Portfolio Turnover [Text Block]

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 80.88% of the average value of its portfolio.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects adjustments made to the Fund's operating expenses due to the fee waiver and/or expense reimbursement by management for the 1 Year numbers only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

The Fund normally invests at least 80% of its net assets in income-producing floating interest rate corporate loans and corporate debt securities made to or issued by U.S. companies, non-U.S. entities and U.S. subsidiaries of non-U.S. entities. Floating interest rates vary with and are periodically adjusted to a generally recognized base interest rate such as the London Interbank Offered Rate (LIBOR) or the Prime Rate. The Fund may invest in companies whose financial condition is troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations or financial restructurings.

Floating interest rate corporate loans and debt securities, also called bank loans or senior floating rate interests, generally have credit ratings below investment grade and may be subject to restrictions on resale. The Fund invests at least 75% of its total assets in corporate loans and corporate debt securities that are rated B or higher by a nationally recognized statistical rating organization (NRSRO) or, if unrated, are determined to be of comparable quality by the Fund’s investment manager. The Fund may invest in corporate loans and corporate debt securities that are rated below B by an NRSRO or, if unrated, are determined to be of comparable quality by the investment manager.

In addition to the Fund’s main investments, the Fund may invest up to 20% of its net assets in certain other types of debt obligations or securities, including secured or unsecured corporate loans and corporate debt securities, and fixed rate obligations of U.S. companies, non-U.S. entities and U.S. subsidiaries of non-U.S. entities.

The Fund typically invests in a corporate loan or corporate debt security if the investment manager judges that the borrower can meet the scheduled payments on the obligation. The investment manager performs its own independent credit analysis of each borrower and of the collateral structure securing the Fund’s investment.

The Fund currently limits its investments in debt obligations of non-U.S. entities to no more than 25% of its total assets. The Fund currently invests predominately in loans or securities that are U.S. dollar-denominated or otherwise provide for payment in U.S. dollars.

To pursue its investment goals, the Fund may enter into credit default swaps (including credit default swaps based on loan or high yield indices). The use of credit default swaps may allow the Fund to obtain net long or net short exposures to select credit risks. These derivatives may be used to enhance Fund returns, obtain exposure to certain markets in a more efficient or less expensive way and/or hedge risks associated with its other portfolio investments.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.

Floating Rate Corporate Investments

The floating rate corporate loans and corporate debt securities in which the Fund invests are often issued in connection with highly leveraged transactions. Such transactions include leveraged buyout loans, leveraged recapitalization loans, and other types of acquisition financing. Leveraged buyout loans are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy. Some of these loans may be “covenant lite” loans which do not include terms which allow the lender to control and track the performance of the borrower and declare a default if certain criteria are breached.

High-Yield Debt Securities

Issuers of lower-rated or "high-yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high-yield debt securities generally fluctuate more than those of higher credit quality. High-yield debt securities are generally more illiquid (harder to sell) and harder to value.

Impairment of Collateral

The value of collateral securing a loan or other corporate debt security may decline after the Fund invests and there is a risk that the value of the collateral may not be sufficient to cover the amount owed to the Fund, or the collateral securing a loan may be found invalid, may be used to pay other outstanding obligations of the borrower under applicable law or may be difficult to sell.

Market

The market values of securities owned by the Fund will go up or down, sometimes rapidly or unpredictably. A security’s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Liquidity

From time to time, the trading market for a particular security or type of security in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities when necessary to meet the Fund’s liquidity needs or in response to a specific economic event and will also generally lower the value of a security. Market prices for such securities may be volatile.

Prepayment

Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest.

Foreign Securities

Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations. The risks of investing in foreign securities are typically greater in less developed or emerging market countries.

Derivative Instruments

The performance of derivative instruments depends largely on the performance of an underlying currency, security or index, and such instruments often have risks similar to their underlying instrument, in addition to other risks. Derivatives involve costs and can create economic leverage in the Fund's portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that exceeds the Fund's initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative instrument, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.

Interest Rate

When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these interest rate changes.

Variable Rate Securities

Because changes in interest rates on variable rate securities (including floating rate securities) may lag behind changes in market rates, the value of such securities may decline during periods of rising interest rates until their interest rates reset to market rates. If the changes in market rates are substantial, the interest rate on a variable rate security may not reset during a single adjustment period. Lifetime limits on resets may also prevent their rates from adjusting to market rates.

During periods of declining interest rates, because the interest rates on variable rate securities generally reset downward, their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

Management

The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.
