Investment Objectives and Practices [Text Block]		Investment Objectives, Principal Investment Strategies and Principal Risks CHANGES OCCURRING DURING THE MOST RECENT FISCAL YEAR During the Fund’s most recent fiscal year, there were no material changes to the Fund’s investment objectives or policies that have not been approved by stockholders or in the principal risk factors associated with investment in the Fund. INVESTMENT OBJECTIVES The Fund’s primary investment objective is to provide a high level of current income. As a secondary investment objective, the Fund seeks preservation of capital to the extent consistent with its primary investment objective. The Fund’s investment objectives are fundamental policies and may not be changed without the approval of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund. There can be no assurance that the Fund will achieve its investment objectives. PRINCIPAL INVESTMENT STRATEGIES As a fundamental policy, under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its assets (net assets plus borrowings for investment purposes) in senior floating rate loans (“Senior Loans”). Senior Loans typically are made to corporations, partnerships and other business entities that operate in various industries and geographical regions, including non-U.S. borrowers. The Fund also may invest in other floating and variable rate instruments, including second lien loans, and in high yield corporate bonds, investment grade fixed-income debt securities, preferred stocks (many of which have fixed maturities), convertible securities, securities that make “in-kind” interest payments, bonds not paying current income, bonds that do not make regular interest payments and money market instruments. Senior Loans and other floating rate instruments pay interest at rates that adjust or “float” periodically based on a specified interest rate or other reference. The Fund does not have a policy of maintaining a specific average credit quality of its portfolio or a minimum portion of its portfolio that must be rated investment grade. The Fund may invest up to 35% of its assets (net assets plus borrowings for investment purposes) in floating rate loans and other securities of non-U.S. issuers, including emerging markets securities. The Fund does not expect that investments in second lien loans generally will exceed 15% of its assets. The Fund may invest in Senior Loans and other securities of any credit quality, including Senior Loans and other investments that are rated below investment grade, or are unrated but are determined by the Adviser to be of equivalent credit quality. Non-investment grade securities, commonly referred to as junk bonds, are obligations that are rated below investment grade by the national rating agencies that cover the obligations (i.e., Ba and below by Moody’s Investors Service, Inc. (“Moody’s”) or BB and below by Standard & Poor’s Ratings Group (“S&P”)), or if unrated, are determined by the Adviser to be of comparable quality. Investment in securities of below investment grade quality involves substantial risk of loss. “Junk bonds” are considered predominantly speculative with respect to the issuer’s ability to pay interest and repay principal and are susceptible to default or decline in market value due to adverse economic and business developments. Floating rate loans typically are rated below investment grade. Accordingly, a substantial portion of the Fund’s assets may be invested in securities that are rated below investment grade or are unrated. The Fund may invest all or any portion of its assets in securities of issuers that are in default or that are in bankruptcy. The Fund may consider another fund, such as an exchange-traded fund (ETF), as Senior Loans for purposes of satisfying the Fund’s 80% policy, if the Fund invests at least 80% of its assets in Senior Loans. The Adviser considers both broad economic and issuer specific factors in selecting a portfolio designed to achieve the Fund’s investment objectives. The Adviser selects individual securities based upon the terms of the securities (such as yields compared to U.S. Treasuries or comparable issues, or rates such as LIBOR or SOFR), liquidity and rating, sector and exposure to particular issuers and sectors. The Adviser also employs fundamental research to assess an issuer’s credit quality, taking into account financial condition and profitability, future capital needs, potential for change in rating agency recommendations, industry outlook, the competitive environment and management ability. In making these portfolio decisions, the Adviser relies on the knowledge, experience and judgment of its staff and the staff of its affiliates who have access to a wide variety of research. The Fund may, but is not required to, use various hedging and interest rate transactions to earn income, facilitate portfolio management and mitigate risks. The Fund may purchase and sell derivative instruments such as exchange-listed and over-the-counter put and call options on securities, fixed income and interest rate indices and other financial instruments; purchase and sell financial futures contracts and options thereon; and enter into various interest rate transactions such as swaps, caps, floors or collars or credit transactions and credit default swaps. The Fund also may purchase derivative instruments that combine features of these instruments. The Fund generally seeks to use these instruments and transactions as a portfolio management or hedging technique that seeks to protect against possible adverse changes in the market value of loans or other securities held in or to be purchased for the Fund’s portfolio, to facilitate the sale of certain securities for investment purposes, manage the effective interest rate exposure of the Fund, manage the effective maturity or duration of the Fund’s portfolio or establish positions in the derivatives markets as a temporary substitute for purchasing or selling particular securities. The Fund may use financial leverage on an ongoing basis for investment purposes by borrowing from banks through a revolving credit facility. Leverage creates special risks not associated with unleveraged funds having a similar investment objectives and policies. These include the possibility of higher volatility of both the net asset value of the Fund and the value of assets serving as asset coverage for the borrowing. The fees and expenses attributed to leverage, including any increase in the management fees, will be borne by holders of common shares. The Adviser intends only to leverage the Fund when it believes that the potential total return on additional investments purchased with the proceeds of leverage is likely to exceed the costs incurred in connection with the leverage. The Fund may not be leveraged at all times, and the amount of leverage, if any, may vary depending on a variety of factors, including the Adviser’s outlook for interest rates and credit markets and the costs that the Fund would incur as a result of such leverage. The Fund’s leveraging strategy may not be successful. Interest rates on Senior Loans and other securities in which the Fund invests adjust periodically. The interest rates are adjusted based on a base rate plus a premium or spread over the base rate. The Adviser expects that the average effective duration of the Fund’s portfolio of Senior Loans will normally be between zero and two years, reflecting the Fund’s focus on floating rate instruments. Unlike maturity, duration takes into account interest payments that occur throughout the course of holding the instrument. The longer a portfolio’s duration, the more sensitive it will be to changes in interest rates. For example, if the Fund has a two year duration, then all other things being equal, the Fund will decrease in value by two percent if interest rates rise one percent. The assumptions that are made about an instrument’s features and options when calculating duration may prove to be incorrect. Duration is calculated by the Adviser, is not an exact measurement and may not reliably predict the Fund’s or a particular security’s price sensitivity to changes in yield or interest rates. Because the interest rate on Senior Loans held by the Fund will reset at short-term intervals, the duration of Senior Loans will be shorter than that of a fixed income security with a comparable term to maturity. The Adviser’s staff monitors the credit quality and price of Senior Loans and other securities held by the Fund. The Fund may invest in Senior Loans and other securities of any credit quality, including Senior Loans and other investments that are rated below investment grade or are unrated but are determined by the Adviser to be of equivalent credit quality. The Fund does not have a policy of maintaining a specific average credit quality of its portfolio nor a minimum portion of its portfolio that must be rated investment grade. Although the Adviser considers ratings when making investment decisions, it performs its own credit and investment analysis and does not rely primarily on ratings assigned by rating services. Except for the Fund’s investment objectives and the Fund’s policy to invest at least 80% of its assets in Senior Loans, the Fund’s investment strategies and policies may be changed from time to time without stockholder approval, unless specifically stated otherwise. Other Investments. Normally, the Fund will invest substantially all of its assets to meet its investment objectives. The Fund may invest the remainder of its assets in securities with remaining maturities of less than one year or cash equivalents, or it may hold cash. For temporary defensive purposes, the Fund may depart from its principal investment strategies and invest part or all of its assets in securities with remaining maturities of less than one year or cash equivalents, or it may hold cash. During such periods, the Fund may not be able to achieve its investment objectives. Portfolio Contents Floating rate instruments. Floating rate instruments pay interest rates that adjust or “float” periodically based on a specified interest rate or other reference and include floating rate loans, repurchase agreements, money market securities and shares of money market and short-term bond funds. Floating rate loans. Floating rate loans are provided by banks and other financial institutions to large corporate customers in connection with recapitalizations, acquisitions, and refinancings. These loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These loans are rated below investment grade. The rates of interest on the loans typically adjust periodically by reference to a base lending rate, such as the Secured Overnight Financing Rate (SOFR), a designated U.S. bank’s prime or base rate or the overnight federal funds rate, plus a premium. Some loans reset on set dates, typically every 30 to 90 days, but not to exceed one year. Other loans reset periodically when the underlying rate resets. Senior loans hold a senior position in the capital structure of the borrower. Having a senior position means that, if the borrower becomes insolvent, senior debtholders, like the Fund, will be paid before subordinated debtholders and stockholders of the borrower. Senior loans typically are secured by specific collateral. Floating rate loans typically are structured and administered by a financial institution that acts as an agent for the holders of the loan. Loans can be acquired directly through the agent, by assignment from another holder of the loan, or as a participation interest in the loan. When the Fund is a direct investor in a loan, the Fund may have the ability to influence the terms of the loan, although the Fund does not act as the sole negotiator or originator of the loan. Participation interests are fractional interests in a loan issued by a lender or other financial institution. When the Fund invests in a loan participation, the Fund does not have a direct claim against the borrower and must rely upon an intermediate participant to enforce any rights against the borrower. The Fund may invest up to 35% of its total assets in floating rate loans and other securities of non-U.S. issuers, including emerging market issuers, and may engage in certain hedging transactions. Borrowers may have outstanding debt obligations that are rated below investment grade by a rating agency. A high percentage of loans held by the Fund may be rated below investment grade by independent rating agencies. In the event loans are not rated, they are likely to be the equivalent of below investment grade quality. Debt securities which are unsecured and rated below investment grade (i.e., Ba and below by Moody’s or BB and below by S&P) and comparable unrated bonds, are viewed by the rating agencies as having speculative characteristics and are commonly known as “junk bonds.” The Fund may hold securities that are unrated or in the lowest ratings categories (rated C by Moody’s or D by S&P). Debt securities rated C by Moody’s are regarded as having extremely poor prospects of ever attaining any real investment standing. Debt securities rated D by S&P are in payment default or a bankruptcy petition has been filed and debt service payments are jeopardized. In order to enforce its rights with defaulted securities, the Fund may be required to retain legal counsel and/or a financial adviser. The Fund may have to pursue legal remedies, the results of which are uncertain and expensive. This may increase operating expenses and adversely affect net asset value. Second lien loans and other subordinated securities. The Fund may invest in second lien loans and other securities that are subordinated or “junior” to more senior securities of the issuer. The investor in a subordinated security of an issuer is entitled to payment after other holders of debt in that issuer. Other Fixed Income Securities. The Fund also may purchase unsecured loans, other floating rate debt securities such as notes, bonds and asset-backed securities (such as securities issued by special purpose funds investing in bank loans), investment grade and below investment grade fixed income debt obligations and money market instruments, such as commercial paper. The Fund may invest in zero coupon