Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk. The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, tariffs, trade disputes, terrorism, war, armed conflicts, including related sanctions, social unrest, natural disasters, and epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Fixed-Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Fixed-Income Securities Risk. Fixed-income securities are generally subject to the following risks:•Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. •Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. •Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential. •Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall. •Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security. •Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
High-Yield Bond Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] High-Yield Bond Risk. High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. High-yield bonds are bonds rated below investment grade by Nationally Recognized Statistical Rating Organizations (“NRSROs”) or are unrated bonds considered by the Adviser to be of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
Loan Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Loan Risk. Bank loans are obligations of companies or other entities sometimes entered into in connection with recapitalizations, acquisitions, and refinancings. The Fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities. The bank loans underlying these securities often involve borrowers with low credit ratings whose financial conditions are troubled or uncertain, including companies that are highly leveraged. Loans are subject to credit risk, interest rate risk, and liquidity risk. Investments in certain commercial loans, such as bridge loans, debtor-in-possession (“DIP”) loans, and mezzanine loans subject the Fund to other risks. Bridge loans involve certain risks in addition to those associated with bank loans, including the risk that the borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness. DIP loans are subject to the risk that the entity will not emerge from bankruptcy and will be forced to liquidate its assets. Mezzanine loans generally are rated below investment grade, and frequently are unrated. Because mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure, they are subject to the additional risk that the cash flow of the related borrower and any property securing the loan may be insufficient to repay the loan after the related borrower pays off any senior obligations.
Mortgage- and Asset-Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Collateralized Loan Obligation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Collateralized Loan Obligation Risk. The risks of investing in collateralized loan obligations (“CLO”) include both the economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments. The degree of such risk will generally correspond to the specific tranche in which the Fund is invested. Higher rated tranches (such as AAA rated tranches) do not constitute a guarantee, may be downgraded, and in stressed market environments it is possible that even senior CLO tranches could experience losses due to actual defaults, increased sensitivity to defaults due to collateral default and the disappearance of the subordinated/equity tranches, market anticipation of defaults, as well as negative market sentiment with respect to CLO securities as an asset class. The Fund’s portfolio management may not be able to accurately predict how specific CLOs or the portfolio of underlying loans for such CLOs will react to changes or stresses in the market, including changes in interest rates. The most common risks associated with investing in CLOs are liquidity risk, interest rate risk, credit risk, prepayment risk, and the risk of default of the underlying asset, among others.
CLO Manager Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] CLO Manager Risk. CLOs are managed by investment advisers independent of the Adviser. CLO managers are responsible for selecting, managing and replacing the underlying bank loans or other assets within a CLO. As such, each CLO is subject to the risk that its manager may not effectively exercise its responsibilities. Adverse security selection by a CLO manager may cause a CLO to experience difficulty in making its stipulated distribution payments to investors because of the poor performance of the underlying bank loans: (i) entering into bankruptcy proceedings; and/or (ii) are in default as to the repayment of their loan balances. Generally, CLO managers mitigate these risks by maintaining a pool of underlying bank loans in excess of the minimum necessary to finance a CLO’s stipulated distribution payments. In addition, CLO managers may have limited operating histories, may be subject to conflicts of interest, including managing the assets of other clients or other investment vehicles, or receiving fees that incentivize maximizing the yield, and indirectly the risk, of a CLO. Adverse developments with respect to a CLO manager, such as personnel and resource constraints, regulatory issues or other developments that may impact the ability and/or performance of the CLO manager, may adversely impact the performance of the CLO securities in which the Fund invests.
Floating Rate Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Floating Rate Obligations Risk. The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
TBA Commitments Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] TBA Commitments Risk. Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the Fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to the Fund may be less favorable than expected. There is a risk that the security that the Fund buys will lose value between the purchase and settlement dates. TBA purchase and sales commitments may significantly increase the Fund’s portfolio turnover rate and are not included in the portfolio turnover rate calculation.
Industry and Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Industry and Sector Risk. Although the Fund does not concentrate its investments in specific industries, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector. Companies in the same industry or economic sector may be similarly affected by negative economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility. As the Fund’s holdings change over time, the Fund’s exposure to a particular economic sector may fluctuate.
Industrials Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] •Industrials Sector Risk. The industrials sector is comprised of companies that produce capital goods used in construction and manufacturing, such as companies that make and sell machinery, equipment and supplies that are used to produce other goods. Companies in the industrials sector may be adversely affected by changes in government regulation and spending, import controls, and worldwide competition. In addition, companies may be adversely affected by environmental damages, product liability claims and exchange rates, and may face product obsolescence due to rapid technological developments and frequent new product introduction.
Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Currency Risk. Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk. Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Portfolio Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Portfolio Management Risk. The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Short Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Short Exposure Risk. The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Foreign Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Exposure Risk. Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Sovereign Debt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Sovereign Debt Risk. Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent the Fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Convertible Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Convertible Securities Risk. The Fund may invest in securities that are convertible into preferred and common stocks, and thus, is subject to the risks of investments in both debt and equity securities. The market value of convertible securities tends to decline as interest rates increase and, conversely, tends to increase as interest rates decline. In addition, because of the conversion feature, the market value of convertible securities tends to vary with fluctuations in the market value of the underlying preferred and common stocks and, therefore, also will react to variations in the general market for equity securities.
Preferred Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Preferred Stock Risk. Preferred stock is subject to similar risks as common stock and debt securities. Typically, a rise in interest rates causes a decline in the value of preferred stock. Preferred stocks are also subject to credit risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payments.
Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Emerging Markets Risk. Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets, and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets.
Securities Lending Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Securities Lending Risk. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Rule 144A Securities and Other Exempt Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Rule 144A Securities and Other Exempt Securities Risk. Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
Commercial Paper Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Commercial Paper Risk. Commercial paper is a debt obligation usually issued by corporations in order to finance their current operations. Commercial paper is usually repaid at maturity by the issuer from the proceeds of the issuance of new commercial paper. As a result, investments in commercial paper are subject to the risk that the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper, also known as rollover risk. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity.
ESG Integration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ESG Integration Risk. There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different or inconsistent methodologies, or be applied differently across issuers and industries.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] The biggest risk is that the Fund’s returns and yields will vary, and you could lose money.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
