Expense Example [Table Text Block] |  | Example As required by the relevant SEC regulations, the following example illustrates the expenses that you would pay on a $1,000 investment in each Funds' Common Shares assuming (i) total annual expenses of 3.98%, 4.69%, and 4.67% for BSL, BGX and BGB, respectively of net assets attributable to each Funds' Common Shares, (ii) a 5% annual return and (iii) reinvestment of all dividends and distributions at NAV:
| 1 Year | 3 Years | 5 Years | 10 Years
Blackstone Senior Floating Rate Term Fund | $40 | $121 | $204 | $419
Blackstone Long-Short Credit Income Fund | $47 | $141 | $236 | $476
Blackstone Strategic Credit Fund | $47 | $141 | $235 | $475
The example should not be considered a representation of future expenses. Actual expenses may be greater or less than those assumed. The example assumes that the estimated “Other expenses” set forth in the Annual Expenses table are accurate, and that all dividends and distributions are reinvested at NAV. Moreover, the Funds’ actual rate of return may be greater or less than the hypothetical 5% return shown in the example. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Investment Objectives and Practices [Text Block] |  | INVESTMENT OBJECTIVES BSL The Fund’s primary investment objective is to seek high current income, with a secondary objective to seek preservation of capital, consistent with its primary goal of high current income. There can be no assurance that the Funds will achieve their investment objectives. There have been no changes in the Funds’ investment objectives since the prior disclosure date. INVESTMENT STRATEGIES There have been no changes in the Funds' Investment Strategies since the prior disclosure date. BSL Under normal market conditions, at least 80% of the Fund’s Managed Assets will be invested in senior, secured floating rate loans (“Senior Loans”). This policy is not fundamental and may be changed by the board of trustees of the Fund with at least 60 days’ written notice provided to shareholders. Borrowers take out Senior Loans to refinance existing debt and for acquisitions, dividends, leveraged buyouts, and general corporate purposes. “Managed Assets” means the total assets of the Fund (including any assets attributable to any preferred shares that may be outstanding or to money borrowed from banks or financial institutions or issued notes for investment purposes) minus the sum of the Fund’s accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Senior Loans typically are of below investment grade quality. Below investment grade quality securities (including Senior Loans) are those that, at the time of investment, are rated Ba1 or lower by Moody’s Investors Service, Inc. (“Moody’s”) and BB+ or lower by Standard & Poor’s Corporation Ratings Group (“S&P”) or Fitch Ratings, Inc. (“Fitch”), or if unrated are determined by the Blackstone Liquid Credit Strategies LLC (the “Adviser”) to be of comparable quality. Securities of below investment grade quality, commonly referred to as “junk” or “high yield” securities, are regarded as having predominantly speculative characteristics with respect to an issuer’s capacity to pay interest and repay principal. The Fund may invest up to 20% of its Managed Assets in (i) loan interests that are not secured by any collateral of the Borrower, (ii) loan interests that have a lower than first lien priority on collateral of the Borrower, (iii) other income producing securities (including, without limitation, U.S. government debt securities and investment and non-investment grade, subordinated and unsubordinated corporate debt securities), (iv) warrants and equity securities issued by a Borrower or its affiliates as part of a package of investments in the Borrower or its affiliates and (v) structured products (including, without limitation, collateralized loan obligations, credit linked notes and derivatives, including credit derivatives). The Fund may invest in debt securities, including Senior Loans, of any credit quality, maturity and duration. The Fund may invest in U.S. dollar and non-U.S. dollar denominated securities of issuers located anywhere in the world, and of issuers that operate in any industry. The Fund may also invest in swaps, including single name credit default swaps, single name loan credit default swaps, total return swaps, interest rate swaps and foreign currency swaps. The Fund may invest up to 50% of its Managed Assets in securities that are considered illiquid. “Illiquid securities” are securities which cannot be sold within seven days in the ordinary course of business at approximately the value used by the Fund in determining its net asset value. During temporary defensive periods or in order to keep the Fund’s cash fully invested, including during the period when the net proceeds of the offering of common shares are being invested, the Fund may deviate from its investment policies and objectives. During such periods, the Fund may invest all or a portion of Managed Assets in U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the Treasury or by U.S. government agencies or instrumentalities; non-U.S. government securities which have received the highest investment grade credit rating, certificates of deposit issued against funds deposited in a bank or a savings and loan association; commercial paper; bankers’ acceptances; bank time deposits; shares of money market funds; credit linked notes; repurchase agreements with respect to any of the foregoing; asset-backed securities or any other fixed income securities that the Adviser considers consistent with this strategy. It is impossible to predict when, or for how long, the Fund will use these alternative strategies. There can be no assurance that such strategies will be successful. Percentage limitations described in this prospectus are as of the time of investment by the Fund and may be exceeded because of changes in the market value or investment rating of the Fund’s assets or if a Borrower distributes equity securities as incident to the purchase or ownership of a Senior Loan, Subordinated Loan (as defined below) or in connection with a reorganization of a Borrower. Leverage. The Fund currently utilizes leverage through borrowings, including loans from certain financial institutions and/or the issuance of debt securities (collectively, “Borrowings”), in an aggregate amount of up to 33 1/3% of its Managed Assets at the time the leverage is incurred in order to buy additional securities. The Fund may also borrow for temporary, emergency or other purposes as permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). All costs and expenses related to any form of leverage used by the Fund will be borne entirely by common shareholders. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk Factors [Table Text Block] |  | RISKS APPLICABLE TO EACH FUND Investment and Market Risk An investment in the Fund’s Common Shares is subject to investment risk, including the possible loss of the entire principal amount invested. An investment in the Fund’s Common Shares represents an indirect investment in the portfolio of floating rate instruments, other securities and derivative investments owned by the Fund, and the value of these investments may fluctuate, sometimes rapidly and unpredictably. At any point in time an investment in the Fund’s Common Shares may be worth less than the original amount invested, even after taking into account distributions paid by the Fund and the ability of common shareholders to reinvest dividends. The Fund may also use leverage, which would magnify the Fund’s investment, market and certain other risks. Below Investment Grade, or High Yield, Instruments Risk (updated since the prior disclosure date for the Funds) The Fund anticipates that it may invest substantially all of its assets in instruments that are rated below investment grade. Below investment grade instruments are commonly referred to as “junk” or “high yield” instruments and are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal. Lower grade instruments may be particularly susceptible to economic downturns. It is likely that a prolonged or deepening economic downturn could adversely affect the ability of the issuers of such instruments to repay principal and pay interest thereon, increase the incidence of default for such instruments and severely disrupt the market value of such instruments. Below investment grade instruments, though generally higher yielding, are characterized by higher risk. They may be subject to certain risks with respect to the issuing entity and to greater market fluctuations than certain lower yielding, higher rated instruments. The retail secondary market for lower grade instruments may be less liquid than that for higher rated instruments. Adverse conditions could make it difficult at times for the Fund to sell certain instruments or could result in lower prices than those used in calculating the Fund’s NAV. Because of the substantial risks associated with investments in lower grade instruments, investors could lose money on their investment in Common Shares of the Fund, both in the short-term and the long-term.” “Covenant-lite” Obligations Risk The Fund may invest in, or obtain exposure to, obligations that may be “covenant-lite,” which means such obligations lack certain financial maintenance covenants. While these loans may still contain other collateral protections, a covenant-lite loan may carry more risk than a covenant-heavy loan made by the same borrower as it does not require the borrower to provide affirmation that certain specific financial tests have been satisfied on a routine basis as is required under a covenant-heavy loan agreement. Should a loan held by the Fund begin to deteriorate in quality, the Fund’s ability to negotiate with the borrower may be delayed under a covenant-lite loan compared to a loan with full maintenance covenants. This may in turn delay the Fund’s ability to seek to recover its investment. Valuation Risk Unlike publicly traded common stock which trades on national exchanges, there is no central place or exchange for most of the Fund’s investments to trade. The Fund’s investments generally trade on an “over-the-counter” market which may be anywhere in the world where the buyer and seller can settle on a price. Due to the lack of centralized information and trading, the valuation of loans or fixed-income instruments may carry more risk than that of common stock. Uncertainties in the conditions of the financial market, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. In addition, other market participants may value securities differently than the Fund. As a result, the Fund may be subject to the risk that when an instrument is sold in the market, the amount received by the Fund is less than the value of such instrument carried on the Fund’s books. Swap Risk The Fund may also invest in credit default swaps, total return swaps and interest rate swaps. Such transactions are subject to market risk, liquidity risk, risk of default by the other party to the transaction, known as “counterparty risk,” and risk of imperfect correlation between the value of such instruments and the underlying assets and may involve commissions or other costs. When buying protection under a swap, the risk of loss with respect to swaps generally is limited to the net amount of payments that the Fund is contractually obligated to make. However, when selling protection