bonds, deferred interest bonds and bonds or preferred stocks on which the interest is payable in-kind (PIK bonds). Non-U.S. Investments. The Fund may invest in securities of non-U.S. issuers, including securities of emerging markets issuers. Non-U.S. issuers are issuers that are organized and have their principal offices outside of the United States. Non-U.S. securities may be issued by non-U.S. governments, banks or corporations, or private issuers, and certain supranational organizations, such as the World Bank and the European Union. The Fund considers emerging market issuers to include issuers organized under the laws of an emerging market country, issuers with a principal office in an emerging market country, issuers that derive at least 50% of their gross revenues or profits from goods or services produced in emerging market countries or sales made in emerging market countries, or issuers that have at least 50% of their assets in emerging market countries and emerging market governmental issuers. Emerging markets generally will include, but not be limited to, countries included in the Morgan Stanley Capital International (MSCI) Emerging + Frontier Markets Index. Mortgage-Backed Securities. The Fund may invest in mortgage-backed securities. Mortgage-backed securities may be issued by private issuers, by government-sponsored entities such as FNMA or FHLMC or by agencies of the U.S. government, such as GNMA. Mortgage-backed securities represent direct or indirect participation in, or are collateralized by and payable from, mortgage loans secured by real property. The Fund’s investments in mortgage-related securities may include mortgage derivatives and structured securities. The Fund may invest in collateralized mortgage obligations (CMOs). A CMO is a mortgage-backed bond that is issued in multiple classes, each with a specified fixed or floating interest rate and a final scheduled distribution date. The holder of an interest in a CMO is entitled to receive specified cash flows from a pool of underlying mortgages or other mortgage-backed securities. Depending upon the class of CMO purchased, the holder may be entitled to payment before the cash flow from the pool is used to pay holders of other classes of the CMO or, alternatively, the holder may be paid only to the extent that there is cash remaining after the cash flow has been used to pay other classes. A subordinated interest may serve as a credit support for the senior securities purchased by other investors. The Fund may invest in commercial mortgage-backed securities (“CMBS”). CMBS are subject to the risks generally associated with mortgage-backed securities. CMBS may not be backed by the full faith and credit of the U.S. government and are subject to risk of default on the underlying mortgages. CMBS issued by non-government entities may offer higher yields than those issued by government entities, but also may be subject to greater volatility than government issues. CMBS react differently to changes in interest rates than other bonds and the prices of CMBS may reflect adverse economic and market conditions. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of CMBS. The commercial mortgages underlying certain commercial mortgage-backed securities generally allow all or a substantial portion of the loan balance to be paid at maturity, commonly known as a balloon payment. Some mortgage loans restrict periodic adjustments by limiting changes in the borrower’s monthly principal and interest payments rather than limiting interest rate changes. These payment caps may result in negative amortization, where payments are less than the amount of principal and interest owed, with excess amounts added to the outstanding principal balance, which can extend the average life of the mortgage-backed securities. The Fund may invest in credit risk transfer securities. Credit risk transfer securities are a type of mortgage-related security that transfers the credit risk related to certain types of mortgage-backed securities to the owner of the credit risk transfer security. Credit risk transfer securities are commonly issued by government-sponsored enterprises (GSEs), such as FNMA or FHLMC, but may also be issued by private entities such as banks or other financial institutions. Credit risk transfer securities issued by GSEs are unguaranteed and unsecured fixed or floating rate general obligations and are typically issued at par and have stated final maturities. In addition, GSE-issued credit risk transfer securities are structured so that: (i) interest is paid directly by the issuing GSE; and (ii) principal is paid by the issuing GSE in accordance with the principal payments and default performance of a pool of residential mortgage loans acquired by the GSE. In this regard, holders of GSE credit risk transfer securities receive compensation for providing credit protection to the GSE and, when a specified level of losses on the underlying mortgage loans occurs, the principal balance and certain payments owed to the holders of such GSE credit risk transfer securities may be reduced. In the event that a government-sponsored enterprise fails to pay principal or interest on its credit risk transfer securities or goes through a bankruptcy, insolvency or similar proceeding, holders of such credit risk transfer securities have no direct recourse to the underlying mortgage loans and will generally receive recovery on par with other unsecured note holders in such a scenario. The risks associated with an investment in credit risk transfer securities are different than the risks associated with an investment in mortgage-backed securities issued by FNMA and FHLMC, or other government-sponsored enterprise or issued by a private issuer, because some or all of the mortgage default or credit risk associated with the underlying mortgage loans is transferred to investors. As a result, investors in these securities could lose some or all of their investment in these securities if the underlying mortgage loans default. Asset-Backed Securities. The Fund may invest in asset-backed securities. Asset-backed securities represent participations in, or are secured by and payable from, assets such as installment sales or loan contracts, leases, credit card receivables and other categories of receivables. The Fund’s investments in asset-backed securities may include derivative and structured securities. The Fund may invest in asset-backed securities issued by special entities, such as trusts, that are backed by a pool of financial assets. The Fund may invest in collateralized debt obligations (CDOs), which include collateralized bond obligations (CBOs), collateralized loan obligations (CLOs) and other similarly structured securities. A CDO is a trust backed by a pool of fixed income securities. The trust typically is split into two or more portions, called tranches, which vary in credit quality, yield, credit support and right to repayment of principal and interest. Lower tranches pay higher interest rates but represent lower degrees of credit quality and are more sensitive to the rate of defaults in the pool of obligations. Certain CDOs may use derivatives, such as credit default swaps, to create synthetic exposure to assets rather than holding such assets directly. Insurance-Linked Securities. The Fund may invest in insurance-linked securities (ILS). The Fund could lose a portion or all of the principal it has invested in an ILS, and the right to additional interest or dividend payments with respect to the security, upon the occurrence of one or more trigger events, as defined within the terms of an insurance-linked security. Trigger events, generally, are hurricanes, earthquakes, or other natural events of a specific size or magnitude that occur in a designated geographic region during a specified time period, and/or that involve losses or other metrics that exceed a specific amount. There is no way to accurately predict whether a trigger event will occur, and accordingly, ILS carry significant risk. The Fund is entitled to receive principal and interest and/or dividend payments so long as no trigger event occurs of the description and magnitude specified by the instrument. In addition to the specified trigger events, ILS may expose the Fund to other risks, including but not limited to issuer (credit) default, adverse regulatory or jurisdictional interpretations and adverse tax consequences. The Fund’s investments in ILS may include event-linked bonds. ILS also may include securities issued by special purpose vehicles (“SPVs”) or similar instruments structured to comprise a portion of a reinsurer’s catastrophe-oriented business, known as quota share instruments (sometimes referred to as reinsurance sidecars), or to provide reinsurance relating to specific risks to insurance or reinsurance companies through a collateralized instrument, known as collateralized reinsurance. Structured reinsurance investments also may include industry loss warranties (“ILWs”). A traditional ILW takes the form of a bilateral reinsurance contract, but there are also products that take the form of derivatives, collateralized structures, or exchange-traded instruments. The Fund may invest in interests in pooled entities that invest primarily in ILS. Where the ILS are based on the performance of underlying reinsurance contracts, the Fund has limited transparency into the individual underlying contracts, and therefore must rely upon the risk assessment and sound underwriting practices of the issuer. Accordingly, it may be more difficult for the Adviser to fully evaluate the underlying risk profile of the Fund’s structured reinsurance investments, and therefore the Fund’s assets are placed at greater risk of loss than if the Adviser had more complete information. Structured reinsurance instruments generally will be considered illiquid securities by the Fund. Zero Coupon Securities . The Fund may invest in zero coupon securities. Zero coupon securities are debt instruments that do not pay interest during the life of the security but are issued at a discount from the amount the investor will receive when the issuer repays the amount borrowed (the face value). The discount approximates the total amount of interest that would be paid at an assumed interest rate. Derivatives. The Fund may, but is not required to, use futures and options on securities, indices and currencies, forward foreign currency exchange contracts, swaps, credit-linked notes and other derivatives. The Fund also may enter into credit default swaps, which can be used to acquire or to transfer the credit risk of a security or index of securities without buying or selling the security or securities comprising the relevant index. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. The Fund may use derivatives for a variety of purposes, including: • In an attempt to hedge against adverse changes in the market prices of securities, interest rates or currency exchange rates • As a substitute for purchasing or selling securities • To attempt to increase the Fund’s return as a non-hedging strategy that may be considered speculative • To manage portfolio characteristics (for example, the duration or credit quality of the Fund’s portfolio) • As a cash flow management technique The Fund may choose not to make use of derivatives for a variety of reasons, and any use may be limited by applicable law and regulations. Common Stocks. The Fund may acquire an interest in common stocks upon the default of a loan or other security secured by such common stock. The Fund may also acquire warrants or other rights to purchase a borrower’s common stock in connection with the making of a loan. Common stocks are shares of a corporation or other entity that entitle the holder to a pro rata share of the profits, if any, of the corporation without preference over any other stockholder or class of stockholders, including holders of such entity’s preferred stock and other senior equity securities. Common stock usually carries with it the right to vote and frequently an exclusive right to do so. In selecting common stocks for investment, the Fund generally expects to focus primarily on the security’s dividend paying capacity rather than on its potential for capital appreciation. Preferred Stocks. The Fund may invest in preferred securities. Preferred securities are equity securities, but they have many characteristics of fixed income securities, such as a fixed dividend payment rate and/or a liquidity preference over the issuer’s common shares. However, because preferred shares are equity securities, they may be more susceptible to risks traditionally associated with equity investments than the Fund’s fixed income securities. Convertible Securities. The Fund’s investment in fixed income securities may include bonds and preferred stocks that are convertible into the equity securities of the issuer or a related company. Depending on the relationship of the conversion price to the market value of the underlying securities, convertible securities may trade more like equity securities than debt instruments. Other Debt Securities. The Fund may invest in other debt securities. Other debt securities in which the Fund may invest include: securities issued or guaranteed by the U.S. government, its agencies or instrumentalities and custodial receipts therefor; securities issued or guaranteed by a foreign government or any of its political subdivisions, authorities, agencies or instrumentalities or by international or supranational entities; corporate debt securities, including notes, bonds and debentures; certificates of deposit and bankers’ acceptances issued or guaranteed by, or time deposits maintained at, banks (including U.S. or foreign branches of U.S. banks or U.S. or foreign branches of foreign banks) having total assets of more than $1 billion; commercial paper; and mortgage related securities. These securities may be of any maturity. The value of debt securities can be expected to vary inversely with interest rates. Money Market Instruments. Money market instruments include short-term U.S. government securities, U.S. dollar-denominated, high quality commercial paper (unsecured promissory notes issued by corporations to finance their short-term credit needs), certificates of deposit, bankers’ acceptances and repurchase agreements relating to any of the foregoing. U.S. government securities include Treasury notes, bonds and bills, which are direct obligations of the U.S. government backed by the full faith and credit of the United States and securities issued by agencies and instrumentalities of the U.S. government, which may be guaranteed by the U.S. Treasury, may be supported by the issuer’s right to borrow from the U.S. Treasury or may be backed only by the credit of the federal agency or instrumentality itself. Other Investment Companies. The Fund may invest in the securities of other investment companies to the extent that such investments are consistent with the Fund’s investment objectives and principal investment strategies and permissible under the 1940 Act. Subject to the limitations on investment in other investment companies, the Fund may invest in “ETFs.” Repurchase Agreements. In a repurchase agreement, the Fund purchases securities from a broker/dealer or a bank, called the counterparty, upon the agreement of the counterparty to repurchase the securities from the Fund at a later date, and at a specified price, which is typically higher than the purchase price paid by the Fund. The securities purchased serve as the Fund’s collateral for the obligation of the counterparty to repurchase the securities. If the counterparty does not repurchase the securities, the Fund is entitled to sell the securities, but the Fund may not be able to sell them for the price at which they were purchased, thus causing a loss. Additionally, if the counterparty becomes insolvent, there is some risk that the Fund will not have a right to the securities, or the immediate right to sell the securities.
