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 54% of the average value of its portfolio.

Expense Example [Heading] rr_ExpenseExampleHeading Example
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same and that you reinvest all dividends and distributions. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
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 short duration fixed income securities. These securities may include, but are 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, and repurchase agreements. The Fund's investment in foreign issuers may at times be significant.

A security's rating will be governed by the Barclays methodology as follows: when Standard & Poor's Financial Services LLC, Moody's Investors Service, Inc. and Fitch, Inc. provide a rating, Seix will assign the middle rating of the three; if only two of those three rating agencies rate the security, Seix will assign the lowest rating; if only one rating agency assigns a rating, Seix will use that rating. If none of the three provide a rating, Seix may rely on a rating provided by another nationally recognized statistical ratings organization ("NRSRO").

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. The Fund may invest a portion of its assets in securities that are restricted as to resale.

In selecting investments for purchase and sale, the Fund's Subadviser, Seix Investment Advisors LLC ("Seix" 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 credit and 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 or interest or will default. 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.

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 Companies and Securities Risk: Foreign securities and 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. Foreign securities also involve risks such as currency fluctuations and delays in enforcement of rights. All of these risks are increased for investments in emerging markets.

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, mispricing or improper valuation and that the other party to a derivative transaction will not meet its obligations. The prices of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility and unexpected losses.

A liquid secondary market may not always exist for the Fund's derivative positions at any time. In fact, many over-the-counter instruments (instruments not traded on exchange) may not be liquid. Over-the-counter instruments also involve the risk that the other party to the derivative transaction will not meet its obligations.

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 and may 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.

Restricted Securities Risk: Certain debt securities may be restricted securities, which are not registered with the SEC and thus may not be sold publicly until registration has been made. Therefore, there is the absence of a public market and there is limited investor information.

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.

U.S. Government Securities Risk: U.S. Treasury securities are backed by the full faith and credit of the U.S. government, while other types of securities issued or guaranteed by federal agencies, instrumentalities, and U.S. government-sponsored entities may or may not be backed by the full faith and credit of the U.S. government. U.S. government securities may underperform other segments of the fixed income market or the fixed income market as a whole.