under a swap, the risk of loss is often the notional value of the underlying asset, which can result in a loss substantially greater than the amount invested in the swap itself. The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid; however, there is no guarantee that the swap market will continue to provide liquidity. If the Adviser is incorrect in its forecasts of market values, interest rates or currency exchange rates, the investment performance of the Fund would be less favorable than it would have been if these investment techniques were not used. In a total return swap, the Fund pays the counterparty a floating short-term interest rate and receives in exchange the total return of underlying loans or debt securities (or pays an equivalent amount, if the total return is negative). The Fund bears the risk of default on the underlying loans or debt securities, based on the notional amount of the swap. The Fund would typically have to post collateral to cover potential obligations under the swap. Credit Risk Credit risk is the risk that one or more Loans or other instruments in the Fund’s portfolio will decline in price or fail to pay interest or principal when due because the issuer of the instrument experiences a decline in its financial status. While a senior position in the capital structure of a Borrower or issuer may provide some protection with respect to the Fund’s investments in certain Loans, losses may still occur because the market value of Loans is affected by the creditworthiness of Borrowers or issuers and by general economic and specific industry conditions and the Fund’s other investments will often be subordinate to other debt in the issuer’s capital structure. To the extent the Fund invests in below investment grade instruments, it will be exposed to a greater amount of credit risk than a fund which invests in investment grade securities. The prices of lower grade instruments are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade instruments. Instruments of below investment grade quality are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due and therefore involve a greater risk of default. In addition, the Fund may enter into credit derivatives which may expose it to additional risk in the event that the instruments underlying the derivatives default. Interest Rate Risk The fixed-income instruments that the Fund may invest in are subject to the risk that market values of such securities will decline as interest rates increase. These changes in interest rates have a more pronounced effect on securities with longer durations. Typically, the impact of changes in interest rates on the market value of an instrument will be more pronounced for fixed-rate instruments, such as most corporate bonds, than it will for Loans or other floating rate instruments. Fluctuations in the value of portfolio securities will not affect interest income on existing portfolio securities but will be reflected in the Fund’s NAV. Systematic Strategies Related to Bond Investments Risk With respect to the bond portion of the Fund’s portfolio, to the extent to which the proprietary model used by the Adviser (the "Model") or comparable methods or strategies are employed, certain of the Adviser’s securities analysis methods will rely on the assumption that the companies whose securities are purchased or sold, the rating agencies that review these securities, and other publicly available sources of information about these securities, are providing accurate and unbiased data. While the Adviser is alert to indications that data may be incorrect, there is always a risk that the Adviser’s analysis may be compromised by inaccurate or misleading information. The Model the Adviser intends to utilize to manage the Fund’s bond investments could lead to unsatisfactory investments. The Adviser might not be able to effectively implement the Model, and there can be no guarantee that the Fund will achieve the desired results. Certain aspects of the Adviser’s investment process with respect to the Model are dependent on complex proprietary software, which requires constant development and refinement. The Adviser has implemented procedures designed to appropriately control the development and implementation of the Model. However, analytical, coding and implementation errors present substantial risks to complex models and quantitative investment management strategies. The Adviser cannot guarantee that its internal controls will be effective in all circumstances. The Fund could be negatively affected by undetected software defects or fundamental issues with the Adviser’s method of interpreting and acting upon the Model’s output. The Adviser’s implementation of its investment strategy with respect to the Fund’s bond portfolio utilizing the Model will rely on the analytical and mathematical foundation of the Model and the incorporation of the Model’s outputs into a complex computational environment. Any such strategy is also dependent on the quality of the market data utilized by the Model, changes in credit market conditions, creation and maintenance of the Model’s software and the successful incorporation of the Model’s output into the construction of the Fund’s bond portfolio. There is always a possibility of human error in the creation, maintenance and use of the Model. Moreover, the Adviser’s portfolio managers exercise discretion in the utilization of the Model, and the investment results of the relevant portion(s) of the Fund’s investments are dependent on the ability of portfolio managers to correctly understand and implement or disregard the Model’s signals. There can be no assurance that utilizing the Model will yield better results than any other investment method. LIBOR Risk (updated since the prior disclosure date for the Funds) The United Kingdom’s Financial Conduct Authority announced a phase out of the LIBOR in 2017. Although many LIBOR rates ceased to be published or no longer are representative of the underlying market they seek to measure after December 31, 2021, a selection of widely used U.S. dollar LIBOR rates will continue to be published through June 2023 in order to assist with the transition. Further, on March 15, 2022, the Consolidated Appropriations Act of 2022, which includes the Adjustable Interest Rate (LIBOR) Act, was signed into law in the United States. This legislation establishes a uniform benchmark replacement process for financial contracts that mature after June 30, 2023 that do not contain clearly defined or practicable fallback provisions. The FRS, in conjunction with the ARRC, a steering committee comprised of large U.S. financial institutions, has begun publishing SOFR, which is their preferred alternative rate for U.S. dollar LIBOR, and which is a new index calculated by short-term repurchase agreements, backed by Treasury securities. Proposals for alternative reference rates for other currencies have also been announced or have already begun publication. Markets are in the process of developing in response to these new rates. Although financial regulators and industry working groups have suggested alternative reference rates, such as the European Interbank Offer Rate, the Sterling Overnight Interbank Average Rate and SOFR, there has been no global consensus as to an alternative rate and the process for amending existing contracts or instruments to transition away from LIBOR remains incomplete. Given the inherent differences between LIBOR and SOFR, or any other alternative benchmark rate that may be established, there remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate. In many cases, the nominated replacements, as well as other potential replacements, are not complete or ready to implement and require margin adjustments. There is currently no final consensus as to which benchmark rate(s) (along with any adjustment and/or permutation thereof) will replace all or any LIBOR tenors (i.e., the maturity period) after the discontinuation thereof and there can be no assurance that any such replacement benchmark rate(s) will attain market acceptance. Before LIBOR ceases to exist, the Fund and its underlying obligors may need to amend or restructure existing LIBOR-based debt instruments and any related hedging arrangements that extend beyond June 30, 2023, depending on the applicable LIBOR tenor. Such amendments and restructurings may be difficult, costly and time consuming. In addition, from time to time the Fund invests in floating rate loans and investment securities whose interest rates are indexed to LIBOR. Uncertainty as to the nature of alternative reference rates and as to potential changes or other reforms to LIBOR, or any changes announced with respect to such reforms, may result in a sudden or prolonged increase or decrease in the reported LIBOR rates and the value of LIBOR-based loans and securities, including those of other issuers the Fund currently owns or may in the future own. It remains uncertain how such changes would be implemented and the effects such changes would have on the Fund, issuers of instruments in which the Fund invests and financial markets generally. The expected discontinuation of LIBOR could have a significant impact on our business. There could be significant operational challenges for the transition away from LIBOR including, but not limited to, amending loan agreements with borrowers on investments that may have not been modified with fallback language and adding effective fallback language to new agreements in the event that LIBOR is discontinued before maturity. Beyond these challenges, we anticipate there may be additional risks to our current processes and information systems that will need to be identified and evaluated by us. Due to the uncertainty of the replacement for LIBOR, the potential effect of any such event on our cost of capital and net investment income cannot yet be determined. In addition, the cessation of LIBOR could:
| ● | Adversely impact the pricing, liquidity, value of, return on and trading for a broad array of financial products, including any LIBOR-linked securities, loans and derivatives that may be included in our assets and liabilities;
| ● | Require extensive changes to documentation that governs or references LIBOR or LIBOR-based products, including, for example, pursuant to time-consuming renegotiations of documentation to modify the terms of investments;
| ● | Result in inquiries or other actions from regulators in respect of our preparation and readiness for the replacement of LIBOR with one or more alternative reference rates;
| ● | Result in disputes, litigation or other actions with portfolio companies, or other counterparties, regarding the interpretation and enforceability of provisions in our LIBOR-based investments, such as fallback language or other related provisions, including, in the case of fallbacks to the alternative reference rates, any economic, legal, operational or other impact resulting from the fundamental differences between LIBOR and the various alternative reference rates;
| ● | Require the transition and/or development of appropriate systems and analytics to effectively transition our risk management processes from LIBOR-based products to those based on one or more alternative reference rates, which may prove challenging given the limited history of the proposed alternative reference rates; and
| ● | Cause us to incur additional costs in relation to any of the above factors.