Risk Factors [Table Text Block]		PRINCIPAL RISKS General. The Fund is a closed-end management investment company designed primarily as a long-term investment and not as a trading tool. The Fund is not a complete investment program and should be considered only as an addition to an investor’s existing portfolio of investments. Because the Fund may invest substantially in high yield debt securities, an investment in the Fund’s shares is speculative in that it involves a high degree of risk. Due to uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objective. Instruments in which the Fund invests may only have limited liquidity, or may be illiquid. Market price of shares . Common shares of closed-end funds frequently trade at a price lower than their net asset value. This is commonly referred to as “trading at a discount.” This characteristic of shares of closed-end funds is a risk separate and distinct from the risk that the Fund’s net asset value may decrease. Both long and short-term investors, including investors who sell their shares within a relatively short period after purchase, will be exposed to this risk. The Fund is designed primarily for long-term investors and should not be considered a vehicle for trading purposes. Whether investors will realize a gain or loss upon the sale of the Fund’s Common Shares will depend upon whether the market value of the shares at the time of sale is above or below the price the investor paid, taking into account transaction costs, for the shares and is not directly dependent upon the Fund’s net asset value. Because the market value of the Fund’s shares will be determined by factors such as the relative demand for and supply of the shares in the market, general market conditions and other factors beyond the control of the Fund, the Fund cannot predict whether its Common Shares will trade at, below or above net asset value, or below or above the offering price for the shares. Market risk. The market prices of securities or other assets held by the Fund may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political, or regulatory conditions, political instability, recessions, inflation, changes in interest or currency rates, lack of liquidity in the bond markets, the spread of infectious illness or other public health issues, weather or climate crisis, armed conflict, market disruptions caused by tariffs, trade disputes, sanctions or other government actions, or other factors or adverse investor sentiment. If the market prices of the Fund’s securities and assets fall, the value of your investment will go down. A change in financial condition or other event affecting a single issuer or market may adversely impact securities markets as a whole. Changes in market conditions may not have the same impact on all types of securities. The value of securities may also fall due to specific conditions that affect a particular sector of the securities market or a particular issuer. In the past decade, financial markets throughout the world have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. Governmental and non-governmental issuers have defaulted on, or been forced to restructure, their debts. These conditions may continue, recur, worsen or spread. Events that have contributed to these market conditions include, but are not limited to, major cybersecurity events; geopolitical events (including wars, terror attacks and economic sanctions); measures to address budget deficits; downgrading of sovereign debt; changes in oil and commodity prices; dramatic changes in currency exchange rates; global pandemics; and public sentiment. The long-term impact of the COVID-19 pandemic and its subsequent variants on economies, markets, industries and individual issuers, are not known. Some sectors of the economy and individual issuers have experienced or may experience particularly large losses. Periods of extreme volatility in the financial markets, reduced liquidity of many instruments, increased government debt, inflation, and disruptions to supply chains, consumer demand and employee availability, may continue for some time. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. Inflation and interest rates have increased and may rise further. These circumstances could adversely affect the value and liquidity of the Fund’s investments and negatively impact the Fund’s performance. In addition, inflation, rising interest rates, global supply chain disruptions and other market events could adversely affect the companies or issuers in which the Fund invests. Following Russia’s invasion of Ukraine, Russian securities lost all, or nearly all, their market value. Other securities or markets could be similarly affected by past or future political, geopolitical or other events or conditions. Governments and central banks, including the U.S. Federal Reserve, have taken extraordinary and unprecedented actions to support local and global economies and the financial markets. These actions have resulted in significant expansion of public debt, including in the U.S. The consequences of high public debt, including its future impact on the economy and securities markets, may not be known for some time. U.S. Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including increases or decreases in interest rates, or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation, and these and other events affecting global markets, such as the United Kingdom’s exit from the European Union (or Brexit), potential trade imbalances with China or other countries, or sanctions or other government actions against Russia, other nations or individuals or companies (or their countermeasures), may contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes on the markets, and the implications for market participants, may not be fully known for some time. The U.S. and other countries are periodically involved in disputes over trade and other matters, which may result in tariffs, investment restrictions and adverse impacts on affected companies and securities. For example, the U.S. has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the U.S. and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The U.S. government has prohibited U.S. persons, such as the Fund, from investing in Chinese companies designated as related to the Chinese military. These and possible future restrictions could limit the Fund’s opportunities for investment and require the sale of securities at a loss or make them illiquid. Moreover, the Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the U.S. and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the Fund’s assets may go down. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, armed conflict such as between Russia and Ukraine or in the Middle East, terrorism, natural disasters, infectious illness or public health issues, cybersecurity events, supply chain disruptions, sanctions against Russia, other nations or individuals or companies and possible countermeasures, and other circumstances in one country or region could have profound impacts on other countries or regions and 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. The Fund may experience a substantial or complete loss on any individual security or derivative position. Until recently, a commonly used reference rate for floating rate securities was LIBOR (London Interbank Offered Rate). ICE Benchmark Administration, the administrator of LIBOR, has ceased publication of most LIBOR settings on a representative basis. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in most major currencies. In the U.S., a common benchmark replacement is based on the Secured Overnight Financing Rate (SOFR) published by the Federal Reserve Bank of New York, including certain spread adjustments and benchmark replacement conforming changes, although other benchmark replacements (with or without spread adjustments) may be used in certain transactions. The impact of the transition from LIBOR on the Fund’s transactions and financial markets generally cannot yet be determined. The transition away from LIBOR may lead to increased volatility and illiquidity in markets for instruments that have relied on LIBOR and may adversely affect the Fund’s performance. High yield or “junk” bond risk . Debt securities that are below investment grade, called “junk bonds,” are speculative, have a higher risk of default or are already in default, tend to be less liquid and are more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments. These risks are more pronounced for securities that are already in default. Interest rate risk. The market prices of the Fund’s fixed income securities may fluctuate significantly when interest rates change. The value of your investment will generally go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term or duration securities. For example, if interest rates increase by 1%, the value of a Fund’s portfolio with a portfolio duration of ten years would be expected to decrease by 10%, all other things being equal. In recent years interest rates and credit spreads in the U.S. have been at historic lows. The U.S. Federal Reserve has raised certain interest rates, and interest rates may continue to go up. A general rise in interest rates could adversely affect the price and liquidity of fixed income securities. The maturity of a security may be significantly longer than its effective duration. A security’s maturity and other features may be more relevant than its effective duration in determining the security’s sensitivity to other factors affecting the issuer or markets generally, such as changes in credit quality or in the yield premium that the market may establish for certain types of securities (sometimes called “credit spread”). In general, the longer its maturity the more a security may be susceptible to these factors. When the credit spread for a fixed income security goes up, or “widens,” the value of the security will generally go down. Rising interest rates can lead to increased default rates, as issuers of floating rate securities find themselves faced with higher payments. Unlike fixed rate securities, floating rate securities generally will not increase in value if interest rates decline. Changes in interest rates also will affect the amount of interest income the Fund earns on its floating rate investments. Credit risk. If an issuer or guarantor of a security held by the Fund or a counterparty to a financial contract with the Fund defaults on its obligation to pay principal and/or interest, has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines, the value of your investment will typically decline. Changes in actual or perceived creditworthiness may occur quickly. The Fund could be delayed or hindered in its enforcement of rights against an issuer, guarantor or counterparty. Prepayment or call risk. Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the Fund will not benefit from the rise in market price that normally accompanies a decline in interest rates, and will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The Fund also may lose any premium it paid on the security. Extension risk. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected principal payments. This may lock in a below market interest rate, increase the security’s duration and reduce the value of the security. Risk of illiquid investments. Certain securities and derivatives held by the Fund may be impossible or difficult to purchase, sell or unwind. Illiquid securities and derivatives also may be difficult to value. Liquidity risk may be magnified in an environment of rising interest rates or widening credit spreads. During times of market turmoil, there have been, and may be, no buyers or sellers for securities in entire asset classes. If the Fund is forced to sell an illiquid asset or unwind a derivatives position, the Fund may suffer a substantial loss or may not be able to sell at all. Portfolio selection risk. The Adviser’s judgment about the quality, relative yield, relative value or market trends affecting a particular sector or region, market segment, security, industry or about interest rates or other market factors may prove to be incorrect or may not produce the desired results, or there may be imperfections, errors or limitations in the models, tools and information used by the Adviser. Reinvestment risk. Income from the Fund’s portfolio will decline if the Fund invests the proceeds, repayment or sale of loans or other obligations into lower yielding instruments with a lower spread over the base lending rate. A decline in income could affect the common shares’ distribution rate and their overall return. Risks of investing in floating rate loans. Floating rate loans and similar investments may be illiquid or less liquid than other investments and difficult to value. Market quotations for these securities may be volatile and/or subject to large spreads between bid and ask prices. No active trading market may exist for many floating rate loans, and many loans are subject to restrictions on resale. Any secondary market may be subject to irregular trading activity and extended trade settlement periods. An economic downturn generally leads to a higher non-payment rate, and a loan may lose significant value before a default occurs. When the Fund invests in a loan participation, the Fund does not have a direct claim against the borrower and must rely upon an intermediate participant to enforce any rights against the borrower. As a result, the Fund is subject to the risk that an intermediate participant between the Fund and the borrower will fail to meet its obligations to the Fund, in addition to the risk that the issuer of the loan will default on its obligations. Also, the Fund may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Fund to the creditworthiness of the lender as well as the borrower. There is less readily available, reliable information about most senior loans than is the case for many other types of securities. Although the features of senior loans, including being secured by collateral and having priority over other obligations of the issuer, reduce some of the risks of investment in below investment grade securities, the loans are subject to significant risks. the Adviser believes, based on its experience, that senior floating rate loans generally have more favorable loss recovery rates than most other types of below investment grade obligations. However, there can be no assurance that the Fund’s actual loss recovery experience will be consistent with the Adviser’s prior experience or that the senior loans in which the Fund invests will achieve any specific loss recovery rate. The types of covenants included in loan agreements generally vary depending on market conditions, the creditworthiness of the issuer, the nature of the collateral securing the loan, and other factors. Loans may have restrictive covenants that limit the ability of a borrower to further encumber its assets. If a borrower fails to comply with the covenants included in a loan agreement, the borrower may default in payment of the loan. Some of the loans in which the Fund may invest may be “covenant lite.” Covenant lite loans contain fewer maintenance covenants, or no maintenance covenants at all, than traditional loans and may not include terms that allow the lender to monitor the financial performance of the borrower and declare a default if certain criteria are breached. This may expose the Fund to greater credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result the Fund’s exposure to losses on such investments may be increased, especially during a downturn in the credit cycle. Second lien loans generally are subject to similar risks as those associated with senior loans. Because second lien loans are subordinated or unsecured and thus lower in priority on 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. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Second lien loans generally have greater price volatility than senior loans and may be less liquid. Certain floating rate loans and other corporate debt securities involve refinancings, recapitalizations, mergers and acquisitions, and other financings for general corporate purposes. Other loans are incurred in restructuring or “work-out” scenarios, including debtor-in-possession facilities in bankruptcy. Loans in restructuring or similar scenarios may be especially vulnerable to the inherent uncertainties in restructuring processes. In addition, the highly leveraged capital structure of the borrowers in any of these transactions, whether acquisition financing or restructuring, may make the loans especially vulnerable to adverse economic or market conditions and the risk of default. Loans to entities located outside of the U.S. may have substantially different lender protections and covenants as compared to loans to U.S. entities and may involve greater risks. The Fund may have difficulties and incur expense enforcing its rights with respect to non-U.S. loans and such loans could be subject to bankruptcy laws that are materially different than in the U.S. Because affiliates of the Adviser may participate in the primary and secondary market for senior loans, limitations under applicable law may restrict the Fund’s ability to participate in a restructuring of a senior loan or to acquire some senior loans, or affect the timing or price of such acquisition. Loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections afforded by federal securities laws. Collateral risk. The value of collateral, if any, securing a floating rate loan can decline, and may be insufficient to meet the issuer’s obligations or may be difficult to liquidate. In addition, the Fund’s access to collateral may be limited by bankruptcy or other insolvency laws. These laws may be less developed and more cumbersome with respect to the Fund’s non-U.S. floating rate investments. Floating rate loans may not be fully collateralized or may be uncollateralized. Uncollateralized loans involve a greater risk of loss. In the event of a default, the Fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. In addition, the lender’s security interest or their enforcement of their security interest under the loan agreement may be found by a court to be invalid or the collateral may be used to pay other outstanding obligations of the borrower. Further, the Fund’s access to collateral, if any, may be limited by bankruptcy law. To the extent that a loan is collateralized by stock of the borrower or its affiliates, this stock may lose all or substantially all of its value in the event of bankruptcy of the borrower. Loans that are obligations of a holding company are subject to the risk that, in a bankruptcy of a subsidiary operating company, creditors of the subsidiary may recover from the subsidiary’s assets before the lenders to the holding company would receive any amount on account of the holding company’s interest in the subsidiary. Risk of disadvantaged access to confidential information. The issuer of a floating rate loan may offer to provide material, non-public information about the issuer to investors, such as the Fund. Normally, the Adviser will seek to avoid receiving this type of information about the issuer of a loan either held by, or considered for investment by, the Fund. the Adviser’s decision not to receive the information may place it at a disadvantage, relative to other loan investors, in assessing a loan or the loan’s issuer. For example, in instances where holders of floating rate loans are asked to grant amendments, waivers or consents, the Adviser’s inability to assess the impact of these actions may adversely affect the value of the portfolio. For this and other reasons, it is possible that the Adviser’s decision not to receive material, non-public information under normal circumstances could adversely affect the Fund’s investment performance. Risks of subordinated securities . A holder of securities that are subordinated or “junior” to more senior securities of an issuer is entitled to payment after holders of more senior securities of the issuer. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer, any loss incurred by the subordinated securities is likely to be proportionately greater, and any recovery of interest or principal may take more time. If there is a default, bankruptcy or liquidation of the issuer, most subordinated securities are paid only if sufficient assets remain after payment of the issuer’s non-subordinated securities. As a result, even a perceived decline in creditworthiness of the issuer is likely to have a greater impact on subordinated securities than more senior securities. Issuer risk. The value of corporate income-producing securities may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services. U.S. Treasury obligations risk. The market value of direct obligations of the U.S. Treasury may vary due to changes in interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s investments in obligations issued by the U.S. Treasury to decline. U.S. government agency obligations risk. The Fund invests in obligations issued by agencies and instrumentalities of the U.S. government. Government-sponsored entities such as Federal National Mortgage Association (FNMA), the Federal Home Loan Mortgage Corporation (FHLMC) and the Federal Home Loan Banks (FHLBs), although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt and mortgage-backed securities issued by them are neither guaranteed nor issued by the U.S. government. The maximum potential liability of the issuers of some U.S. government obligations may greatly exceed their current resources, including any legal right to support from the U.S. government. Such debt and mortgage-backed securities are subject to the risk of default on the payment of interest and/or principal, similar to debt of private issuers. Although the U.S. government has provided financial support to FNMA and FHLMC in the past, there can be no assurance that it will support these or other government-sponsored entities in the future. Mortgage-related and asset-backed securities risk . The value of mortgage-related securities, including commercial mortgage-backed securities, collateralized mortgage-backed securities, credit risk transfer securities, and asset-backed securities, will be influenced by factors affecting the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities tend to be more sensitive to changes in interest rates than other types of debt securities. These securities are also subject to interest rate, prepayment and extension risks. Some of these securities may receive little or no collateral protection from the underlying assets and are thus subject to the risk of default. The risk of such defaults is generally higher in the case of mortgage-backed investments offered by non-governmental issuers and those that include so-called “sub-prime” mortgages. The structure of some of these securities may be complex and there may be less available information than for other types of debt securities. Upon the occurrence of certain triggering events or defaults, the Fund may become the holder of underlying assets at a time when those assets may be difficult to sell or may be sold only at a loss. Risks of investing in collateralized debt obligations. Investment in a collateralized debt obligation (CDO) is subject to the credit, subordination, interest rate, valuation, prepayment, extension and other risks of the obligations underlying the CDO and the tranche of the CDO in which the Fund invests. CDOs are subject to liquidity risk. Synthetic CDOs are also subject to the risks of investing in derivatives, such as credit default swaps, and leverage risk. Risks of instruments that allow for balloon payments or negative amortization payments. Certain debt instruments allow for balloon payments or negative amortization payments. Such instruments permit the borrower to avoid paying currently a portion of the interest accruing on the instrument. While these features make the debt instrument more affordable to the borrower in the near term, they increase the risk that the borrower will be unable to make the resulting higher payment or payments that become due at the maturity of the loan. Risks of investing in insurance-linked securities. The Fund could lose a portion or all of the principal it has invested in an insurance-linked security, and the right to additional interest and/or dividend payments with respect to the security, upon the occurrence of one or more trigger events, as defined within the terms of an insurance-linked security. Trigger events may include natural or other perils of a specific size or magnitude that occur in a designated geographic region during a specified time period, and/or that involve losses or other metrics that exceed a specific amount. Natural perils include disasters such as hurricanes, earthquakes, windstorms, fires, floods and other weather-related occurrences, as well as mortality or longevity events. Non-natural perils include disasters resulting from human-related activity such as commercial and industrial accidents or business interruptions. Major natural disasters (such as in the cases of Super Typhoon Goni in the Philippines in 2020, monsoon flooding in China in 2020, Hurricane Irma in Florida and the Caribbean in 2017, Super Storm Sandy in 2012, and Hurricane Ian in Florida in 2022) or commercial and industrial accidents (such as aviation disasters and oil spills) can result in significant losses, and investors in ILS with exposure to such natural or other disasters may also experience substantial losses. If the likelihood and severity of natural and other large disasters increase, the risk of significant losses to reinsurers may increase. Typically, one significant triggering event (even in a major metropolitan area) will not result in financial failure to a reinsurer. However, a series of major triggering events could cause the failure of a reinsurer. Similarly, to the extent the Fund invests in ILS for which a triggering event occurs, losses associated with such event will result in losses to the Fund and a series of major triggering events affecting a large portion of the ILS held by the Fund will result in substantial losses to the Fund. The Fund may also invest in insurance-linked securities that are subject to "indemnity triggers." An indemnity trigger is a trigger based on the actual losses of the ceding sponsor (i.e., the party seeking reinsurance). Insurance-linked securities subject to indemnity triggers are often regarded as being subject to potential moral hazard, since such insurance-linked securities are triggered by actual losses of the ceding sponsor and the ceding sponsor may have