swap is based. Swap agreements may also subject the Fund to the risk that the counterparty to the transaction may not meet its obligations.

Futures Contract Risk: The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Leverage Risk: Certain transactions and the use of derivatives such as foreign currency forward contracts, swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of its Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock The bar chart and the performance table that follow illustrate the risks and volatility of an investment in the Fund. The Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future. The Fund began operating on October 11, 2004. The performance for I Shares prior to such date is that of the I Shares of the Seix Core Bond Fund, the Fund’s predecessor. The performance for A Shares from January 25, 2002 to October 11, 2004 is that of the P Shares of the Seix Core Bond Fund. The performance for A Shares prior to January 25, 2002 is that of the I Shares of the Seix Core Bond Fund. The performance of the predecessor fund has not been adjusted to reflect the Fund’s A Share or R Share expenses. If it had been, performance would have been lower. The performance shown below prior to the conversion of C Shares to R Shares at the close of business on February 12, 2009, is that of C Shares.

The Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. government debt securities, such as mortgage-backed securities and U.S. Treasury obligations and shares of registered money market mutual funds that invest in the foregoing. In selecting investments for purchase and sale, the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), focuses its investments in mortgage-backed securities in an attempt to provide a consistently high dividend without adding undue risk. Under certain circumstances, the Subadviser may strategically position the Fund’s exposure across the yield curve to potentially benefit from a normalization of the term structure of rates (i.e., in an environment where the yield curve is abnormally steep, investments will be strategically positioned along the yield curve to benefit as the curve’s shape reverts to a more traditional, or normal slope).

In addition, to implement its investment strategy, the Fund may buy or sell, to a limited extent, derivative instruments (such as credit linked notes, futures, options, inverse floaters, swaps and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. government debt securities, such as mortgage-backed securities and U.S. Treasury obligations and shares of registered money market mutual funds that invest in the foregoing.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

If market interest rates increase substantially and the Fund’s adjustable-rate securities are not able to reset to market interest rates during any one adjustment period, the value of the Fund’s holdings and its net asset value may decline until the adjustable-rate securities are able to reset to market rates. In the event of a dramatic increase in interest rates, the lifetime limit on a security’s interest rate may prevent the rate from adjusting to prevailing market rates. In such an event the security could underperform and affect the Fund’s net asset value.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

U.S. Government Debt Securities Risk: U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of U.S. Treasury obligations to decline. Treasury Inflation Protected Securities (“TIPS”) can also exhibit price movements as a result of changing inflation expectations and seasonal inflation patterns. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

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

The Fund invests primarily in a diversified portfolio of higher yielding, lower-rated income producing debt instruments, including corporate obligations, floating rate loans and other debt obligations. The Fund may invest in debt obligations of U.S. and non-U.S. issuers, including emerging market debt. The Fund’s investment in non-U.S. issuers may at times be significant. The Fund will invest at least 65%, and may invest up to 100%, of its assets in securities rated below investment grade by either Moody’s Investors Service or Standard & Poor’s Ratings Services or in unrated securities that the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), believes are of comparable quality. Such securities are commonly known as “junk bonds” and offer greater risks than investment grade debt securities. The Fund may also invest a portion of its assets in securities that are restricted as to resale.

In selecting investments for purchase and sale, the Subadviser employs a research driven process designed to identify value areas within the high yield market. The Subadviser seeks to identify securities which generally seek to meet the following criteria: (i) industries that have sound fundamentals; (ii) companies that have good business prospects and increasing credit strength; and (iii) issuers with stable or growing cash flows and effective management.

In addition, to implement its investment strategy, the Fund may buy or sell derivative instruments (such as swaps, including credit default swaps, futures, credit linked notes, options, inverse floaters and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit risks. The Fund may count the value of certain derivatives with below investment grade fixed income characteristics towards its policy to invest, under normal circumstances, at least 65% of its net assets in non-investment grade fixed income securities.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund will invest at least 65%, and may invest up to 100%, of its assets in securities rated below investment grade by either Moody’s Investors Service or Standard & Poor’s Ratings Services or in unrated securities that the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), believes are of comparable quality.
Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds”), including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Subadviser to be of comparable quality, at the time of purchase, involve greater risk of default and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments and delays in enforcement of rights. These risks are increased for investments in emerging markets.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Futures Contract Risk: The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Swap Risk: The Fund may enter into swap agreements, including credit default and interest rate swaps, for purposes of attempting to gain exposure to a particular asset without actually purchasing that asset or to hedge a position. Credit default swaps may increase or decrease the Fund’s exposure to credit risk and could result in losses if the Subadviser does not correctly evaluate the creditworthiness of the entity on which the credit default swap is based. Swap agreements may also subject the Fund to the risk that the counterparty to the transaction may not meet its obligations.

Foreign Currency Forward Contracts Risk: The technique of purchasing foreign currency forward contracts to obtain exposure to currencies or manage currency risk may not be effective. In addition, currency markets generally are not as regulated as securities markets.

Leverage Risk: Certain transactions and the use of derivatives such as foreign currency forward contracts, swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of U.S. Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a combination of first and second lien senior floating rate loans and other floating rate debt securities.