There is no guarantee that a transition from LIBOR to an alternative will not result in financial market disruptions, significant increases in benchmark rates, or borrowing costs to borrowers, any of which could have a material adverse effect on our business, result of operations, financial condition, and Common Share price. In addition, the transition to a successor rate could potentially cause (i) increased volatility or illiquidity in markets for instruments that currently rely on LIBOR, (ii) a reduction in the value of certain instruments held by the Fund, or (iii) reduced effectiveness of related Fund transactions, such as hedging. It remains uncertain how such changes would be implemented and the effects such changes would have on the Fund, issuers of instruments in which the Fund invests and financial markets generally. Force Majeure Risk The Fund may be affected by force majeure events (e.g., acts of God, fire, flood, earthquakes, outbreaks of an infectious disease, pandemic or any other serious public health concern, war, terrorism, nationalization of industry and labor strikes). Force majeure events could adversely affect the ability of the Fund or a counterparty to perform its obligations. The liability and cost arising out of a failure to perform obligations as a result of a force majeure event could be considerable and could be borne by the Fund. Certain force majeure events, such as war or an outbreak of an infectious disease, could have a broader negative impact on the global or local economy, thereby affecting the Fund. Additionally, a major governmental intervention into industry, including the nationalization of an industry or the assertion of control, could result in a loss to the Fund if an investment is affected, and any compensation provided by the relevant government may not be adequate. Epidemic and Pandemic Risk The world has been susceptible to epidemics/pandemics, most recently COVID-19, which has been designated as a pandemic by the World Health Organization. Any outbreak of COVID-19, SARS, H1N1/09 flu, avian flu, other coronavirus, Ebola or other existing or new epidemics/pandemics, or the threat thereof, together with any resulting restrictions on travel or quarantines imposed, has had, and will continue to have, an adverse impact on the economy and business activity globally (including in the countries in which the Fund invests), and thereby is expected to adversely affect the performance of the Fund’s investments and the Fund’s ability to fulfill its investment objectives. Furthermore, the rapid development of epidemics/pandemics could preclude prediction as to their ultimate adverse impact on economic and market conditions, and, as a result, presents material uncertainty and risk with respect to the Fund and the performance of its investments. COVID-19 Risk (deleted since the prior disclosure date for the Funds) Market Disruption and Geopolitical Risk (updated since the prior disclosure date for the Funds) The Fund may be adversely affected by uncertainties such as terrorism, international political developments, and changes in government policies, taxation, restrictions on foreign investment and currency repatriation, currency fluctuations and other developments in the laws and regulations of the countries in which it is invested. Likewise, natural and environmental disasters, epidemics or pandemics, and systemic market dislocations may be highly disruptive to economies and markets. See “—Epidemic and Pandemic Risk” above. Uncertainties and events around the world may (i) result in market volatility, (ii) have long-term effects on the U.S. and worldwide financial markets and (iii) cause further economic uncertainties in the United States and worldwide. The Fund cannot predict the effects of geopolitical events in the future on the U.S. economy and securities markets. Additionally, certain of the Funds’ investments may operate in, or have dealings with, countries subject to sanctions or embargos imposed by the U.S. government, foreign governments, or the United Nations or other international organizations. For example, the ongoing conflict due to Russia’s invasion of Ukraine and the rapidly evolving measures in response could be expected to have a negative impact on the economy and business activity globally (including in the countries in which the Funds invest). The severity and duration of the conflict and its impact on global economic and market conditions are impossible to predict, and as a result, present material uncertainty and risk with respect to the Funds and their investments and operations, and the ability of the Funds to achieve their investment objectives. Sanctions could also result in Russia taking counter measures or retaliatory actions which could adversely impact the Funds' business or the business of the Funds' investments, including, but not limited to, cyberattacks targeting private companies, individuals or other infrastructure upon which the Funds' business and the business of the Funds' portfolio companies or obligors rely. Lender Liability Risk A number of U.S. judicial decisions have upheld judgments obtained by Borrowers against lending institutions on the basis of various evolving legal theories, collectively termed “lender liability.” Generally, lender liability is founded on the premise that a lender has violated a duty (whether implied or contractual) of good faith, commercial reasonableness and fair dealing, or a similar duty owed to the Borrower or has assumed an excessive degree of control over the Borrower resulting in the creation of a fiduciary duty owed to the Borrower or its other creditors or shareholders. Because of the nature of its investments, the Fund may be subject to allegations of lender liability. In addition, under common law principles that in some cases form the basis for lender liability claims, if a lender or bondholder (a) intentionally takes an action that results in the undercapitalization of a Borrower to the detriment of other creditors of such Borrower, (b) engages in other inequitable conduct to the detriment of such other creditors, (c) engages in fraud with respect to, or makes misrepresentations to, such other creditors or (d) uses its influence as a stockholder to dominate or control a Borrower to the detriment of other creditors of such Borrower, a court may elect to subordinate the claim of the offending lender or bondholder to the claims of the disadvantaged creditor or creditors, a remedy called “equitable subordination.” Because affiliates of, or persons related to, the Adviser may hold equity or other interests in obligors of the Fund, the Fund could be exposed to claims for equitable subordination or lender liability or both based on such equity or other holdings. Counterparty Risk The Fund is subject to credit risk with respect to the counterparties to its derivatives contracts (whether a clearing corporation in the case of exchange-traded instruments or our hedge counterparty in the case of OTC instruments) purchased by the Fund. Counterparty risk is the risk that the other party in a derivative transaction will not fulfill its contractual obligation. Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to their derivative transactions will affect the value of those instruments. By entering into derivatives, the Fund assumes the risks that theses counterparties could experience financial or other hardships that could call into question their continued ability to perform their obligations. In the case of a default by the counterparty, the Fund could become subject to adverse market movements while replacement transactions are executed. The ability of the Fund to transact business with any one or number of counterparties, the possible lack of a meaningful and independent evaluation of such counterparties’ financial capabilities, and the absence of a regulated market to facilitate settlement may increase the potential for losses by the Fund. Furthermore, concentration of derivatives in any particular counterparty would subject the Fund to an additional degree of risk with respect to defaults by such counterparty. The Adviser evaluates and monitors the creditworthiness of counterparties in order to ensure that such counterparties can perform their obligations under the relevant agreements. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial or other difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a dissolution, assignment for the benefit of creditors, liquidation, winding-up, bankruptcy or other analogous proceedings. In addition, in the event of the insolvency of a counterparty to a derivative transaction, the derivative contract would typically be terminated at its fair market value. If the Fund is owed this fair market value upon the termination of the derivative contract and its claim is unsecured, the Fund will be treated as a general creditor of such counterparty, and will not have any claim with respect to the underlying assets. The Fund may obtain only a limited recovery or may obtain no recovery at all in such circumstances. In addition, regulations that were adopted by prudential regulators in 2019 require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many derivatives contracts, terms that delay or restrict the rights of counterparties, such as the Fund, to terminate such contracts, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that such counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. Certain categories of interest rate and credit default swaps are subject to mandatory clearing, and more categories may be subject to mandatory clearing in the future. The counterparty risk for cleared derivatives is generally lower than for uncleared OTC derivative transactions because generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing house for performance of financial obligations. However, there can be no assurance that a clearing