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 instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended March 31, 2019 was 69% 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 Class P Shares of the Fund for the time periods indicated and then redeem all of your Class P Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver arrangement for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in domestic or foreign floating rate loans and other floating or variable rate obligations rated below investment grade. Non-investment grade obligations are those rated BB+, Ba1 or below by a nationally recognized statistical rating organization (“NRSRO”), or, if unrated, determined by the Investment Adviser to be of comparable credit quality, and are commonly referred to as “junk bonds.” The Fund’s investments in floating and variable rate obligations may include, without limitation, senior secured loans (including assignments and participations), second lien loans, senior unsecured and subordinated loans, senior and subordinated corporate debt obligations (such as bonds, debentures, notes and commercial paper), debt issued by governments, their agencies and instrumentalities, and debt issued by central banks. The Fund may invest indirectly in loans by purchasing participations or sub-participations from financial institutions. Participations and sub-participations represent the right to receive a portion of the principal of, and all of the interest relating to such portion of, the applicable loan. The Fund expects to invest principally in the U.S. loan market and, to a lesser extent, in the European loan market. The Fund may also invest in other loan markets, although it does not currently intend to do so. Under normal conditions, the Fund may invest up to 20% of its Net Assets in fixed income instruments, regardless of rating, including fixed rate corporate bonds, government bonds, convertible debt obligations, and mezzanine fixed income instruments. The Fund may also invest in floating or variable rate instruments that are rated investment grade and in preferred stock, repurchase agreements and cash securities. The Fund may also invest in derivative instruments. Derivatives are instruments that have a value based on another instrument, exchange rate or index. The Fund’s investments in derivatives may include credit default swaps on credit and loan indices, forward contracts and total return swaps, among others. The Fund may use currency management techniques, such as forward foreign currency contracts, for hedging or non-hedging purposes. The Fund may invest in interest rate futures and swaps to manage the portfolio’s duration. Derivatives that provide exposure to floating or variable rate loans or obligations rated below investment grade are counted towards the Fund’s 80% policy. The Fund may also seek to obtain exposure to fixed income investments through investments in affiliated or unaffiliated investment companies, including exchange-traded funds (“ETFs”). The Fund’s target duration range under normal interest rate conditions is expected to approximate that of the Credit Suisse Leveraged Loan Index, plus or minus one year, and over the last five years ended June 30, 2019, the duration of the Index has ranged between 0.03 and 1.60 years. The Fund’s investments in floating rate obligations will generally have short to intermediate maturities (approximately 4-7 years). “Duration” is a measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a positive duration of 3 will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security’s market price. The Fund’s investments are selected using a bottom-up analysis that incorporates fundamental research, a focus on market conditions and pricing trends, quantitative research, and news or market events. The selection of individual investments is based on the overall risk and return profile of the investment taking into account liquidity, structural complexity, cash flow uncertainty and downside potential. Research analysts and portfolio managers systematically assess portfolio positions, taking into consideration, among other factors, broader macroeconomic conditions and industry and company-specific financial performance and outlook. Based upon this analysis, the Investment Adviser will sell positions determined to be overvalued and reposition the portfolio in more attractive investment opportunities on a relative basis given the current climate. The Fund’s benchmark index is the Credit Suisse Leveraged Loan Index.
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Conflict of Interest Risk.  Affiliates of the Investment Adviser may participate in the primary and secondary market for loan obligations. Because of limitations imposed by applicable law, the presence of the Investment Adviser’s affiliates in the loan obligations market may restrict the Fund’s ability to acquire some loan obligations or affect the timing or price of such acquisitions. Also, because the Investment Adviser may wish to invest in the publicly traded securities of a borrower, it may not have access to material non-public information regarding the borrower to which other lenders have access. Credit/Default Risk.  An issuer or guarantor of fixed income securities or instruments held by the Fund (which may have low credit ratings) may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund’s liquidity and cause significant deterioration in net asset value (“NAV”). These risks are more pronounced in connection with the Fund’s investments in non-investment grade fixed income securities. Derivatives Risk.  The Fund’s use of credit default swaps, total return swaps, futures, forwards and other derivative instruments may result in losses. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other instruments, may be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of underlying instruments may produce disproportionate losses to the Fund. Certain derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. Floating and Variable Rate Obligations Risk.  For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit the Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent the Fund from taking full advantage of rising interest rates in a timely manner. However, in a declining interest rate environment, the Fund may benefit from a lag due to an obligation’s interest rate payment not being immediately impacted by a decline in interest rates. Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the “reference rate”), such as LIBOR. Such a floor protects the Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and the Fund may not benefit from increasing interest rates for a significant amount of time. In 2017, the United Kingdom’s Financial Conduct Authority (“FCA”) warned that LIBOR may cease to be available or appropriate for use by 2021. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain Fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any pricing adjustments to a Fund’s investments resulting from a substitute reference rate may also adversely affect the Fund’s performance and/or NAV. Foreign Risk.  Foreign investments may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls (including repatriation restrictions), sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States or other governments, or from problems in share registration, settlement or custody, may also result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of instruments denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Liquidity Risk.  The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests or other reasons. To meet redemption requests, the Fund may be forced to sell investments at an unfavorable time and/or under unfavorable conditions. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity. Redemptions by large shareholders may have a negative impact on the Fund’s liquidity. Loan-Related Investments Risk.  In addition to risks generally associated with debt investments (e.g., interest rate risk and default risk), loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be or become illiquid or less liquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and certain loan investments may be or become illiquid or less liquid and more difficult to value, particularly in the event of a downgrade of the loan or the borrower. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, the Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Fund to the creditworthiness of that lender as well. Investors in loans, such as the Fund, may not be entitled to rely on the anti-fraud protections of the federal securities laws, although they may be entitled to certain contractual remedies. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund’s redemption obligations for a period after the sale of the loans, and, as a result, the Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations. During periods of heightened redemption activity or distressed market conditions, the Fund may seek to obtain expedited trade settlement, which will generally incur additional costs (although expedited trade settlement will not always be available). Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid. Generally, loans have the benefit of restrictive covenants that limit the ability of the borrower to further encumber its assets or impose other obligations. To the extent a loan does not have certain covenants (or has less restrictive covenants), an investment in the loan will be particularly sensitive to the risks associated with loan investments. Non-Investment Grade Fixed Income Securities Risk.  Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as “junk bonds”) are considered speculative and are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity. Other Investment Companies Risk.  By investing in other investment companies (including ETFs) indirectly through the Fund, investors will incur a proportionate share of the expenses of the other investment companies held by the Fund (including operating costs and investment management fees) in addition to the fees regularly borne by the Fund. In addition, the Fund will be affected by the investment policies, practices and performance of such investment companies in direct proportion to the amount of assets the Fund invests therein.