These loans are loans made by banks and other large financial institutions to various companies and are senior in the borrowing companies’ capital structure. Coupon rates are floating, not fixed, and are tied to a benchmark lending rate, the most popular of which is the London Interbank Offered Rate (“LIBOR”). LIBOR is based on rates that contributor banks in London charge each other for interbank deposits and is typically used to set coupon rates on floating rate debt securities.

The interest rates of these floating rate debt securities vary periodically based upon a benchmark indicator of prevailing interest rates. The Fund may invest all or substantially all of its assets in floating rate loans and debt securities that are rated below investment grade by Moody’s Investors Service or Standard & Poor’s Ratings Services or in comparable unrated securities. The Fund may also invest up to 20% of its net assets in any combination of junior debt securities or securities with a lien on collateral lower than a senior claim on collateral, high yield fixed rate bonds, investment grade fixed income debt obligations, asset-backed securities (such as special purpose trusts investing in bank loans), money market securities and repurchase agreements.

In selecting investments for purchase and sale, the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), will emphasize securities which are within the segment of the high yield market it has targeted, which are securities rated either “BB” and “B” by Standard & Poor’s Ratings Services or “Ba” and “B” by Moody’s Investors Service or unrated securities that the Subadviser believes are of comparable quality.

The Fund may invest up to 20% of its total assets in senior loans made to non-U.S. borrowers provided that no more than 5% of the portfolio’s loans are non-U.S. dollar denominated. The Fund may also engage in certain hedging transactions.

Preservation of capital is considered when consistent with the fund’s objective.

Some types of senior loans in which the Fund may invest require that an open loan for a specific amount be continually offered to a borrower. These types of senior loans are commonly referred to as revolvers. Because revolvers contractually obligate the lender (and therefore those with an interest in the loan) to fund the revolving portion of the loan at the borrower’s discretion, the Fund must have funds sufficient to cover its contractual obligation. Therefore the Fund will maintain, on a daily basis, high-quality, liquid assets in an amount at least equal in value to its contractual obligation to fulfill the revolving senior loan. The Fund will not encumber any assets that are otherwise encumbered. The Fund will limit its investments in such obligations to no more than 25% of the Fund’s total assets.

In addition, to implement its investment strategy, the Fund may buy or sell derivative instruments (such as swaps, including credit default swaps, futures, credit linked notes, options, inverse floaters and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit risks. The Fund may count the value of certain derivatives with floating rate debt or high yield bond characteristics towards its policy to invest, under normal circumstances, at least 80% of its net assets in a combination of first and second lien senior floating rate loans and other floating rate debt securities.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss.

Senior Loan Risk: Economic and other market events may reduce the demand for certain senior loans held by the Fund, which may adversely impact the net asset value of the Fund.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds”), including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Subadviser to be of comparable quality, at the time of purchase, involve greater risk of default and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments and delays in enforcement of rights. These risks are increased for investments in emerging markets.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Futures Contract Risk: The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Foreign Currency Forward Contracts Risk: The technique of purchasing foreign currency forward contracts to obtain exposure to currencies or manage currency risk may not be effective. In addition, currency markets generally are not as regulated as securities markets.

Swap Risk: The Fund may enter into swap agreements, including credit default and interest rate swaps, for purposes of attempting to gain exposure to a particular asset without actually purchasing that asset or to hedge a position. Credit default swaps may increase or decrease the Fund’s exposure to credit risk and could result in losses if the Subadviser does not correctly evaluate the creditworthiness of the entity on which the credit default swap is based. Swap agreements may also subject the Fund to the risk that the counterparty to the transaction may not meet its obligations.

Leverage Risk: Certain transactions and the use of derivatives such as foreign currency forward contracts, swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of U.S. Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests in various types of lower rated, higher yielding debt instruments, including corporate obligations, floating rate loans and other debt obligations. The Fund may invest in debt obligations of U.S. and non-U.S. issuers, including emerging market debt. The Fund’s investment in non-U.S. issuers may at times be significant. Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in high yield securities. These securities will be chosen from the broad universe of available U.S. dollar denominated, high yield securities rated below investment grade by either Moody’s Investors Service or Standard & Poor’s Ratings Services or unrated securities that the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), believes are of comparable quality. Such securities are commonly known as “junk bonds” and offer greater risks than investment grade bonds. Although the Fund seeks to achieve its investment objective primarily through investment in high yield securities, the Fund may invest up to 20% of its net assets in investment grade securities. The Fund will be managed with a duration that is close to the Fund’s comparative benchmark, the Merrill Lynch U.S. High Yield BB/B Rated Constrained Index, which is generally between 3 and 6 years. Duration measures a bond or Fund’s sensitivity to interest rate changes and is expressed as a number of years. The higher the number, the greater the risk. Under normal circumstances, for example, if a portfolio has a duration of five years, its value will change by 5% if rates change by 1%. Shorter duration bonds result in lower expected volatility. The Fund may also invest a portion of its assets in securities that are restricted as to resale.

In selecting investments for purchase and sale, the Subadviser employs a research driven process designed to identify value areas within the high yield market and attempts to identify lower rated, higher yielding bonds offering above average total return. Additionally, the Subadviser will emphasize securities which are within the segment of the high yield market it has targeted for emphasis, which are “BB” and “B” rated issuers. The Subadviser seeks to identify securities which generally seek to meet the following criteria: (1) industries that have sound fundamentals; (2) companies that have good business prospects and increasing credit strength; and (3) issuers with stable or growing cash flows and effective management.