house, or its members, will satisfy the clearing house’s obligations (including, but not limited to, financial obligations and legal obligations to segregate margins collected by the clearing house) to the Fund. Counterparty risk with respect to certain exchange-traded and over-the-counter derivatives may be further complicated by recently enacted U.S. financial reform legislation. Potential Conflicts of Interest Risk The Adviser will be subject to certain conflicts of interest in its management of the Fund. These conflicts will arise primarily from the involvement of the Adviser, Blackstone Alternative Credit Advisors LP (“Blackstone Credit”), Blackstone Inc. (“Blackstone”) and their affiliates in other activities that may conflict with those of the Fund. The Adviser, Blackstone Credit, Blackstone and their affiliates engage in a broad spectrum of activities. In the ordinary course of their business activities, the Adviser, Blackstone Credit, Blackstone and their affiliates may engage in activities where the interests of certain divisions of the Adviser, Blackstone Credit, Blackstone and their affiliates or the interests of their clients may conflict with the interests of the Fund or the common shareholders. Other present and future activities of the Adviser, Blackstone Credit, Blackstone and their affiliates may give rise to additional conflicts of interest, which may have a negative impact on the Fund. In addressing these conflicts and regulatory, legal and contractual requirements across its various businesses, Blackstone has implemented certain policies and procedures (e.g., information walls) that may reduce the positive firm-wide synergies that the Adviser may have potentially utilized for purposes of finding attractive investments. Additionally, Blackstone may limit a client and/or its portfolio companies from engaging in agreements with or related to companies in which any fund of Blackstone has or has considered making an investment or which is otherwise an advisory client of Blackstone and/or from time to time restrict or otherwise limit the ability of the Fund to make investments in or otherwise engage in businesses or activities competitive with companies or other clients of Blackstone, either as result of contractual restrictions or otherwise. Finally, Blackstone has in the past entered, and is likely in the future to enter, into one or more strategic relationships in certain regions or with respect to certain types of investments that, although possibly intended to provide greater opportunities for the Fund, may require the Fund to share such opportunities or otherwise limit the amount of an opportunity the Fund can otherwise take. As part of its regular business, Blackstone provides a broad range of services other than those provided by the Adviser, including investment banking, underwriting, capital markets syndication and advisory (including underwriting), placement, financial advisory, restructuring and advisory, consulting, asset/property management, mortgage servicing, insurance (including title insurance), monitoring, commitment, syndication, origination, servicing, management consulting and other similar operational and finance matters, healthcare consulting/brokerage, group purchasing, organizational, operational, loan servicing, financing, divestment and other services. In addition, Blackstone may provide services in the future beyond those currently provided. The Fund will not receive a benefit from the fees or profits derived from such services. In such a case, a client of Blackstone would typically require Blackstone to act exclusively on its behalf. This request may preclude all of Blackstone clients (including the Fund) from participating in related transactions that would otherwise be suitable. Blackstone will be under no obligation to decline any such engagements in order to make an investment opportunity available to the Fund. In connection with its other businesses, Blackstone will likely come into possession of information that limits its ability to engage in potential transactions. The Fund’s activities are expected to be constrained as a result of the inability of the personnel of Blackstone to use such information. For example, employees of Blackstone from time to time are prohibited by law or contract from sharing information with members of the Adviser’s investment team that would be relevant to monitoring the Fund’s portfolio and other investment decisions. Additionally, there are expected to be circumstances in which one or more of certain individuals associated with Blackstone will be precluded from providing services related to the Fund’s activities because of certain confidential information available to those individuals or to other parts of Blackstone (e.g., trading may be restricted). Blackstone has long term relationships with a significant number of corporations and their senior management. In determining whether to invest in a particular transaction on behalf of the Fund, the Adviser will consider those relationships, and may decline to participate in a transaction as a result of such relationships. To the extent permitted by the 1940 Act, the Fund may also co-invest with clients of Blackstone in particular investment opportunities, and the relationship with such clients could influence the decisions made by the Adviser with respect to such investments. The Fund may be forced to sell or hold existing investments (possibly at disadvantageous times or under disadvantageous conditions) as a result of various relationships that Blackstone may have or transactions or investments Blackstone and its affiliates may make or have made. The inability to transact in any security, derivative or loan held by the Fund could result in significant losses or lost opportunity costs to the Fund. Limitations on Transactions with Affiliates Risk The 1940 Act limits our ability to enter into certain transactions with certain of our affiliates. As a result of these restrictions, we may be prohibited from buying or selling any security directly from or to any portfolio company of or private equity fund managed by Blackstone, Blackstone Credit or any of their respective affiliates. However, the Fund may under certain circumstances purchase any such portfolio company’s loans or securities in the secondary market, which could create a conflict for the Adviser between the interests of the Fund and the portfolio company, in that the ability of the Adviser to recommend actions in the best interest of the Fund might be impaired. The 1940 Act also prohibits certain “joint” transactions with certain of our affiliates, which could include investments in the same portfolio company (whether at the same or different times). These limitations may limit the scope of investment opportunities that would otherwise be available to us. Although the Fund has received an exemptive order from the SEC that permits it, among other things, to co-invest with certain affiliates of the Adviser and certain funds managed and controlled by the Adviser and its affiliates, it may only do so in accordance with certain terms and conditions that limit the types of transactions the Fund may engage in. Dependence on Key Personnel Risk The Adviser is dependent upon the experience and expertise of certain key personnel in providing services with respect to the Fund’s investments. If the Adviser were to lose the services of these individuals, its ability to service the Fund could be adversely affected. As with any managed fund, the Adviser may not be successful in selecting the best-performing securities or investment techniques for the Fund’s portfolio and the Fund’s performance may lag behind that of similar funds. The Adviser has informed the Fund that the investment professionals associated with the Adviser are actively involved in other investment activities not concerning the Fund and will not be able to devote all of their time to the Fund’s business and affairs. In addition, individuals not currently associated with the Adviser may become associated with the Fund and the performance of the Fund may also depend on the experience and expertise of such individuals. Prepayment Risk During periods of declining interest rates, Borrowers or issuers may exercise their option to prepay principal earlier than scheduled. For fixed rate securities, such payments often occur during periods of declining interest rates, forcing the Fund to reinvest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions to common shareholders. This is known as prepayment or “call” risk. Below investment grade instruments frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met (“call protection”). An issuer may redeem a below investment grade instrument if, for example, the issuer can refinance the debt at a lower cost due to declining interest rates or an improvement in the credit standing of the issuer. Loans and the loans underlying CLOs in which the Fund invests typically do not have call protection after a certain period from initial issuance. For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be enhanced. UK Exit from the EU The UK formally left the EU on January 31, 2020 (commonly known as “Brexit”), subject to a transition period that ended on December 31, 2020. During an 11-month transition period, the United Kingdom, including its businesses and people, abided by applicable EU rules, honored the United Kingdom’s trade relationships with EU countries, and prepared for the new post-Brexit rules which took effect on January 1, 2021. Since the June 2016 referendum in the UK, global financial markets have experienced significant volatility due to the uncertainty around Brexit. There will likely continue to be considerable uncertainty as to the longer term economic, legal, political and social framework to be put in place between the UK and the EU, in particular as to the arrangements which will apply to its relationships with the EU and with other countries. This process and/or the uncertainty associated with it may adversely affect the return on investments economically tied to the UK (and consequently the Fund). This may be due to, among other things: (i) increased uncertainty and volatility in UK, EU and other financial markets; (ii) fluctuations in asset values; (iii) fluctuations in exchange rates; (iv) increased illiquidity of investments located, listed or traded within the UK, the EU or elsewhere; (v) changes in the willingness or ability of financial and other counterparties to enter into transactions, or the price at which and terms on which they are prepared to transact; and/or (vi) changes in legal and regulatory regimes to which the Fund’s investments are or become subject. Repurchase Agreements Risk Subject to its investment objectives and policies, the Fund may invest in repurchase agreements as a buyer for investment purposes. Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. The Fund does not bear the risk of a decline in the value of the underlying security unless the seller defaults under its repurchase obligation. In the event of the bankruptcy or other default of a seller of a repurchase agreement, the Fund could experience both delays in liquidating the underlying securities and losses, including (1) possible decline in the value of the underlying security during the period in which the Fund seeks to enforce its rights thereto; (2) possible lack of access to income on the underlying security during this period; and (3) expenses of enforcing its rights. In addition, as described above, the value of the collateral underlying the repurchase agreement will be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, the Fund generally will seek to liquidate such collateral. However, the exercise of the Fund’s right to liquidate such collateral could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Fund could suffer a loss. Reverse Repurchase Agreements Risk The Fund’s use of reverse repurchase agreements involves many of the same risks involved in the Fund’s use of leverage, as the proceeds from reverse repurchase agreements generally will be invested in additional securities. There is a risk that the market value of the securities acquired in the reverse repurchase agreement may decline below the price of the securities that the Fund has sold but remains obligated to repurchase. In addition, there is a risk that the market value of the securities retained by the Fund may decline. If the buyer of securities under a reverse repurchase agreement were to file for bankruptcy or experiences insolvency, the Fund may be adversely affected. Also, in entering into reverse repurchase agreements, the Fund would bear the risk of loss to the extent that the proceeds of the reverse repurchase agreement are less than the value of the underlying securities. In addition, due to the interest costs associated with reverse repurchase agreements transactions, the Fund’s NAV will decline, and, in some cases, the Fund may be worse off than if it had not used such instruments. Investments in Equity Securities or Warrants Incidental to Investments in Fixed Income Instruments From time to time the Fund also may invest in or hold common stock and other equity securities or warrants incidental to the purchase or ownership of a fixed income instrument or in connection with a reorganization of an issuer. Investments in equity securities incidental to investments in fixed income instruments entail certain risks in addition to those associated with investments in fixed income instruments. Because equity is merely the residual value of an issuer after all claims and other interests, it is inherently more risky than the bonds or loans of the same issuer. The value of the equity securities may be affected more rapidly, and to a greater extent, by company-specific developments and general market conditions. These risks may increase fluctuations in the Fund's NAV. The Fund frequently may possess material non-public information about a Borrower or issuer as a result of its ownership of a fixed income instrument. Because of prohibitions on trading in securities while in possession of material non-public information, the Fund might be unable to enter into a transaction in a security of an issuer when it would otherwise be advantageous to do so. Inflation/Deflation Risk Inflation risk is the risk that the value of certain assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Shares and Preferred Shares, and distributions thereon, can decline. In addition, during any periods of rising inflation, the dividend rates or borrowing costs associated with the Fund’s use of leverage would likely increase, which would tend to further reduce returns to common shareholders. Deflation risk is the risk that prices throughout the economy decline over time—the opposite of inflation. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer defaults more likely, which may result in a decline in the value of the Fund’s portfolio. U.S. Government Debt Securities Risk U.S. government debt securities generally do not involve the credit risks associated with investments in other types of debt securities, although, as a result, the yields available from U.S. government debt securities are generally lower than the yields available from other securities. Like other debt securities, however, the values of U.S. government securities change as interest rates fluctuate. Fluctuations in the value of portfolio securities will not affect interest income on existing portfolio securities but will be reflected in the Fund’s NAV. Since the magnitude of these fluctuations will generally be greater at times when the Fund’s average maturity is longer, under certain market conditions the Fund may, for temporary defensive purposes, accept lower current income from short-term investments rather than investing in higher yielding long-term securities. In addition, the recent economic crisis in the United States has negatively impacted government-sponsored entities, which include Federal Home Loan Banks, Fannie Mae and Freddie Mac. As the real estate market has deteriorated through declining home prices and increasing foreclosure, government-sponsored entities, which back the majority of U.S mortgages, have experienced extreme volatility and in some cases a lack of liquidity. In September 2008, Fannie Mae and Freddie Mac were placed under a conservatorship of the U.S. federal government. Any Fund investments issued by Federal Home Loan Banks and Fannie Mae may ultimately lose value. Cyber-Security Risk and Identity Theft Risks The Fund’s operations are highly dependent on the Adviser’s information systems and technology and the Fund relies heavily on the Adviser’s financial, accounting, communications and other data processing systems. The Adviser’s systems may fail to operate properly or become disabled as a result of tampering or a breach of its network security systems or otherwise. In addition, the Adviser’s systems face ongoing cybersecurity threats and attacks. Attacks on the Adviser’s systems could involve, and in some instances have in the past involved, attempts intended to obtain unauthorized access to its proprietary information, destroy data or disable, degrade or sabotage its systems, or divert or otherwise steal funds, including through the introduction of computer viruses, “phishing” attempts and other forms of social engineering. Cyberattacks and other security threats could originate from a wide variety of external sources, including cyber criminals, nation state hackers, hacktivists and other outside parties. Cyberattacks and other security threats could also originate from the malicious or accidental acts of insiders, such as employees of the Adviser. There has been an increase in the frequency and sophistication of the cyber and security threats the Adviser faces, with attacks ranging from those common to businesses to those that are more advanced and persistent, which may target the Adviser because, as an alternative asset management firm, the Adviser holds a significant amount of confidential and sensitive information about its investors, its portfolio companies or obligors (as applicable) and potential investments. As a result, the Adviser may face a heightened risk of a security breach or disruption with respect to this information. There can be no assurance that measures the Adviser takes to ensure the integrity of its systems will provide protection, especially because cyberattack techniques used change frequently or are not recognized until successful. If the Adviser’s systems are compromised, do not operate properly or are disabled, or it fails to provide the appropriate regulatory or other notifications in a timely manner, the Adviser could suffer financial loss, a disruption of its businesses, liability to its investment funds and fund investors, including the Fund and common shareholders, regulatory intervention or reputational damage. The costs related to cyber or other security threats or disruptions may not be fully insured or indemnified by other means. In addition, the Fund could also suffer losses in connection with updates to, or the failure to timely update, the Adviser’s information systems and technology. In addition, the Adviser has become increasingly reliant on third party service providers for certain aspects of its business, including for the administration of certain funds, as well as for certain information systems and technology, including cloud-based services. These third party service providers could also face ongoing cyber security threats and compromises of their systems and as a result, unauthorized individuals could gain, and in some past instances have gained, access to certain confidential data. Cybersecurity has become a top priority for regulators around the world. Many jurisdictions