an incentive to take actions and/or risks that would have an adverse effect on the Fund. For example, a ceding sponsor might inflate its total claims paid above the ILS trigger level in order to share its losses with investors in the ILS. Thus, bonds with indemnity triggers may be subject to moral hazard, because the trigger depends on the ceding sponsor to properly identify and calculate losses that do and do not apply in determining whether the trigger amount has been reached. In short, “moral hazard” refers to this potential for the sponsor to influence bond performance, as payouts are based on the individual policy claims against the sponsor and the way the sponsor settles those claims. There is no way to accurately predict whether a trigger event will occur and, accordingly, event-linked bonds and other insurance-linked securities carry significant risk. In addition to the specified trigger events, insurance-linked securities may expose the Fund to other risks, including but not limited to issuer (credit) default, adverse regulatory or jurisdictional interpretations and adverse tax consequences. Insurance-linked securities are also subject to the risk that the model used to calculate the probability of a trigger event was not accurate and underestimated the likelihood of a trigger event. Insurance-linked securities may provide for extensions of maturity in order to process and audit loss claims in those cases when a trigger event has, or possibly has, occurred. Certain insurance-linked securities may have limited liquidity, or may be illiquid. Upon the occurrence or possible occurrence of a trigger event, and until the completion of the processing and auditing of applicable loss claims, the Fund’s investment in an insurance-linked security may be priced using fair value methods. Lack of a liquid market may impose the risk of higher transaction costs and the possibility that the Fund may be forced to liquidate positions when it would not be advantageous to do so. Certain insurance-linked securities represent interests in baskets of underlying reinsurance contracts. The Fund has limited transparency into the individual contracts underlying certain insurance-linked securities, and therefore must rely on the risk assessment and sound underwriting practices of the insurer and/or reinsurer. Certain insurance-linked securities may be difficult to value. Risks of zero coupon bonds, payment in kind, deferred and contingent payment securities. These securities may be more speculative and may fluctuate more i
Effects of Leverage [Text Block]		Effects of Leverage The following table is furnished in response to requirements of the Securities and Exchange Commission. It is designed to illustrate the effects of leverage on common share total return, assuming investment portfolio total returns (consisting of income and changes in the value of investments held in the Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. The table below reflects the Fund’s borrowings under a credit agreement as of November 30, 2023 as a percentage of the Fund’s total assets (which includes assets attributable to such leverage), the annual rate of interest on the borrowings as of November 30, 2023, and the annual return that the Fund’s portfolio must experience (net of expenses) in order to cover such costs. The information below does not reflect the Fund’s use of certain other forms of economic leverage achieved through the use of other instruments or transactions not considered to be senior securities under the 1940 Act, if any. The assumed investment portfolio returns in the table below are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. Your actual returns may be greater or less than those appearing below. In addition, actual expenses associated with borrowings by the Fund may vary frequently and may be significantly higher or lower than the rate used for the example below. Borrowings under credit agreement as a percentage of total managed assets (including assets attributable to borrowings) 32.88% Annual effective interest rate payable by Fund on borrowings 5.97% Annual return Fund portfolio must experience (net of expenses) to cover interest rate on borrowings 1.96% Common share total return for (10.00)% assumed portfolio total return (17.82)% Common share total return for (5.00)% assumed portfolio total return (10.37)% Common share total return for 0.00% assumed portfolio total return (2.92)% Common share total return for 5.00% assumed portfolio total return 4.52% Common share total return for 10.00% assumed portfolio total return 11.97% Common share total return is composed of two elements - investment income net of the Fund’s expenses, including any interest/dividends on assets resulting from leverage, and gains or losses on the value of the securities the Fund owns. As required by Securities and Exchange Commission rules, the table assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0%, the Fund must assume that the income it receives on its investments is entirely offset by losses in the value of those investments. This table reflects hypothetical performance of the Fund’s portfolio and not the performance of the Fund’s common shares, the value of which will be determined by market forces and other factors. Should the Fund elect to add additional leverage to its portfolio, the potential benefits of leveraging the Fund’s shares cannot be fully achieved until the proceeds resulting from the use of leverage have been received by the Fund and invested in accordance with the Fund’s investment objective and principal investment strategies. The Fund’s willingness to use additional leverage, and the extent to which leverage is used at any time, will depend on many factors, including, among other things, the Adviser’s assessment of the yield curve environment, interest rate trends, market conditions and other factors.

General [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		General. The Fund is a closed-end management investment company designed primarily as a long-term investment and not as a trading tool. The Fund is not a complete investment program and should be considered only as an addition to an investor’s existing portfolio of investments. Because the Fund may invest substantially in high yield debt securities, an investment in the Fund’s shares is speculative in that it involves a high degree of risk. Due to uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objective. Instruments in which the Fund invests may only have limited liquidity, or may be illiquid.
Market price of shares [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Market price of shares . Common shares of closed-end funds frequently trade at a price lower than their net asset value. This is commonly referred to as “trading at a discount.” This characteristic of shares of closed-end funds is a risk separate and distinct from the risk that the Fund’s net asset value may decrease. Both long and short-term investors, including investors who sell their shares within a relatively short period after purchase, will be exposed to this risk. The Fund is designed primarily for long-term investors and should not be considered a vehicle for trading purposes. Whether investors will realize a gain or loss upon the sale of the Fund’s Common Shares will depend upon whether the market value of the shares at the time of sale is above or below the price the investor paid, taking into account transaction costs, for the shares and is not directly dependent upon the Fund’s net asset value. Because the market value of the Fund’s shares will be determined by factors such as the relative demand for and supply of the shares in the market, general market conditions and other factors beyond the control of the Fund, the Fund cannot predict whether its Common Shares will trade at, below or above net asset value, or below or above the offering price for the shares.
Market risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Market risk. The market prices of securities or other assets held by the Fund may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political, or regulatory conditions, political instability, recessions, inflation, changes in interest or currency rates, lack of liquidity in the bond markets, the spread of infectious illness or other public health issues, weather or climate crisis, armed conflict, market disruptions caused by tariffs, trade disputes, sanctions or other government actions, or other factors or adverse investor sentiment. If the market prices of the Fund’s securities and assets fall, the value of your investment will go down. A change in financial condition or other event affecting a single issuer or market may adversely impact securities markets as a whole. Changes in market conditions may not have the same impact on all types of securities. The value of securities may also fall due to specific conditions that affect a particular sector of the securities market or a particular issuer. In the past decade, financial markets throughout the world have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. Governmental and non-governmental issuers have defaulted on, or been forced to restructure, their debts. These conditions may continue, recur, worsen or spread. Events that have contributed to these market conditions include, but are not limited to, major cybersecurity events; geopolitical events (including wars, terror attacks and economic sanctions); measures to address budget deficits; downgrading of sovereign debt; changes in oil and commodity prices; dramatic changes in currency exchange rates; global pandemics; and public sentiment. The long-term impact of the COVID-19 pandemic and its subsequent variants on economies, markets, industries and individual issuers, are not known. Some sectors of the economy and individual issuers have experienced or may experience particularly large losses. Periods of extreme volatility in the financial markets, reduced liquidity of many instruments, increased government debt, inflation, and disruptions to supply chains, consumer demand and employee availability, may continue for some time. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. Inflation and interest rates have increased and may rise further. These circumstances could adversely affect the value and liquidity of the Fund’s investments and negatively impact the Fund’s performance. In addition, inflation, rising interest rates, global supply chain disruptions and other market events could adversely affect the companies or issuers in which the Fund invests. Following Russia’s invasion of Ukraine, Russian securities lost all, or nearly all, their market value. Other securities or markets could be similarly affected by past or future political, geopolitical or other events or conditions. Governments and central banks, including the U.S. Federal Reserve, have taken extraordinary and unprecedented actions to support local and global economies and the financial markets. These actions have resulted in significant expansion of public debt, including in the U.S. The consequences of high public debt, including its future impact on the economy and securities markets, may not be known for some time. U.S. Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including increases or decreases in interest rates, or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation, and these and other events affecting global markets, such as the United Kingdom’s exit from the European Union (or Brexit), potential trade imbalances with China or other countries, or sanctions or other government actions against Russia, other nations or individuals or companies (or their countermeasures), may contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes on the markets, and the implications for market participants, may not be fully known for some time. The U.S. and other countries are periodically involved in disputes over trade and other matters, which may result in tariffs, investment restrictions and adverse impacts on affected companies and securities. For example, the U.S. has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the U.S. and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The U.S. government has prohibited U.S. persons, such as the Fund, from investing in Chinese companies designated as related to the Chinese military. These and possible future restrictions could limit the Fund’s opportunities for investment and require the sale of securities at a loss or make them illiquid. Moreover, the Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the U.S. and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the Fund’s assets may go down. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, armed conflict such as between Russia and Ukraine or in the Middle East, terrorism, natural disasters, infectious illness or public health issues, cybersecurity events, supply chain disruptions, sanctions against Russia, other nations or individuals or companies and possible countermeasures, and other circumstances in one country or region could have profound impacts on other countries or regions and 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. The Fund may experience a substantial or complete loss on any individual security or derivative position. Until recently, a commonly used reference rate for floating rate securities was LIBOR (London Interbank Offered Rate). ICE Benchmark Administration, the administrator of LIBOR, has ceased publication of most LIBOR settings on a representative basis. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in most major currencies. In the U.S., a common benchmark replacement is based on the Secured Overnight Financing Rate (SOFR) published by the Federal Reserve Bank of New York, including certain spread adjustments and benchmark replacement conforming changes, although other benchmark replacements (with or without spread adjustments) may be used in certain transactions. The impact of the transition from LIBOR on the Fund’s transactions and financial markets generally cannot yet be determined. The transition away from LIBOR may lead to increased volatility and illiquidity in markets for instruments that have relied on LIBOR and may adversely affect the Fund’s performance.