In addition, to implement its investment strategy, the Fund may buy or sell derivative instruments (such as swaps, including credit default swaps, futures, credit linked notes, options, inverse floaters and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit risks. The Fund may count the value of certain derivatives with below investment grade fixed income characteristics towards its policy to invest, under normal circumstances, at least 80% of its net assets in high yield securities.

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds”), including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Subadviser to be of comparable quality, at the time of purchase, involve greater risk of default and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments and delays in enforcement of rights. These risks are increased for investments in emerging markets.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Leverage Risk: Certain transactions and the use of derivatives such as foreign currency forward contracts, swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 44% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in municipal securities with income exempt from U.S. federal and Georgia state income taxes. Issuers of these securities can be located in Georgia, Puerto Rico and other U.S. territories and possessions. The Fund may invest up to 20% of its assets in securities subject to the U.S. federal alternative minimum tax. The Fund may also invest a portion of its net assets in certain taxable debt securities.

In selecting investments for purchase and sale, the Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), tries to manage risk as much as possible. Based on the Subadviser’s analysis of municipalities, credit risk, market trends and investment cycles, the Subadviser attempts to invest more of the Fund’s assets in undervalued market sectors and less in overvalued sectors. There are no limits on the Fund’s average weighted maturity or on the remaining maturities of individual securities. The Subadviser tries to diversify the Fund’s holdings within the State of Georgia. The Subadviser also tries to identify and invest in municipal issuers with improving credit and avoid those with deteriorating credit. The Subadviser may retain securities if the rating of the security falls below investment grade and the Subadviser deems retention of the security to be in the best interests of the Fund.

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

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Concentration Risk: The Fund’s concentration of investments in securities of issuers located in the State of Georgia may subject the Fund to economic and government policies within the State.

Municipal Securities Risk: Municipal securities can be significantly affected by litigation, political or economic events, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders. Municipal securities backed by current or anticipated revenues from specific projects or assets can be negatively affected by the inability of the issuer to collect revenues for the projects or from the assets.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in investment grade municipal securities, including securities subject to the U.S. federal alternative minimum tax, with income exempt from regular U.S. federal income tax. The Fund may invest up to 20% of its assets in securities rated below investment grade by either Moody’s Investors Service or Standard & Poor’s Ratings Services, or unrated securities that the Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), believes are of comparable quality. The Fund may also invest a portion of its net assets in certain taxable debt securities.

In selecting investments for purchase and sale, the Subadviser tries to manage risk as much as possible. Based on the Subadviser’s analysis of municipalities, credit risk, market trends and investment cycles, the Subadviser attempts to invest more of the Fund’s assets in undervalued market sectors and less in overvalued sectors. The Subadviser anticipates that the Fund’s average weighted maturity will range from 5 to 25 years. The Subadviser may retain securities if the rating of the security falls below investment grade and the Subadviser deems retention of the security to be in the best interests of the Fund.

Under normal circumstances, the Fund will invest primarily in municipal securities insured or protected as to timely payment of principal and interest. The Subadviser considers insured or protected bonds to be those bonds covered by a municipal bond insurance company, a recognized state credit enhancement program, or in a pre-refunded position. These situations reduce (but do not eliminate) credit risk.

The Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in investment grade tax-exempt obligations, such as municipal securities. The issuers of these securities may be located in any U.S. state, territory or possession. The Fund may invest up to 20% of its assets in securities subject to the U.S. federal alternative minimum tax. The Fund may also invest a portion of its net assets in certain taxable debt securities.

In selecting investments for purchase and sale, the Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), tries to manage risk as much as possible. Based on the Subadviser’s analysis of municipalities, credit risk, market trends and investment cycles, the Subadviser attempts to invest more of the Fund’s assets in undervalued market sectors and less in overvalued sectors. The Subadviser also tries to identify and invest in municipal issuers with improving credit and avoid those with deteriorating credit. The Subadviser anticipates that the Fund’s average weighted maturity will range from 4 to 10 years. The Fund invests in securities rated investment grade by at least one national securities rating agency or unrated securities that the Subadviser believes are of comparable quality. The Subadviser may retain securities if the rating of the security falls below investment grade and the Subadviser deems retention of the security to be in the best interests of the Fund.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Municipal Securities Risk: Municipal securities can be significantly affected by litigation, political or economic events, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders. Municipal securities backed by current or anticipated revenues from specific projects or assets can be negatively affected by the inability of the issuer to collect revenues for the projects or from the assets.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Concentration Risk: The Fund’s concentration of investments in securities of issuers located in State of Maryland may subject the Fund to economic and government policies within the State.

Municipal Securities Risk: Municipal securities can be significantly affected by litigation, political or economic events, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders. Municipal securities backed by current or anticipated revenues from specific projects or assets can be negatively affected by the inability of the issuer to collect revenues for the projects or from the assets.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in municipal securities with income exempt from U.S. federal and North Carolina state income taxes. Issuers of these securities can be located in North Carolina, Puerto Rico and other U.S. territories and possessions. The Fund may invest up to 20% of its assets in securities subject to the U.S. federal alternative minimum tax. The Fund may also invest a portion of its net assets in certain taxable debt securities.

