Credit Risk. Debt securities are also subject to credit risk. Credit risk is the risk that the issuer of a debt security will be unable to make interest or principal payments on time and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. A debt security’s credit rating reflects the credit risk associated with the debt obligation. Generally, higher-rated debt securities involve lower credit risk than lower-rated debt securities. Credit risk is often higher for corporate, mortgage-backed, asset-backed and foreign government debt securities than for U.S. Government debt securities.
Market Events Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Market Events Risk. The value of the Fund’s securities may increase or decrease, rapidly or unpredictably. Some factors that may affect securities markets include changes in general market conditions, overall economic trends or events, geopolitical developments (such as trade and tariff arrangements, sanctions, and cybersecurity attacks), governmental actions or intervention, threat of a U.S. government shutdown, a downgrade of the ratings of U.S. government debt obligations, actions taken by the U.S. Federal Reserve or foreign
 
central banks, market disruptions caused by trade disputes, labor strikes, political and social unrest, or other factors, recessions, armed conflict, investor sentiment, and the global and domestic effects of natural disasters and pandemics. Recently, there have been inflationary price movements, which have caused the fixed income securities markets to experience heightened levels of interest rate volatility and liquidity risk. In response to high inflation, the U.S. Federal Reserve increased interest rates in an attempt to slow economic growth, and it may continue to raise interest rates in the future. This and other changes in monetary and fiscal policy may not work as intended, particularly if the efforts are perceived by investors as being unlikely to achieve the desired results. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, labor disputes, public health events, terrorism, natural disasters, war, and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively affected.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Liquidity Risk. Some investments may be difficult to purchase or sell, particularly during times of market instability, or due to adverse changes in the conditions of a particular issuer. In addition, the Fund may not receive proceeds from the sale of certain securities for an extended period of time, which in some cases could exceed several weeks or longer. The Fund will not receive sales proceeds until settlement occurs, which may constrain the Fund’s ability to meet redemption requests or other obligations. Illiquid assets may also be difficult to value. If the Fund must sell illiquid assets to meet redemption requests or other cash needs, the Fund may be unable to sell such assets at an advantageous time or price or achieve its desired level of exposure to certain market segments. Liquidity risk may result from the lack of an active market, as well as the reduced number and capacity of traditional market participants to make a market in fixed income securities, for instance, when there are few, if any, interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. As a general matter, dealers may have less willingness to make markets for fixed income securities. Certain dealers may also reduce their inventories of certain securities in response to federal banking regulations, which may further decrease the Fund’s ability to buy or sell such securities. Liquidity risk is likely to be magnified in a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds are higher than normal.
Below Investment Grade Credit [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Below Investment Grade Credit. Below investment grade securities are speculative and involve a greater risk of default and price change due to changes in the issuer’s creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.
Foreign Investments [Member]

Risk [Text Block]
ª  
Foreign Investments. Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities. The value of the Fund’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as adverse geopolitical developments (such as trade and tariff arrangements, sanctions, and cybersecurity attacks), unfavorable or unsuccessful government actions, reduction of government or central bank support and political or financial instability. Lack of information may also affect the value, volatility and liquidity of these securities.
Derivatives [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Derivatives. The use of derivatives can lead to losses due to: (1) adverse movements in the price or value of the asset, index, rate or instrument underlying a derivative; (2) failure of a counterparty; or (3) tax or regulatory constraints. Derivatives may create economic leverage in the Fund, which magnifies the Fund’s sensitivity to market events and to the underlying instrument. Derivatives risk may be more significant when derivatives are used to enhance return or as a substitute for a cash investment position, rather than solely to hedge the risk of a position held by the Fund. When derivatives are used to gain or limit exposure to a particular market or market segment, their performance may not correlate as expected to the performance of such market thereby causing the Fund to fail to achieve its original purpose for using such derivatives. A decision as to whether, when and how to use derivatives involves the exercise of specialized skill and judgment, and a transaction may be unsuccessful in whole or in part because of market behavior or unexpected events. Derivative instruments may be difficult to value, may be illiquid, and may be subject to wide swings in valuation caused by changes in the value of the underlying instrument. If a derivative’s counterparty is unable to honor its commitments, the value of Fund shares may decline and the Fund could experience delays in the return of collateral or other assets held by the counterparty. The loss on derivative transactions may substantially exceed the initial investment. As noted above in the Principal Investment Strategies discussion, the Fund expects in particular to use credit default swaps. A principal risk of credit default swaps is the credit risk of the issuer, which is similar to a principal risk of owning a traditional bond.
Investment Company and Exchange Traded Fund Risk [Member]