High yield or junk bond risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		High yield or “junk” bond risk . Debt securities that are below investment grade, called “junk bonds,” are speculative, have a higher risk of default or are already in default, tend to be less liquid and are more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments. These risks are more pronounced for securities that are already in default.
Interests Rate Risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Interest rate risk. The market prices of the Fund’s fixed income securities may fluctuate significantly when interest rates change. The value of your investment will generally go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term or duration securities. For example, if interest rates increase by 1%, the value of a Fund’s portfolio with a portfolio duration of ten years would be expected to decrease by 10%, all other things being equal. In recent years interest rates and credit spreads in the U.S. have been at historic lows. The U.S. Federal Reserve has raised certain interest rates, and interest rates may continue to go up. A general rise in interest rates could adversely affect the price and liquidity of fixed income securities. The maturity of a security may be significantly longer than its effective duration. A security’s maturity and other features may be more relevant than its effective duration in determining the security’s sensitivity to other factors affecting the issuer or markets generally, such as changes in credit quality or in the yield premium that the market may establish for certain types of securities (sometimes called “credit spread”). In general, the longer its maturity the more a security may be susceptible to these factors. When the credit spread for a fixed income security goes up, or “widens,” the value of the security will generally go down. Rising interest rates can lead to increased default rates, as issuers of floating rate securities find themselves faced with higher payments. Unlike fixed rate securities, floating rate securities generally will not increase in value if interest rates decline. Changes in interest rates also will affect the amount of interest income the Fund earns on its floating rate investments.
Credits risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Credit risk. If an issuer or guarantor of a security held by the Fund or a counterparty to a financial contract with the Fund defaults on its obligation to pay principal and/or interest, has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines, the value of your investment will typically decline. Changes in actual or perceived creditworthiness may occur quickly. The Fund could be delayed or hindered in its enforcement of rights against an issuer, guarantor or counterparty.
Prepayment or call risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Prepayment or call risk. Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the Fund will not benefit from the rise in market price that normally accompanies a decline in interest rates, and will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The Fund also may lose any premium it paid on the security.
Extension risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Extension risk. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected principal payments. This may lock in a below market interest rate, increase the security’s duration and reduce the value of the security.
Risk of illiquid investments [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risk of illiquid investments. Certain securities and derivatives held by the Fund may be impossible or difficult to purchase, sell or unwind. Illiquid securities and derivatives also may be difficult to value. Liquidity risk may be magnified in an environment of rising interest rates or widening credit spreads. During times of market turmoil, there have been, and may be, no buyers or sellers for securities in entire asset classes. If the Fund is forced to sell an illiquid asset or unwind a derivatives position, the Fund may suffer a substantial loss or may not be able to sell at all.
Portfolio selection risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Portfolio selection risk. The Adviser’s judgment about the quality, relative yield, relative value or market trends affecting a particular sector or region, market segment, security, industry or about interest rates or other market factors may prove to be incorrect or may not produce the desired results, or there may be imperfections, errors or limitations in the models, tools and information used by the Adviser.
Reinvestment risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Reinvestment risk. Income from the Fund’s portfolio will decline if the Fund invests the proceeds, repayment or sale of loans or other obligations into lower yielding instruments with a lower spread over the base lending rate. A decline in income could affect the common shares’ distribution rate and their overall return.
Risks of investing in floating rate loans [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risks of investing in floating rate loans. Floating rate loans and similar investments may be illiquid or less liquid than other investments and difficult to value. Market quotations for these securities may be volatile and/or subject to large spreads between bid and ask prices. No active trading market may exist for many floating rate loans, and many loans are subject to restrictions on resale. Any secondary market may be subject to irregular trading activity and extended trade settlement periods. An economic downturn generally leads to a higher non-payment rate, and a loan may lose significant value before a default occurs. When the Fund invests in a loan participation, the Fund does not have a direct claim against the borrower and must rely upon an intermediate participant to enforce any rights against the borrower. As a result, the Fund is subject to the risk that an intermediate participant between the Fund and the borrower will fail to meet its obligations to the Fund, in addition to the risk that the issuer of the loan will default on its obligations. Also, the Fund may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Fund to the creditworthiness of the lender as well as the borrower. There is less readily available, reliable information about most senior loans than is the case for many other types of securities. Although the features of senior loans, including being secured by collateral and having priority over other obligations of the issuer, reduce some of the risks of investment in below investment grade securities, the loans are subject to significant risks. the Adviser believes, based on its experience, that senior floating rate loans generally have more favorable loss recovery rates than most other types of below investment grade obligations. However, there can be no assurance that the Fund’s actual loss recovery experience will be consistent with the Adviser’s prior experience or that the senior loans in which the Fund invests will achieve any specific loss recovery rate. The types of covenants included in loan agreements generally vary depending on market conditions, the creditworthiness of the issuer, the nature of the collateral securing the loan, and other factors. Loans may have restrictive covenants that limit the ability of a borrower to further encumber its assets. If a borrower fails to comply with the covenants included in a loan agreement, the borrower may default in payment of the loan. Some of the loans in which the Fund may invest may be “covenant lite.” Covenant lite loans contain fewer maintenance covenants, or no maintenance covenants at all, than traditional loans and may not include terms that allow the lender to monitor the financial performance of the borrower and declare a default if certain criteria are breached. This may expose the Fund to greater credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result the Fund’s exposure to losses on such investments may be increased, especially during a downturn in the credit cycle. Second lien loans generally are subject to similar risks as those associated with senior loans. Because second lien loans are subordinated or unsecured and thus lower in priority on 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. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Second lien loans generally have greater price volatility than senior loans and may be less liquid. Certain floating rate loans and other corporate debt securities involve refinancings, recapitalizations, mergers and acquisitions, and other financings for general corporate purposes. Other loans are incurred in restructuring or “work-out” scenarios, including debtor-in-possession facilities in bankruptcy. Loans in restructuring or similar scenarios may be especially vulnerable to the inherent uncertainties in restructuring processes. In addition, the highly leveraged capital structure of the borrowers in any of these transactions, whether acquisition financing or restructuring, may make the loans especially vulnerable to adverse economic or market conditions and the risk of default. Loans to entities located outside of the U.S. may have substantially different lender protections and covenants as compared to loans to U.S. entities and may involve greater risks. The Fund may have difficulties and incur expense enforcing its rights with respect to non-U.S. loans and such loans could be subject to bankruptcy laws that are materially different than in the U.S. Because affiliates of the Adviser may participate in the primary and secondary market for senior loans, limitations under applicable law may restrict the Fund’s ability to participate in a restructuring of a senior loan or to acquire some senior loans, or affect the timing or price of such acquisition. Loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections afforded by federal securities laws.
Collateral risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Collateral risk. The value of collateral, if any, securing a floating rate loan can decline, and may be insufficient to meet the issuer’s obligations or may be difficult to liquidate. In addition, the Fund’s access to collateral may be limited by bankruptcy or other insolvency laws. These laws may be less developed and more cumbersome with respect to the Fund’s non-U.S. floating rate investments. Floating rate loans may not be fully collateralized or may be uncollateralized. Uncollateralized loans involve a greater risk of loss. In the event of a default, the Fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. In addition, the lender’s security interest or their enforcement of their security interest under the loan agreement may be found by a court to be invalid or the collateral may be used to pay other outstanding obligations of the borrower. Further, the Fund’s access to collateral, if any, may be limited by bankruptcy law. To the extent that a loan is collateralized by stock of the borrower or its affiliates, this stock may lose all or substantially all of its value in the event of bankruptcy of the borrower. Loans that are obligations of a holding company are subject to the risk that, in a bankruptcy of a subsidiary operating company, creditors of the subsidiary may recover from the subsidiary’s assets before the lenders to the holding company would receive any amount on account of the holding company’s interest in the subsidiary.