In selecting investments for purchase and sale, the Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), tries to manage risk as much as possible. Based on the Subadviser’s analysis of municipalities, credit risk, market trends and investment cycles, the Subadviser attempts to invest more of the Fund’s assets in undervalued market sectors and less in overvalued sectors. There are no limits on the Fund’s average weighted maturity or on the remaining maturities of individual securities. The Subadviser tries to diversify the Fund’s holdings within the State of North Carolina. The Subadviser also tries to identify and invest in municipal issuers with improving credit and avoid those with deteriorating credit. The Subadviser may retain securities if the rating of the security falls below investment grade and the Subadviser deems retention of the security to be in the best interests of the Fund.

Municipal securities backed by current or anticipated revenues from specific projects or assets can be negatively affected by the inability of the issuer to collect revenues for the projects or from the assets.

Non-Diversification Risk: The Fund is non-diversified, which means that it may invest in the securities of relatively few issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, and may experience increased volatility due to its investments in those securities.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in municipal securities, including securities subject to the U.S. federal alternative minimum tax, with income exempt from regular U.S. federal income tax and Virginia state income tax. Issuers of these securities can be located in Virginia, Puerto Rico and other U.S. territories and possessions. In addition, the Fund may invest a portion of its net assets in certain taxable debt securities.

In selecting investments for purchase and sale, the Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), tries to manage risk by buying investment grade securities. Based on the Subadviser’s analysis of municipalities, credit risk, market trends and investment cycles, the Subadviser attempts to invest more of the Funds assets in undervalued sectors and less in overvalued sectors. The Subadviser expects that the Fund’s average weighted maturity will range from 5 to 10 years but there is no limit on the maturities of individual securities. The Subadviser may retain securities if the rating of the security falls below investment grade and the Subadviser deems retention of the security to be in the best interests of the Fund.

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Concentration Risk: The Fund’s concentration of investments in securities of issuers located in the State of Virginia may subject the Fund to economic and government policies of the State.

Municipal Securities Risk: Municipal securities can be significantly affected by litigation, political or economic events, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders. Municipal securities backed by current or anticipated revenues from specific projects or assets can be negatively affected by the inability of the issuer to collect revenues for the projects or from the assets.

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.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a diversified portfolio of short- to medium-term investment grade U.S. Treasury, corporate debt, mortgage-backed and asset-backed securities. These securities may be rated investment grade by at least one national securities rating agency or may be unrated securities that the Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), believes are of comparable quality. The Fund expects that it will normally maintain an effective maturity of 3 years or less. The Fund may invest in foreign securities, which at times may be significant.

In selecting securities for purchase and sale, the Subadviser attempts to identify securities that are expected to offer a comparably better investment return for a given level of risk. For example, short-term bonds generally have better returns than money market instruments with a fairly modest increase in risk and/or volatility. The Subadviser manages the Fund from a total return perspective. That is, the Subadviser makes day-to-day investment decisions for the Fund with a view towards maximizing returns. The Subadviser analyzes, among other things, yields, market sectors and credit risk in an effort to identify attractive investments with attractive risk/reward trade-offs.

The Subadviser may retain securities if the rating of the security falls below investment grade and the Subadviser deems retention of the security to be in the best interests of the Fund.

In addition, to implement its investment strategy, the Fund may buy or sell derivative instruments (such as swaps, including credit default swaps, futures and options) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk.

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

If market interest rates increase substantially and the Fund’s adjustable-rate securities are not able to reset to market interest rates during any one adjustment period, the value of the Fund’s holdings and its net asset value may decline until the adjustable-rate securities are able to reset to market rates. In the event of a dramatic increase in interest rates, the lifetime limit on a security’s interest rate may prevent the rate from adjusting to prevailing market rates. In such an event the security could underperform and affect the Fund’s net asset value.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments and delays in enforcement of rights.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Futures Contract Risk: The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Swap Risk: The Fund may enter into swap agreements, including credit default and interest rate swaps, for purposes of attempting to gain exposure to a particular asset without actually purchasing that asset or to hedge a position. Credit default swaps may increase or decrease the Fund’s exposure to credit risk and could result in losses if the Subadviser does not correctly evaluate the creditworthiness of the entity on which the credit default swap is based. Swap agreements may also subject the Fund to the risk that the counterparty to the transaction may not meet its obligations.

Leverage Risk: Certain transactions and the use of derivatives such as swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds”), including those bonds rated lower than “BBB-” by Standard and Poor’s and Fitch, Inc. or “Baa3” by Moody’s Investors Services, Inc.), or that are unrated but judged by the Subadviser to be of comparable quality, at the time of purchase, involve greater risk of default and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of U.S. Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

The Fund invests exclusively in short-term U.S. Treasury securities (those with remaining maturities of 5 years or less) and shares of registered money market funds that invest in the foregoing. The Fund intends to maintain an average weighted maturity from 1 to 3 years.

The Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), manages the Fund from a total return perspective. That is, the Subadviser makes day to day investment decisions for the Fund with a view toward maximizing total return. In selecting investments for purchase and sale, the Subadviser attempts to identify U.S. Treasury securities with maturities that offer a comparably better return potential and yield than either shorter maturity or longer maturity securities for a given level of interest rate risk.

In addition, to implement its investment strategy, the Fund may buy or sell, to a limited extent, derivative instruments (such as futures, options and swaps) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk.

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

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Short-term U.S. Treasury Securities Risk: Short-term U.S. Treasury securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Futures Contract Risk: The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Swap Risk: The Fund may enter into swap agreements, including credit default and interest rate swaps, for purposes of attempting to gain exposure to a particular asset without actually purchasing that asset or to hedge a position. Credit default swaps may increase or decrease the Fund’s exposure to credit risk and could result in losses if the Subadviser does not correctly evaluate the creditworthiness of the entity on which the credit default swap is based. Swap agreements may also subject the Fund to the risk that the counterparty to the transaction may not meet its obligations.

Leverage Risk: Certain transactions and the use of derivatives such as swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of its Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in short duration, investment grade money market and fixed income securities including, but not limited to, U.S. Treasury and agency securities, obligations of supranational entities and foreign governments, domestic and foreign corporate debt obligations, taxable municipal debt securities, mortgage-backed and asset-backed securities, repurchase agreements, and other mutual funds. The Fund’s investment in foreign issuers may at times be significant. The Fund normally expects to maintain an average effective duration between 3 months and 1 year. Individual purchases will generally be limited to securities with an effective duration of less than 5 years. Duration measures a bond or Fund’s sensitivity to interest rate changes and is expressed as a number of years. The higher the number, the greater the risk. Under normal circumstances, for example, if a portfolio has a duration of five years, its value will change by 5% if rates change by 1%. Shorter duration bonds result in lower expected volatility.

In selecting investments for purchase and sale, the Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), attempts to maximize income by identifying securities that offer an acceptable yield for a given level of credit risk and maturity. The Subadviser attempts to identify short duration securities that offer a comparably better return potential and yield than money market funds. The Subadviser may retain securities if the rating of the security falls below investment grade and the Subadviser deems retention of the security to be in the best interests of the Fund.

In addition, to implement its investment strategy, the Fund may buy or sell, derivative instruments (such as swaps, including credit default swaps, futures and options) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk.

In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

If market interest rates increase substantially and the Fund’s adjustable-rate securities are not able to reset to market interest rates during any one adjustment period, the value of the Fund’s holdings and its net asset value may decline until the adjustable-rate securities are able to reset to market rates. In the event of a dramatic increase in interest rates, the lifetime limit on a security’s interest rate may prevent the rate from adjusting to prevailing market rates. In such an event the security could underperform and affect the Fund’s net asset value.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments and delays in enforcement of rights.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Futures Contract Risk: The Fund may enter into futures contracts. The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Swap Risk: The Fund may enter into swap agreements, including credit default and interest rate swaps, for purposes of attempting to gain exposure to a particular asset without actually purchasing that asset or to hedge a position. Credit default swaps may increase or decrease the Fund’s exposure to credit risk and could result in losses if the Subadviser does not correctly evaluate the creditworthiness of the entity on which the credit default swap is based. Swap agreements may also subject the Fund to the risk that the counterparty to the transaction may not meet its obligations.

Leverage Risk: Certain transactions and the use of derivatives such as swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of U.S. Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in short duration U.S. Treasury securities, U.S. agency securities, U.S. agency mortgage-backed securities, repurchase agreements, other U.S. government securities and shares of registered money market mutual funds that invest in the foregoing. The Fund expects to maintain an average effective duration between 3 months and 1 year. Individual purchases will generally be limited to securities with an effective duration of less than 5 years. Duration measures a bond or Fund’s sensitivity to interest rate changes and is expressed as a number of years. The higher the number, the greater the risk. Under normal circumstances, for example, if a portfolio has a duration of five years, its value will change by 5% if rates change by 1%. Shorter duration bonds result in lower expected volatility.

In selecting securities for purchase and sale, the Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), attempts to maximize income by identifying securities that offer an acceptable yield for a given maturity.

In addition, to implement its investment strategy, the Fund may buy or sell, to a limited extent, derivative instruments (such as futures, options and swaps) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in short duration U.S. Treasury securities, U.S. agency securities, U.S. agency mortgage-backed securities, repurchase agreements, other U.S. government securities and shares of registered money market mutual funds that invest in the foregoing.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s 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 the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

If market interest rates increase substantially and the Fund’s adjustable-rate securities are not able to reset to market interest rates during any one adjustment period, the value of the Fund’s holdings and its net asset value may decline until the adjustable-rate securities are able to reset to market rates. In the event of a dramatic increase in interest rates, the lifetime limit on a security’s interest rate may prevent the rate from adjusting to prevailing market rates. In such an event the security could underperform and affect the Fund’s net asset value.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S.-traded equity securities of large-capitalization companies. U.S.-traded equity securities may include American Depositary Receipts (“ADRs”). Ceredex Value Advisors LLC (“Ceredex” or the “Subadviser”) considers large-capitalization companies to be companies with market capitalizations similar to those of companies in the Russell 1000® Value Index. As of July 1, 2011, the market capitalization range of companies in the Russell 1000® Value Index was between approximately $519.1 million and $400.9 billion.