in which the Adviser operates have laws and regulations relating to data privacy, cybersecurity and protection of personal information, including, as examples, the General Data Protection Regulation in the EU and that went into effect in May 2018 and the California Consumer Privacy Act that went into effect in January 2020. Some jurisdictions have also enacted laws requiring companies to notify individuals and government agencies of data security breaches involving certain types of personal data. Breaches in security, whether malicious in nature or through inadvertent transmittal or other loss of data, could potentially jeopardize the Adviser, its employees’ or the Fund’s investors’ or counterparties’ confidential, proprietary and other information processed and stored in, and transmitted through, the Adviser’s computer systems and networks, or otherwise cause interruptions or malfunctions in its, its employees’, the Fund’s investors’, the Fund’s counterparties’ or third parties’ business and operations, which could result in significant financial losses, increased costs, liability to the Fund’s investors and other counterparties, regulatory intervention and reputational damage. Furthermore, if the Adviser fails to comply with the relevant laws and regulations or fail to provide the appropriate regulatory or other notifications of breach in a timely matter, it could result in regulatory investigations and penalties, which could lead to negative publicity and reputational harm, and may cause the Fund’s investors and clients to lose confidence in the effectiveness of its security measures. Obligors of the Fund also rely on data processing systems and the secure processing, storage and transmission of information, including payment and health information. A disruption or compromise of these systems could have a material adverse effect on the value of these businesses. The Fund may invest in strategic assets having a national or regional profile or in infrastructure, the nature of which could expose it to a greater risk of being subject to a terrorist attack or security breach than other assets or businesses. Such an event may have material adverse consequences on the Fund’s investment or assets of the same type or may require obligors of the Fund to increase preventative security measures or expand insurance coverage. Finally, the Adviser’s and the Fund’s technology, data and intellectual property and the technology, data and intellectual property of their portfolio companies or obligors (as applicable) are also subject to a heightened risk of theft or compromise to the extent the Adviser and the Fund’s portfolio companies or obligors (as applicable) engage in operations outside the United States, in particular in those jurisdictions that do not have comparable levels of protection of proprietary information and assets such as intellectual property, trademarks, trade secrets, know-how and customer information and records. In addition, the Adviser and the Fund and their portfolio companies or obligors (as applicable) may be required to compromise protections or forego rights to technology, data and intellectual property in order to operate in or access markets in a foreign jurisdiction. Any such direct or indirect compromise of these assets could have a material adverse impact on the Adviser and the Fund and their portfolio companies or obligors (as applicable). Portfolio Turnover Risk The Fund’s annual portfolio turnover rate may vary greatly from year to year, as well as within a given year. However, portfolio turnover rate is not considered a limiting factor in the execution of investment decisions for the Fund. High portfolio turnover may result in the realization of net short-term capital gains by the Fund which, when distributed to common shareholders, will be taxable as ordinary income. A high portfolio turnover may increase the Fund’s current and accumulated earnings and profits, resulting in a greater portion of the Fund’s distributions being treated as a dividend to the Fund’s common shareholders. In addition, a higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. Government Intervention in the Financial Markets The recent instability in the financial markets has led the U.S. government to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility, and in some cases a lack of liquidity. Federal, state, and other governments, their regulatory agencies or self-regulatory organizations may take additional actions that affect the regulation of the securities or structured products in which the Fund invests, or the issuers of such securities or structured products, in ways that are unforeseeable. Borrowers under Secured Loans held by the Fund may seek protection under the bankruptcy laws. Legislation or regulation may also change the way in which the Fund itself is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objectives. The Adviser will monitor developments and seek to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objectives, but there can be no assurance that it will be successful in doing so. Inflation and Supply Chain Risk (updated since the prior disclosure date for the Funds) Economic activity has continued to accelerate across sectors and regions. Nevertheless, due to global supply chain issues, a rise in energy prices and strong consumer demand as economies continue to reopen, inflation has increased in the U.S. and globally. Inflation is likely to continue in the near to medium-term, particularly in the U.S., with the possibility that monetary policy may continue to tighten in response. There can be no assurance that inflation will not become a serious problem in the future and have an adverse impact on the Fund’s returns. FUND SPECIFIC RISKS BSL Derivatives Risk (updated since the Fund’s prior disclosure date) Under normal market conditions, the use of derivatives by the Fund, other than for hedging purposes, will not exceed 20% of the Fund’s Managed Assets on a mark-to-market basis. The Fund’s use of derivative instruments may be speculative and involves investment risks and transaction costs to which the Fund would not be subject absent the use of these instruments, and the use of derivatives generally involves leverage in the sense that the investment exposure created by the derivatives may be significantly greater than the Fund’s initial investment in the derivatives. In some cases, the use of derivatives may result in losses in excess of principal or greater than if they had not been used. The ability to successfully use derivative instruments depends on the ability of the Adviser. The skills needed to employ derivatives strategies are different from those needed to select a portfolio security and, in connection with such strategies, the Adviser must make predictions with respect to market conditions, liquidity, currency movements, market values, interest rates and other applicable factors, which may be inaccurate. The use of derivative instruments may require the Fund to sell or purchase portfolio securities at inopportune times or for prices below or above the current market values, may limit the amount of appreciation the Fund can realize on an investment or may cause the Fund to hold a security that it might otherwise want to sell. The Fund may also have to defer closing out certain derivative positions to avoid adverse tax consequences and there may be situations in which derivative instruments are not elected that result in losses greater than if such instruments had been used. Amounts paid by the Fund as premiums and cash or other assets held in margin accounts with respect to the Fund’s derivative instruments would not be available to the Fund for other investment purposes, which may result in lost opportunities for gain. Changes to the derivatives markets as a result of the continuous promulgation of rules under the Dodd-Frank Act and other government or international and other government regulation may also have an adverse effect on the Fund’s ability to make use of derivative transactions. In addition, the use of derivatives is subject to other risks, each of which may create additional risk of loss, including liquidity risk, interest rate risk, credit risk and management risk as well as the following risks:
| ● | Correlation Risk. Imperfect correlation between the value of derivative instruments and the underlying assets of the Fund creates the possibility that the loss on such instruments may be greater than the gain in the value of the underlying assets in the Fund’s portfolio.
| ● | Duration Mismatch Risk. The duration of a derivative instrument may be significantly different than the duration of the related liability or asset.
| ● | Valuation Risk. The prices of derivative instruments, including swaps, futures, forwards and options, could be highly volatile and such instruments may subject us to significant losses. The value of such derivatives also depends upon the price of the underlying asset, reference rate or index, which may also be subject to volatility. In addition, actual or implied daily limits on price fluctuations and speculative position limits on the exchanges or over-the-counter markets in which we may conduct our transactions in derivative instruments may prevent prompt liquidation of positions, subjecting us to the potential of greater losses. In addition, significant disparities may exist between “bid” and “asked” prices for derivative instruments that are traded over-the-counter and not on an exchange.
| ● | Liquidity Risk. Derivative instruments, especially when purchased in large amounts, may not be liquid in all circumstances, so that in volatile markets we may not be able to close out a position without incurring a loss.
| ● | Counterparty Risk. Derivative instruments also involve exposure to counterparty risk, since contract performance depends in part on the financial condition of the counterparty.