Risk of disadvantaged access to confidential information [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risk of disadvantaged access to confidential information. The issuer of a floating rate loan may offer to provide material, non-public information about the issuer to investors, such as the Fund. Normally, the Adviser will seek to avoid receiving this type of information about the issuer of a loan either held by, or considered for investment by, the Fund. the Adviser’s decision not to receive the information may place it at a disadvantage, relative to other loan investors, in assessing a loan or the loan’s issuer. For example, in instances where holders of floating rate loans are asked to grant amendments, waivers or consents, the Adviser’s inability to assess the impact of these actions may adversely affect the value of the portfolio. For this and other reasons, it is possible that the Adviser’s decision not to receive material, non-public information under normal circumstances could adversely affect the Fund’s investment performance.
Risks of subordinated securities [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risks of subordinated securities . A holder of securities that are subordinated or “junior” to more senior securities of an issuer is entitled to payment after holders of more senior securities of the issuer. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer, any loss incurred by the subordinated securities is likely to be proportionately greater, and any recovery of interest or principal may take more time. If there is a default, bankruptcy or liquidation of the issuer, most subordinated securities are paid only if sufficient assets remain after payment of the issuer’s non-subordinated securities. As a result, even a perceived decline in creditworthiness of the issuer is likely to have a greater impact on subordinated securities than more senior securities.
Issuer risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Issuer risk. The value of corporate income-producing securities may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.
U.S. Treasury obligations risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		U.S. Treasury obligations risk. The market value of direct obligations of the U.S. Treasury may vary due to changes in interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s investments in obligations issued by the U.S. Treasury to decline.
U.S. government agency obligations risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		U.S. government agency obligations risk. The Fund invests in obligations issued by agencies and instrumentalities of the U.S. government. Government-sponsored entities such as Federal National Mortgage Association (FNMA), the Federal Home Loan Mortgage Corporation (FHLMC) and the Federal Home Loan Banks (FHLBs), although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt and mortgage-backed securities issued by them are neither guaranteed nor issued by the U.S. government. The maximum potential liability of the issuers of some U.S. government obligations may greatly exceed their current resources, including any legal right to support from the U.S. government. Such debt and mortgage-backed securities are subject to the risk of default on the payment of interest and/or principal, similar to debt of private issuers. Although the U.S. government has provided financial support to FNMA and FHLMC in the past, there can be no assurance that it will support these or other government-sponsored entities in the future.
Mortgagerelated and assetbacked securities risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Mortgage-related and asset-backed securities risk . The value of mortgage-related securities, including commercial mortgage-backed securities, collateralized mortgage-backed securities, credit risk transfer securities, and asset-backed securities, will be influenced by factors affecting the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities tend to be more sensitive to changes in interest rates than other types of debt securities. These securities are also subject to interest rate, prepayment and extension risks. Some of these securities may receive little or no collateral protection from the underlying assets and are thus subject to the risk of default. The risk of such defaults is generally higher in the case of mortgage-backed investments offered by non-governmental issuers and those that include so-called “sub-prime” mortgages. The structure of some of these securities may be complex and there may be less available information than for other types of debt securities. Upon the occurrence of certain triggering events or defaults, the Fund may become the holder of underlying assets at a time when those assets may be difficult to sell or may be sold only at a loss.
Risks of investing in collateralized debt obligations [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risks of investing in collateralized debt obligations. Investment in a collateralized debt obligation (CDO) is subject to the credit, subordination, interest rate, valuation, prepayment, extension and other risks of the obligations underlying the CDO and the tranche of the CDO in which the Fund invests. CDOs are subject to liquidity risk. Synthetic CDOs are also subject to the risks of investing in derivatives, such as credit default swaps, and leverage risk.
Risks of instruments that allow for balloon payments or negative amortization payments [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risks of instruments that allow for balloon payments or negative amortization payments. Certain debt instruments allow for balloon payments or negative amortization payments. Such instruments permit the borrower to avoid paying currently a portion of the interest accruing on the instrument. While these features make the debt instrument more affordable to the borrower in the near term, they increase the risk that the borrower will be unable to make the resulting higher payment or payments that become due at the maturity of the loan.
Risks of Investing in Insurance Linked Securities [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risks of investing in insurance-linked securities. The Fund could lose a portion or all of the principal it has invested in an insurance-linked security, and the right to additional interest and/or dividend payments with respect to the security, upon the occurrence of one or more trigger events, as defined within the terms of an insurance-linked security. Trigger events may include natural or other perils of a specific size or magnitude that occur in a designated geographic region during a specified time period, and/or that involve losses or other metrics that exceed a specific amount. Natural perils include disasters such as hurricanes, earthquakes, windstorms, fires, floods and other weather-related occurrences, as well as mortality or longevity events. Non-natural perils include disasters resulting from human-related activity such as commercial and industrial accidents or business interruptions. Major natural disasters (such as in the cases of Super Typhoon Goni in the Philippines in 2020, monsoon flooding in China in 2020, Hurricane Irma in Florida and the Caribbean in 2017, Super Storm Sandy in 2012, and Hurricane Ian in Florida in 2022) or commercial and industrial accidents (such as aviation disasters and oil spills) can result in significant losses, and investors in ILS with exposure to such natural or other disasters may also experience substantial losses. If the likelihood and severity of natural and other large disasters increase, the risk of significant losses to reinsurers may increase. Typically, one significant triggering event (even in a major metropolitan area) will not result in financial failure to a reinsurer. However, a series of major triggering events could cause the failure of a reinsurer. Similarly, to the extent the Fund invests in ILS for which a triggering event occurs, losses associated with such event will result in losses to the Fund and a series of major triggering events affecting a large portion of the ILS held by the Fund will result in substantial losses to the Fund. The Fund may also invest in insurance-linked securities that are subject to "indemnity triggers." An indemnity trigger is a trigger based on the actual losses of the ceding sponsor (i.e., the party seeking reinsurance). Insurance-linked securities subject to indemnity triggers are often regarded as being subject to potential moral hazard, since such insurance-linked securities are triggered by actual losses of the ceding sponsor and the ceding sponsor may have an incentive to take actions and/or risks that would have an adverse effect on the Fund. For example, a ceding sponsor might inflate its total claims paid above the ILS trigger level in order to share its losses with investors in the ILS. Thus, bonds with indemnity triggers may be subject to moral hazard, because the trigger depends on the ceding sponsor to properly identify and calculate losses that do and do not apply in determining whether the trigger amount has been reached. In short, “moral hazard” refers to this potential for the sponsor to influence bond performance, as payouts are based on the individual policy claims against the sponsor and the way the sponsor settles those claims. There is no way to accurately predict whether a trigger event will occur and, accordingly, event-linked bonds and other insurance-linked securities carry significant risk. In addition to the specified trigger events, insurance-linked securities may expose the Fund to other risks, including but not limited to issuer (credit) default, adverse regulatory or jurisdictional interpretations and adverse tax consequences. Insurance-linked securities are also subject to the risk that the model used to calculate the probability of a trigger event was not accurate and underestimated the likelihood of a trigger event. Insurance-linked securities may provide for extensions of maturity in order to process and audit loss claims in those cases when a trigger event has, or possibly has, occurred. Certain insurance-linked securities may have limited liquidity, or may be illiquid. Upon the occurrence or possible occurrence of a trigger event, and until the completion of the processing and auditing of applicable loss claims, the Fund’s investment in an insurance-linked security may be priced using fair value methods. Lack of a liquid market may impose the risk of higher transaction costs and the possibility that the Fund may be forced to liquidate positions when it would not be advantageous to do so. Certain insurance-linked securities represent interests in baskets of underlying reinsurance contracts. The Fund has limited transparency into the individual contracts underlying certain insurance-linked securities, and therefore must rely on the risk assessment and sound underwriting practices of the insurer and/or reinsurer. Certain insurance-linked securities may be difficult to value.
Risks of zero coupon bonds, payment in kind, deferred and contingent payment securities [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risks of zero coupon bonds, payment in kind, deferred and contingent payment securities. These securities may be more speculative and may fluctuate more in value than securities which pay income periodically and in cash. In addition, although the Fund receives no periodic cash payments on such securities, the Fund is deemed for tax purposes to receive income from such securities, which applicable tax rules require the Fund to distribute to stockholders. Such distributions may be taxable when distributed to stockholders.