In selecting investments for purchase and sale, the Subadviser chooses companies that it believes are undervalued in the market relative to the industry sector and the company’s own valuation history. The Subadviser evaluates potential catalysts that may cause an upward re-rating of the stock’s valuation. Additionally, the common stocks purchased for the Fund generally pay dividends at the time of purchase or are expected to pay dividends soon after their purchase.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S.-traded equity securities of large-capitalization companies.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

Value Investing Risk: “Value” investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth. It is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued may actually be appropriately priced.

ADR Risk: The Fund may invest in ADRs, which are depositary receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign company. Investments in ADRs involve risks similar to those accompanying direct investments in foreign securities. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S.-traded equity securities of mid-capitalization companies. U.S.-traded equity securities may include American Depositary Receipts (“ADRs”). Ceredex Value Advisors LLC (“Ceredex” or the “Subadviser”) considers mid-capitalization companies to be companies with market capitalizations similar to those of companies in the Russell Midcap® Value Index. As of July 1, 2011, the market capitalization range of companies in the Russell Midcap® Value Index was between approximately $519.1 million and $17.8 billion.

In selecting investments for purchase and sale, the Subadviser chooses companies that it believes are undervalued in the market relative to the industry sector and the company’s own valuation history. The Subadviser evaluates potential catalysts that may cause an upward re-rating of the stock’s valuation. Additionally, the common stocks purchased for the Fund generally pay dividends at the time of purchase or are expected to pay dividends soon after their purchase.

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Mid-Capitalization Companies Risk: Mid-cap stocks tend to perform differently from other segments of the equity market or the equity market as a whole, and can be more volatile than stocks of large-capitalization companies. Mid-capitalization companies may be newer or less established and may have limited resources, products and markets, and less liquid.

Value Investing Risk: “Value” investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth. It is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued may actually be appropriately priced.

ADR Risk: The Fund may invest in ADRs, which are depositary receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign company. Investments in ADRs involve risks similar to those accompanying direct investments in foreign securities. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S.-traded equity securities of small-capitalization companies. U.S.-traded equity securities may include American Depositary Receipts (“ADRs”). Ceredex Value Advisors LLC (“Ceredex” or the “Subadviser”) considers small-capitalization companies to be companies with market capitalizations between $50 million and $3 billion or with market capitalizations similar to those of companies in the Russell 2000® Value Index. As of July 1, 2011, the market capitalization range of companies in the Russell 2000® Value Index was between approximately $31.3 million and $3.1 billion.

In selecting investments for purchase and sale, the Subadviser chooses companies that it believes are undervalued in the market relative to the industry sector and the company’s own valuation history. The Subadviser evaluates potential catalysts that may cause an upward re-rating of the stock’s valuation. Additionally, the common stocks purchased for the Fund generally pay dividends at the time of purchase or are expected to pay dividends soon after their purchase.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Small-Capitalization Companies Risk: Small-cap stocks tend to perform differently from other segments of the equity market or the equity market as a whole, and can be more volatile than stocks of mid- or large-capitalization companies. Small-capitalization companies may be newer or less established and may have limited resources, products and markets, and less liquid.

Value Investing Risk: “Value” investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth. It is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued may actually be appropriately priced.

ADR Risk: The Fund may invest in ADRs, which are depositary receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign company. Investments in ADRs involve risks similar to those accompanying direct investments in foreign securities. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers.

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

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks and other U.S.-traded equity securities of large-capitalization companies. U.S.-traded equity securities may include American Depositary Receipts (“ADRs”). Silvant Capital Management LLC (“Silvant” or the “Subadviser”) considers large-capitalization companies to be companies with market capitalizations similar to those of companies in the S&P 500 Index. As of July 1, 2011, the market capitalization range of companies in the S&P 500 Index was between approximately $1.4 billion and $400.9 billion.

The Subadviser applies proprietary quantitative models to rank stocks based on improving fundamentals, valuation, capital deployment and efficiency and sentiment or behavior factors. The Subadviser then uses fundamental research to select the portfolio of stocks it believes has the best current risk/return characteristics. In selecting investments for purchase, the Subadviser seeks companies with strong current earnings, growth in revenue, improving profitability, strong balance sheets, strong current and projected business fundamentals, and reasonable valuation. The Subadviser’s approach attempts to identify a well-defined “investment thesis” (why it believes the company’s current expectations will be increased over the next 3 to 18 months) based on competitive positioning, business model, and potential catalysts and risks. The Subadviser may sell a security when the investment thesis is realized, the investment thesis breaks down, or a more attractive alternative presents itself. The Subadviser believes in executing a very disciplined and objective investment process and controlling risk through a broadly diversified portfolio.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Growth Stock Risk: “Growth” stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. “Growth” stocks typically are sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth stocks typically fall.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

ADR Risk: The Fund may invest in ADRs, which are depositary receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign company. Investments in ADRs involve risks similar to those accompanying direct investments in foreign securities. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 30% of the average value of its portfolio.