In addition, the Adviser may cause the Fund to invest in derivative instruments that are neither presently contemplated nor currently available, but which may be developed in the future, to the extent such opportunities are both consistent with the Fund’s investment objectives and legally permissible. Any such investments may expose the Fund to unique and presently indeterminate risks, the impact of which may not be capable of determination until such instruments are developed and/or the Adviser determines to make such an investment on behalf of the Fund. Rule 18f-4 requires registered investment companies to adopt a written policies and procedures reasonably designed to manage the Fund’s derivatives risks. In the event that the Fund’s derivatives exposure exceeds 10% of its net assets, the Fund will be required to adopt a written derivatives risk management program and comply with a value-at-risk based limit on leverage risk. The Board of Trustees has an oversight role in ensuring these new requirements are being taken into account and, if required, will appoint a derivatives risk manager to handle the day-to-day responsibilities of the derivatives risk management program. Senior Loans Risk Under normal market conditions, the Fund will invest at least 80% of its Managed Assets in Senior Loans. This policy is not fundamental and may be changed by the board of trustees of the Fund with at least 60 days’ written notice provided to shareholders. Senior Loans hold the most senior position in the capital structure of a business entity, are secured with specific collateral and have a claim on the assets and/or stock of the Borrower that is senior to that held by unsecured creditors, subordinated debt holders and stockholders of the Borrower. Senior Loans are usually rated below investment grade or may also be unrated. As a result, the risks associated with Senior Loans are similar to the risks of below investment grade securities, although Senior Loans are senior and secured in contrast to other below investment grade securities, which are often subordinated or unsecured. Nevertheless, if a Borrower under a Senior Loan defaults or goes into bankruptcy, the Fund may recover only a fraction of what is owed on the Senior Loan or nothing at all. Senior Loans are subject to a number of risks described elsewhere in this Prospectus, including credit risk, liquidity risk and management risk. There is less readily available and reliable information about most Senior Loans than is the case for many other types of securities, including securities issued in transactions registered under the Securities Act of 1933, as amended, or registered under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). As a result, the Adviser will rely primarily on its own evaluation of a Borrower’s credit quality rather than on any available independent sources. Therefore, the Fund will be particularly dependent on the analytical abilities of the Adviser. The Fund will typically invest in Senior Loans rated below investment grade, which are considered speculative because of the credit risk of their issuers. Such companies are more likely than investment grade issuers to default on their payments of interest and principal owed to the Fund, and such defaults could reduce the Fund’s net asset value and income distributions. An economic downturn would generally lead to a higher non-payment rate, and a Senior Loan may lose significant market value before a default occurs. Moreover, any specific collateral used to secure a Senior Loan may decline in value or become illiquid, which would adversely affect the Senior Loan’s value. In general, the secondary trading market for Senior Loans is not well developed. No active trading market may exist for certain Senior Loans, which may make it difficult to value them. Illiquidity and adverse market conditions may mean that the Fund may not be able to sell Senior Loans quickly or at a fair price. To the extent that a secondary market does exist for certain Senior Loans, the market for them may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Senior Loans and other variable rate debt instruments are subject to the risk of payment defaults of scheduled interest or principal. Such payment defaults would result in a reduction of income to the Fund, a reduction in the value of the investment and a potential decrease in the net asset value of the Fund. Similarly, a sudden and significant increase in market interest rates may increase the risk for payment defaults and cause a decline in the value of these investments and in the Fund’s net asset value. Other factors (including, but not limited to, rating downgrades, credit deterioration, a large downward movement in stock prices, a disparity in supply and demand of certain securities or market conditions that reduce liquidity) can reduce the value of Senior Loans and other debt obligations, impairing the Fund’s net asset value. Although the Senior Loans in which the Fund will invest will be secured by collateral, there can be no assurance that such collateral could be readily liquidated or that the liquidation of such collateral would satisfy the Borrower’s obligation in the event of non-payment of scheduled interest or principal. In the event of the bankruptcy or insolvency of a Borrower, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a Senior Loan. In the event of a decline in the value of the already pledged collateral, if the terms of a Senior Loan do not require the Borrower to pledge additional collateral, the Fund will be exposed to the risk that the value of the collateral will not at all times equal or exceed the amount of the Borrower’s obligations under the Senior Loans. To the extent that a Senior Loan is collateralized by stock in the Borrower or its subsidiaries, such stock may lose some or all of its value in the event of the bankruptcy or insolvency of the Borrower. Those Senior Loans that are under-collateralized involve a greater risk of loss. Some Senior Loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the Senior Loans to presently existing or future indebtedness of the Borrower or take other action detrimental to lenders, including the Fund. Such court action could under certain circumstances include invalidation of Senior Loans. If legislation or state or federal regulations impose additional requirements or restrictions on the ability of financial institutions to make loans, the availability of Senior Loans for investment by the Fund may be adversely affected. In addition, such requirements or restrictions could reduce or eliminate sources of financing for certain Borrowers. This would increase the risk of default. If legislation or federal or state regulations require financial institutions to increase their capital requirements this may cause financial institutions to dispose of Senior Loans that are considered highly levered transactions. Such sales could result in prices that, in the opinion of the Adviser, do not represent fair value. If the Fund attempts to sell a Senior Loan at a time when a financial institution is engaging in such a sale, the price the Fund could get for the Senior Loan may be adversely affected. The Fund may acquire Senior Loans through assignments or participations. The Fund will typically acquire Senior Loans through assignment and may elevate a participation interest into an assignment as soon as practicably possible. The purchaser of an assignment typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the purchaser’s rights can be more restricted than those of the assigning institution, and the Fund may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. A participation typically results in a contractual relationship only with the institution participating out the interest, not with the Borrower. Sellers of participations typically include banks, broker-dealers, other financial institutions and lending institutions. The Adviser has adopted best execution procedures and guidelines to mitigate credit and counterparty risk in the atypical situation when the Fund must acquire a Senior Loan through a participation. The Adviser has established a risk and valuation committee that regularly reviews each broker-dealer counterparty for, among other things, its quality and the quality of its execution. The established procedures and guidelines require trades to be placed for execution only with broker-dealer counterparties approved by the risk and valuation committee of the Adviser. The factors considered by the committee when selecting and approving brokers and dealers include, but are not limited to: (i) quality, accuracy, and timeliness of execution, (ii) review of the reputation, financial strength and stability of the financial institution, (iii) willingness and ability of the counterparty to commit capital, (iv) ongoing reliability and (v) access to underwritten offerings and secondary markets. In purchasing participations, the Fund generally will have no right to enforce compliance by the Borrower with the terms of the loan agreement against the Borrower, and the Fund may not directly benefit from the collateral supporting the debt obligation in which it has purchased the participation. As a result, the Fund will be exposed to the credit risk of both the Borrower and the institution selling the participation. Further, in purchasing participations in lending syndicates, the Fund will not be able to conduct the due diligence on the Borrower or the quality of the Senior Loan with respect to which it is buying a participation that the Fund would otherwise conduct if it were investing directly in the Senior Loan, which may result in the Fund being exposed to greater credit or fraud risk with respect to the Borrower or the Senior Loan than the Fund expected when initially purchasing the participation. The Fund may obtain exposure to Senior Loans through the use of derivative instruments, which have become increasingly available. Although the Fund does not have an intention to do so, the Fund may utilize these instruments and similar instruments that may be available in the future. Derivative transactions involve the risk of loss due to unanticipated adverse changes in securities prices, interest rates, the inability to close