Risks Of Non U S Investments [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risks of non-U.S. investments. Investing in non-U.S. issuers, or in U.S. issuers that have significant exposure to foreign markets, may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced for issuers in emerging markets or to the extent that the Fund invests significantly in one region or country. These risks may include different financial reporting practices and regulatory standards, less liquid trading markets, extreme price volatility, currency risks, changes in economic, political, regulatory and social conditions, military conflicts and sanctions, terrorism, sustained economic downturns, financial instability, reduction of government or central bank support, inadequate accounting standards, tariffs, tax disputes or other tax burdens, nationalization or expropriation of assets, arbitrary application of laws and regulations or lack of rule of law, and investment and repatriation restrictions. Lack of information and less market regulation also may affect the value of these securities. Withholding and other non-U.S. taxes may decrease the Fund’s return. Non-U.S. issuers may be located in parts of the world that have historically been prone to natural disasters. Emerging market economies tend to be less diversified than those of more developed countries. They typically have fewer medical and economic resources than more developed countries and thus they may be less able to control or mitigate the effects of a pandemic. Investing in depositary receipts is subject to many of the same risks as investing directly in non-U.S. issuers. Depositary receipts may involve higher expenses and may trade at a discount (or premium) to the underlying security. A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. In addition, the United Kingdom has withdrawn from the EU (commonly known as “Brexit”). Other countries may seek to withdraw from the EU and/or abandon the euro, the common currency of the EU. The range and potential implications of possible political, regulatory, economic, and market outcomes of Brexit cannot be fully known but could be significant, potentially resulting in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which will adversely affect the Fund’s investments. If one or more stockholders of a supranational entity such as the World Bank fail to make necessary additional capital contributions, the entity may be unable to pay interest or repay principal on its debt securities. Sanctions or other government actions against certain countries could negatively impact the Fund’s investments in securities that have exposure to that country. Circumstances that impact one country could have profound impacts on other countries and on global economies or markets. China and other developing market countries may be subject to considerable degrees of economic, political and social instability. The U.S. government has imposed restrictions on U.S. investor participation in certain Chinese investments. These matters could adversely affect China’s economy. In addition, China’s long-running conflict over Taiwan’s sovereignty, border disputes with many neighbors and historically strained relations with other Asian countries could result in military conflict that could adversely impact the economies of China and other Asian countries, disrupt supply chains, and severely affect global economies and markets. Russia launched a large-scale invasion of Ukraine on February 24, 2022. In response to the military action by Russia, various countries, including the U.S., the United Kingdom, and European Union issued broad-ranging economic sanctions against Russia and Belarus and certain companies and individuals. Russia has taken retaliatory actions, including preventing repatriation of capital by U.S. and other investors. Since then, Russian securities have lost all, or nearly all, their market value, and many other issuers, securities and markets have been adversely affected. The ongoing conflict has resulted in significant market disruptions, including in certain markets, industries and sectors, such as the oil and natural gas markets, and negatively affected global supply chains, food supplies, inflation and global growth. The United States and other countries may impose sanctions on other countries, companies and individuals in light of Russia’s military invasion. The extent and duration of the military action or future escalation of such hostilities, the extent and impact of existing and future sanctions, market disruptions and volatility, and the result of any diplomatic negotiations cannot be predicted. These and any related events could have a significant impact on the value and liquidity of certain Fund investments, on Fund performance and the value of an investment in the Fund.
Currency risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Currency risk. The Fund could experience losses based on changes in the exchange rate between non-U.S. currencies and the U.S. dollar or as a result of currency conversion costs. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls and speculation.
Risks of convertible securities [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risks of convertible securities. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. A downturn in equity markets may cause the price of convertible securities to decrease relative to other fixed income securities.
Preferred stocks risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Preferred stocks risk. Preferred stocks may pay fixed or adjustable rates of return. Preferred stocks are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company’s preferred stocks generally pay dividends only after the company makes required payments to holders of its bonds and other debt. Thus, the value of preferred stocks will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. The market value of preferred stocks generally decreases when interest rates rise. Also, the market prices of preferred stocks are more sensitive to changes in the issuer’s creditworthiness than are the prices of debt securities. Generally, under normal circumstances, preferred stocks do not carry voting rights. Preferred stocks may trade less frequently and in a more limited volume and may be subject to more abrupt or erratic price movements than other securities. Preferred stocks of smaller companies may be more vulnerable to adverse developments than preferred stocks of larger companies.
Risks of investment in other funds [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Risks of investment in other funds. Investing in other investment companies, including exchange-traded funds (ETFs) and closed-end funds, subjects the Fund to the risks of investing in the underlying securities or assets held by those funds. When investing in another fund, the Fund will bear a pro rata portion of the underlying fund’s expenses, including management fees, in addition to its own expenses. ETFs and closed-end funds are bought and sold based on market prices and can trade at a premium or a discount to the ETF’s or closed-end fund’s net asset value. Such funds may trade at a discount for an extended period and may not ever realize their net asset value.
Derivatives risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Derivatives risk. Using swaps, forward foreign currency exchange contracts, bond and interest rate futures and other derivatives can increase Fund losses and reduce opportunities for gains when market prices, interest rates or the derivative instruments themselves behave in a way not anticipated by the Fund. Using derivatives may increase the volatility of the Fund’s net asset value and may not provide the result intended. Derivatives may have a leveraging effect on the Fund. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. Derivatives are generally subject to the risks applicable to the assets, rates, indices or other indicators underlying the derivative. Changes in a derivative’s value may not correlate well with the referenced asset or metric. The Fund also may have to sell assets at inopportune times to satisfy its obligations. Derivatives may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the Fund. Use of derivatives may have different tax consequences for the Fund than an investment in the underlying security, and such differences may affect the amount, timing and character of income distributed to stockholders. The U.S. government and foreign governments have adopted and implemented or are in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make them more costly, limit their availability or utility, otherwise adversely affect their performance or disrupt markets.
Credit default swap risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Credit default swap risk . Credit default swap contracts, a type of derivative instrument, involve special risks and may result in losses to the Fund. Credit default swaps may in some cases be illiquid, and they increase credit risk since the Fund has exposure to the issuer of the referenced obligation and either the counterparty to the credit default swap or, if it is a cleared transaction, the brokerage firm through which the trade was cleared and the clearing organization that is the counterparty to that trade.
Structured Securities Risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Structured securities risk. Structured securities may behave in ways not anticipated by the Fund, or they may not receive the tax, accounting or regulatory treatment anticipated by the Fund.
Forward foreign currency transactions risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Forward foreign currency transactions risk. The Fund may not fully benefit from or may lose money on forward foreign currency transactions if changes in currency rates do not occur as anticipated or do not correspond accurately to changes in the value of the Fund’s holdings, or if the counterparty defaults. Such transactions may also prevent the Fund from realizing profits on favorable movements in exchange rates. Risk of counterparty default is greater for counterparties located in emerging markets.
Leveraging risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Leveraging risk. The value of your investment may be more volatile and other risks tend to be compounded if the Fund borrows or uses derivatives or other investments, such as ETFs, that have embedded leverage. Leverage generally magnifies the effect of any increase or decrease in the value of the Fund’s underlying assets and creates a risk of loss of value on a larger pool of assets than the Fund would otherwise have, potentially resulting in the loss of all assets. Engaging in such transactions may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations. New derivatives regulations require the Fund, to the extent it uses derivatives to a material extent, to, among other things, comply with certain overall limits on leverage. These regulations may limit the ability of the Fund to pursue its investment strategies and may not be effective to mitigate the Fund’s risk of loss from derivatives. The Fund may use financial leverage on an ongoing basis for investment purposes by borrowing from banks through a revolving credit facility. The fees and expenses attributed to leverage, including any increase in the management fees, will be borne by holders of common shares. Since the Adviser’s fee is based on a percentage of the Fund’s managed assets, its fee will be higher if the Fund is leveraged, and the Adviser will thus have an incentive to leverage the Fund.
Repurchase agreement risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Repurchase agreement risk. In the event that the other party to a repurchase agreement defaults on its obligations, the Fund may encounter delay and incur costs before being able to sell the security. Such a delay may involve loss of interest or a decline in price of the security. In addition, if the Fund is characterized by a court as an unsecured creditor, it would be at risk of losing some or all of the principal and interest involved in the transaction.
Market segment risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Market segment risk. To the extent the Fund emphasizes, from time to time, investments in a market segment, the Fund will be subject to a greater degree to the risks particular to that segment, and may experience greater market fluctuation than a fund without the same focus. Industries in the financials segment, such as banks, insurance companies, broker-dealers and real estate investment trusts (REITs), may be sensitive to changes in interest rates, credit rating downgrades, decreased liquidity in credit markets and general economic activity and are generally subject to extensive government regulation.
Valuation risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Valuation risk. Nearly all of the Fund's investments are valued using a fair value methodology. The sales price the Fund could receive for any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for illiquid securities and securities that trade in thin or volatile markets. These differences may increase significantly and affect Fund investments more broadly during periods of market volatility. The ability to value the Fund’s investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers.
Cybersecurity risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Cybersecurity risk. Cybersecurity failures by and breaches of the Fund’s Adviser, transfer agent, custodian, Fund accounting agent or other service providers may disrupt Fund operations, interfere with the Fund’s ability to calculate its NAV, prevent Fund stockholders from purchasing or selling shares or receiving distributions or receiving timely information regarding the Fund or their investment in the Fund, cause loss of or unauthorized access to private stockholder information, and result in financial losses to the Fund and its stockholders, regulatory fines, penalties, reputational damage, or additional compliance costs. New ways to carry out cyber attacks continue to develop. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund’s ability to plan for or respond to a cyber attack.
Cash management risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Cash management risk. The value of the investments held by the Fund for cash management or temporary defensive purposes may be affected by market risks, changing interest rates and by changes in credit ratings of the investments. To the extent that the Fund has any uninvested cash, the Fund would be subject to credit risk with respect to the depository institution holding the cash. If the Fund holds cash uninvested, the Fund will not earn income on the cash and the Fund’s yield will go down. During such periods, it may be more difficult for the Fund to achieve its investment objective.
Antitakeover provisions [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Anti-takeover provisions. The Fund’s Charter and Bylaws include provisions that are designed to limit the ability of other entities or persons to acquire control of the Fund for short-term objectives, including by converting the Fund to open-end status or changing the composition of the Board, that may be detrimental to the Fund’s ability to achieve its primary investment objective of seeking to provide its common stockholders with a high level of current income. These provisions include staggered terms of service for the Directors, advance notice requirements for stockholder proposals, and super-majority voting requirements for certain transactions with affiliates, open-ending the Fund or a merger, liquidation, asset sale or similar transaction. The Fund’s Bylaws also contain a provision providing that the Board of Directors has adopted a resolution to opt in the Fund to the provisions of the Maryland Control Share Acquisition Act (“MCSAA”). Such provisions may limit the ability of stockholders to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund. There can be no assurance, however, that such provisions will be sufficient to deter activist investors that seek to cause the Fund to take actions that may not be aligned with the interests of long-term stockholders. Furthermore, the law is uncertain on the use of control share provisions. Certain courts have found that control share provisions are unenforceable under the 1940 Act. It is possible that a court could decide that the Fund's decision to opt in to the MCSAA is not enforceable under the 1940 Act.