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

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks and other U.S.-traded equity securities of large-capitalization companies. U.S.-traded equity securities may include American Depositary Receipts (“ADRs”). Silvant Capital Management LLC (“Silvant” or the “Subadviser”) considers large-capitalization companies to be companies with market capitalizations similar to those of companies in the Russell 1000® Growth Index. As of July 1, 2011, the market capitalization range of companies in the Russell 1000® Growth Index was between approximately $706.3 million and $400.9 billion. The Subadviser will seek out securities it believes have strong business fundamentals, such as revenue growth, improving cash flows, increasing margins and positive earning trends.

In selecting investments for purchase and sale, the Subadviser chooses companies that it believes have above average growth potential to beat expectations. The Subadviser applies proprietary quantitative models to rank stocks based on improving fundamentals, valuation, capital deployment and efficiency and sentiment or behavior factors. It then performs in-depth fundamental analysis to determine the quality and sustainability of expectations to determine whether or not the company is poised to beat expectations. The Subadviser uses a “bottom-up” process based on company fundamentals. Risk controls are in place to assist in maintaining a portfolio that is diversified by sector and minimizes unintended risks relative to the primary benchmark.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Growth Stock Risk: “Growth” stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. “Growth” stocks typically are sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth stocks typically fall.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

ADR Risk: The Fund may invest in ADRs, which are depositary receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign company. Investments in ADRs involve risks similar to those accompanying direct investments in foreign securities. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 72% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks and other U.S.-traded equity securities of large-capitalization companies. U.S.-traded equity securities may include American Depositary Receipts (“ADRs”). Silvant Capital Management LLC (“Silvant” or the “Subadviser”) considers large-capitalization companies to be companies with market capitalizations similar to those of companies in the Russell 1000® Growth Index. As of July 1, 2011, the market capitalization range of companies in the Russell 1000® Growth Index was between approximately $706.3 million and $400.9 billion.

The Subadviser applies proprietary quantitative models to rank stocks based on improving fundamentals, valuation, capital deployment and efficiency and sentiment or behavior factors. The Subadviser then uses fundamental research to select the portfolio of stocks it believes has the best current risk/return characteristics. In selecting investments for purchase and sale, the Subadviser seeks companies with strong current earnings, growth in revenue, improving profitability, strong balance sheet, strong current and projected business fundamentals, and reasonable valuation. The Subadviser believes in executing a very disciplined and objective investment process in controlling risk through a broadly diversified portfolio. Generally, the Fund will hold 40 securities or less.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Growth Stock Risk: “Growth” stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. “Growth” stocks typically are sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth stocks typically fall.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

ADR Risk: The Fund may invest in ADRs, which are depositary receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign company. Investments in ADRs involve risks similar to those accompanying direct investments in foreign securities. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers.

Holdings Risk: Because the Fund targets holdings of a more limited number of stocks, performance may be more volatile than a similar fund with a greater number of holdings or the Fund’s respective benchmark.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S.-traded equity securities of small-capitalization companies. U.S.-traded equity securities may include American Depositary Receipts (“ADRs”). Silvant Capital Management LLC (“Silvant” or the “Subadviser”) considers small-capitalization companies to be companies with market capitalizations similar to those of companies in the Russell 2000® Growth Index. As of July 1, 2011, the market capitalization range of companies in the Russell 2000® Growth Index was between approximately $31.3 million and $3.1 billion.

In selecting investments for purchase and sale, the Subadviser chooses companies that it believes have above average growth potential to beat expectations as a result of strong business fundamentals, such as revenue growth, improving cash flows, increasing margins and positive earning trends. The Subadviser applies proprietary quantitative models to rank stocks based on improving fundamentals, valuation, capital deployment and efficiency and sentiment or behavior factors. It then performs in-depth fundamental analysis to determine the quality and sustainability of expectations to determine whether or not the company is poised to beat expectations. The Subadviser uses a “bottom-up” process based on company fundamentals. Risk controls are in place to assist in maintaining a portfolio that is diversified by sector and minimizes unintended risks relative to the primary benchmark.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Growth Stock Risk: “Growth” stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. “Growth” stocks typically are sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth stocks typically fall.

Small-Capitalization Companies Risk: Small-cap stocks tend to perform differently from other segments of the equity market or the equity market as a whole, and can be more volatile than stocks of mid- or large-capitalization companies. Small-capitalization companies may be newer or less established and may have limited resources, products and markets, and less liquid.

ADR Risk: The Fund may invest in ADRs, which are depositary receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign company. Investments in ADRs involve risks similar to those accompanying direct investments in foreign securities. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks and other U.S.-traded equity securities. U.S.-traded equity securities may include American Depositary Receipts (“ADRs”). The Fund may invest in companies of any size and may invest a portion of its assets in non-U.S. issued securities.

The Fund invests primarily in common stocks of companies that exhibit strong growth characteristics. In selecting investments for purchase and sale, Zevenbergen Capital Investments LLC (“Zevenbergen” or the “Subadviser”) uses a fundamental research approach to identify companies with favorable prospects for future revenue, earnings, and/or cash flow growth. Growth “drivers” are identified for each company and become critical to the ongoing evaluation process. Industry growth dynamics, company competitive positioning, pricing flexibility, and diversified product offerings are evaluated, providing the foundation for further fundamental research to determine the weighting of the Fund’s investments. Generally the Fund will hold a limited number of securities.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Holdings Risk: Because the Fund targets holdings of a more limited number of stocks, performance may be more volatile than a similar fund with a greater number of holdings or the Fund’s respective benchmark.