Risk [Text Block]
ª  
Investment Company and Exchange-Traded Fund Risk. Investing in an investment company or ETF presents the risk that the investment company or ETF in which the Fund invests will not achieve its investment objective or execute its investment strategies effectively or that significant purchase or redemption activity by shareholders of such an investment company might negatively affect the value of the investment company’s shares.
Affiliated Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Affiliated Fund Risk. When the Adviser invests Fund assets in an investment company that is also managed by the Adviser, the risk presented is that, due to its own financial interest or other business considerations, the Adviser may have had an incentive to make that investment in lieu of investments by the Fund directly in portfolio securities, or in lieu of investment in investment companies sponsored or managed by others.
Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Redemption Risk. The Fund may experience heavy redemptions that could cause the Fund to liquidate its assets at inopportune times or at a loss or depressed value, particularly during periods of declining or illiquid markets. Redemption risk is greater to the extent that the Fund has investors with large shareholdings, short investment horizons, or unpredictable cash flow needs. In addition, redemption risk is heightened during periods of overall market turmoil. The redemption by one or more large shareholders of their holdings in the Fund could adversely affect the Fund’s performance. If the Fund is forced to liquidate its assets under unfavorable conditions or at inopportune times, the value of the Fund’s shares may decline. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs.
Management Risk [Member]

ª  
Management Risk. The investment techniques and analysis used by the Fund’s portfolio managers may not produce the desired results.
Cybersecurity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Cybersecurity Risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data, including private shareholder information, or proprietary information, cause the Fund, the Fund’s portfolio managers and/or their service providers, including, but not limited to, Fund accountants, custodians, transfer agents and financial intermediaries, to suffer data breaches, data corruption or loss of operational functionality or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The rapid development and increasingly widespread use of artificial intelligence, including machine learning technology and generative artificial intelligence, could exacerbate these risks. The Fund and the Fund’s portfolio managers have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in order to prevent any future cybersecurity incidents.
Emerging Markets [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Emerging Markets. The risks of foreign investing are heightened for securities of issuers in emerging market countries. Emerging market countries tend to have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries. In addition to all of the risks of investing in foreign developed markets, emerging markets are more susceptible to governmental interference, local taxes being imposed on foreign investments, restrictions on gaining access to sales proceeds, and less liquid and efficient trading markets.
Equity Securitiess [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Equity Securities. Investing in equity securities poses certain risks, including a sudden decline in a holding’s share price, or an overall decline in the stock market. The value of the Fund’s investment in any such securities will fluctuate on a day-to-day basis with
 
movements in the stock market, as well as in response to the activities of individual companies whose equity securities the Fund owns. Moreover, purchasing stocks perceived to be undervalued brings additional risks. For example, the issuing company’s condition may worsen instead of improve, or the pace and extent of any improvement may be less than expected.
Interest Rates [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ª  
Interest Rates. As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns usually decline. When interest rates fall, the prices of these securities usually increase. Generally, the market price of debt securities with longer maturities will fluctuate more in response to changes in interest rates than the market price of shorter-term securities. The Fund faces a heightened risk that interest rates may rise. The negative impact on fixed income securities resulting from such rate increases could be swift and significant. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions from the Fund. Factors such as government policy, inflation, the economy, and market for bonds can impact interest rates and yields.