Growth Stock Risk: “Growth” stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. “Growth” stocks typically are sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth stocks typically fall.

Small- and Mid-Capitalization Companies Risk: Small- and mid-cap stocks tend to perform differently from other segments of the equity market or the equity market as a whole, and can be more volatile than stocks of large-capitalization companies. Small- and mid-capitalization companies may be newer or less established and may have limited resources, products and markets, and less liquid.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments. These risks are increased for investments in emerging markets. The Fund is also subject to the risk that foreign equity securities may underperform other segments of the equity market or the equity market as a whole.

U.S.-traded equity securities may include American Depositary Receipts (“ADRs”). The Fund invests primarily in stocks of small and mid-cap growth companies. Zevenbergen Capital Investments LLC (“Zevenbergen” or the “Subadviser”) considers small and mid-cap growth companies to be primarily companies with market capitalizations from $300 million up to the highest capitalization of those companies included in the Russell Midcap® Growth Index (and as annually reconstituted). As of June 24, 2011, the highest capitalization of a company in the Russell Midcap® Growth Index was approximately $17.2 billion. The Subadviser emphasizes initial investment in companies with market capitalizations of $5 billion or less. The Fund may also invest a portion of its assets in non-U.S. issued securities.

In selecting investments for purchase and sale, the Subadviser looks for companies that exhibit strong growth characteristics. Using a fundamental research approach, the Subadviser identifies companies with favorable prospects for future revenue, earnings, and/or cash flow growth. Growth “drivers” are identified for each company and become critical to the ongoing evaluation process. Industry growth dynamics, company competitive positioning, pricing flexibility, and diversified product offerings are evaluated, providing the foundation for further fundamental research to determine the weighting of the Fund’s investments.

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.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 80% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks and other equity securities of foreign companies. The Fund’s investments are diversified among at least three foreign countries. The Fund may also invest in exchange-traded funds (“ETFs”). The Fund invests primarily in developed countries, but may invest in countries with emerging markets.

In selecting investments for purchase and sale, Certium Asset Management LLC (“Certium” or the “Subadviser”) seeks to identify stocks with positive earnings trends and attractive valuations. Fundamental analysis is used to determine those companies that are projected to have sustainability of earnings and global industry positioning. The Subadviser’s goal is to find companies with top management, quality products and sound financial positions, or a history of consistent growth in cash flows, sales, operating profits, returns on equity and returns on invested capital. Risk controls are in place to assist in maintaining a portfolio that is diversified by security type and industry sector and invested across multiple countries.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company’s financial condition or overall market and economic conditions. As a result, the value of the Fund’s equity securities may fluctuate drastically from day to day.

Small-Capitalization Companies Risk: Small-cap stocks tend to perform differently from other segments of the equity market or the equity market as a whole, and can be more volatile than stocks of mid- or large-capitalization companies. Small-capitalization companies may be newer or less established and may have limited resources, products and markets, and less liquid.

Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies.

Foreign Securities Risk: Foreign securities involve special risks such as currency fluctuations, economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments. These risks are increased for investments in emerging markets. The Fund is also subject to the risk that foreign common stocks may underperform other segments of the equity market or the equity market as a whole.

Currency Risk: Changes in foreign currency exchange rates will affect the value of what the fund owns and the price of the Fund’s shares. Generally, when the U.S. dollar rises in value against a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Currency trends are unpredictable and currency rates may fluctuate significantly for a number of reasons, including changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments or central banks, or by currency controls or political developments.

Exchange-Traded Fund Risk: The risk of owning shares of an ETF generally reflects the risk of owning the underlying securities the ETF is designed to track. Liquidity in an ETF could result in more volatility than ownership of the underlying portfolio of securities. In addition, because of ETF management expenses, compared to owning the underlying securities directly, it may be more costly to own an ETF.

In selecting investments for purchase and sale, Certium Asset Management LLC (“Certium” or the “Subadviser”) uses statistical analysis in an attempt to track the Index. The Subadviser chooses companies included in the Index, which is an index of equity securities of companies located in Europe, Australasia and the Far East. While the Fund is structured to have overall investment characteristics similar to those of the Index, it selects a sample of securities within the Index using a statistical process. Therefore, the Fund will not hold all securities included in the Index.

Small- and Mid-Capitalization Companies Risk: Small- and mid-cap stocks tend to perform differently from other segments of the equity market or the equity market as a whole, and can be more volatile than stocks of large-capitalization companies. Small- and mid-capitalization companies may be newer or less established and may have limited resources, products and markets, and less liquid.

Liquidity in an ETF could result in more volatility than ownership of the underlying portfolio of securities. In addition, because of ETF management expenses, compared to owning the underlying securities directly, it may be more costly to own an ETF.

Tracking Error Risk: Because the Subadviser employs a representative sampling strategy to track the performance of the Index, the Fund’s return may not match or achieve a high degree of correlation with the return of the Index due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies.