out a position, imperfect correlation between a position and the desired hedge, tax constraints on closing out positions and portfolio management constraints on securities subject to such transactions. The potential loss on derivative instruments may be substantial relative to the initial investment therein. The Fund may also be subject to the risk that the counterparty in a derivative transaction will default on its obligations. Subordinated Loans Risk The Fund may invest up to 20% of its Managed Assets in Subordinated Loans. Subordinated Loans generally are subject to similar risks as those associated with investments in Senior Loans except that such loans are subordinated in payment and/or lower in lien priority to first lien holders. In the event of default on a Subordinated Loan, the first priority lien holder has first claim to the underlying collateral of the loan. Subordinated Loans 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 unsecured or 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. Subordinated Loans generally have greater price volatility than Senior Loans and may be less liquid. Structured Products Risk The Fund may invest up to 20% of its Managed Assets in structured products, including, without limitation, CLOs, structured notes, credit linked notes and derivatives, including credit derivatives. Holders of structured products bear risks of the underlying investments, index or reference obligation and are subject to counterparty risk. The Fund may have the right to receive payments only from the structured product, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain structured products enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in structured products generally pay their share of the structured product’s administrative and other expenses. Although it is difficult to predict whether the prices of indices and securities underlying structured products will rise or fall, these prices (and, therefore, the prices of structured products) will be influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a structured product uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining short-term financing, which may adversely affect the value of the structured products owned by the Fund. Certain structured products may be thinly traded or have a limited trading market. CLOs are typically privately offered and sold. As a result, investments in CLOs may be characterized by the Fund as illiquid securities. In addition to the general risks associated with debt securities discussed herein, CLOs carry additional risks, including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the investments in CLOs are subordinate to other classes or tranches thereof; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results. Investments in structured notes involve risks, including credit risk and market risk. Where the Fund’s investments in structured notes are based upon the movement of one or more factors, including currency exchange rates, interest rates, referenced bonds and stock indices, depending on the factor used and the use of multipliers or deflators, changes in interest rates and movement of the factor may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured note to be reduced to zero, and any further changes in the reference instrument may then reduce the principal amount payable on maturity. Structured notes may be less liquid than other types of securities and more volatile than the reference instrument or security underlying the note. CLO Risk In addition to the general risks associated with debt securities and structured products discussed herein, CLOs carry additional risks, including, but not limited to (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the investments in CLOs are subordinate to other classes or tranches thereof, (iv) the potential of spread compression in the underlying loans of the CLO, which could reduce credit enhancement in the CLOs and (v) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results. CLO junior debt securities that the Fund may acquire are subordinated to more senior tranches of CLO debt. CLO junior debt securities are subject to increased risks of default relative to the holders of superior priority interests in the same securities. In addition, at the time of issuance, CLO equity securities are under-collateralized in that the liabilities of a CLO at inception exceed its total assets. Though not exclusively, the Fund will typically be in a first loss or subordinated position with respect to realized losses on the assets of the CLOs in which it is invested. The Fund may recognize phantom taxable income from its investments in the subordinated tranches of CLOs. Between the closing date and the effective date of a CLO, the CLO collateral manager will generally expect to purchase additional collateral obligations for the CLO. During this period, the price and availability of these collateral obligations may be adversely affected by a number of market factors, including price volatility and availability of investments suitable for the CLO, which could hamper the ability of the collateral manager to acquire a portfolio of collateral obligations that will satisfy specified concentration limitations and allow the CLO to reach the initial par amount of collateral prior to the effective date. An inability or delay in reaching the target initial par amount of collateral may adversely affect the timing and amount of interest or principal payments received by the holders of the CLO debt securities and distributions of the CLO on equity securities and could result in early redemptions which may cause CLO debt and equity investors to receive less than the face value of their investment. The failure by a CLO in which the Fund invests to satisfy financial covenants, including with respect to adequate collateralization and/or interest coverage tests, could lead to a reduction in the CLO’s payments to the Fund. In the event that a CLO fails certain tests, holders of CLO senior debt may be entitled to additional payments that would, in turn, reduce the payments the Fund would otherwise be entitled to receive. Separately, the Fund may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms, which may include the waiver of certain financial covenants, with a defaulting CLO or any other investment the Fund may make. If any of these occur, it could adversely affect the Fund’s operating results and cash flows. The Fund’s CLO investments are exposed to leveraged credit risk. If certain minimum collateral value ratios and/or interest coverage ratios are not met by a CLO, primarily due to senior secured loan defaults, then cash flow that otherwise would have been available to pay distributions to the Fund on its CLO investments may instead be used to redeem any senior notes or to purchase additional senior secured loans, until the ratios again exceed the minimum required levels or any senior notes are repaid in full. Liquidity Risk The Fund may invest up to 50% of its Managed Assets in securities that are considered illiquid. “Illiquid securities” are securities which cannot be sold within seven days in the ordinary course of business at approximately the value used by the Fund in determining its net asset value. The Fund may not be able to readily dispose of such securities at prices that approximate those at which the Fund could sell such securities if they were more widely-traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Limited liquidity can also affect the market price of securities, thereby adversely affecting the Fund’s net asset value and ability to make dividend distributions. Some Senior Loans are not readily marketable and may be subject to restrictions on resale. Senior Loans are not listed on any national securities exchange and no active trading market may exist for the Senior Loans in which the Fund will invest. Where a secondary market exists, the market for some Senior Loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. The Fund has no limitation on the amount of its assets which may be invested in securities that are not readily marketable or are subject to restrictions on resale. Leverage Risk The Fund currently anticipates utilizing leverage in an aggregate amount of up to 331/3% of its Managed Assets at the time the leverage is incurred in order to buy additional securities. The Fund currently anticipates that it will issue preferred shares and/or notes and it may also borrow funds from banks and other financial institutions. The use of leverage to purchase additional securities creates an opportunity for increased common share dividends, but also creates risks for the holders of common shares. Leverage is a speculative technique that exposes the Fund to greater risk and increased costs than if it were not implemented. Increases and decreases in the value of the Fund’s portfolio will be magnified when the Fund uses leverage. As a result, leverage may cause greater changes in the Fund’s net asset value which will be borne entirely by the Fund’s common shareholders. The Fund will also have to pay dividends on its preferred shares or interest on its notes or borrowings, if any, which will increase expenses and may reduce the Fund’s return. These dividend payments or interest expenses may be greater than the Fund’s return on the underlying investments. The Fund’s leveraging strategy may not be successful. The Fund intends to issue preferred shares and/or notes as a form of leverage. Any such leverage of the Fund would be senior to the Fund’s common shares, such that holders of preferred shares and/or notes would have priority over the common shareholders in the distribution of the Fund’s assets, including dividends, distributions of principal proceeds after the reinvestment period and liquidating distributions. If preferred shares are issued and outstanding, holders of the preferred shares would elect two trustees of the Fund, and would vote separately as a class on certain matters which may at times give holders of preferred shares disproportionate influence over the Fund’s affairs. If the preferred shares were limited in their term, redemptions of such preferred shares would require the Fund to liquidate its investments and would reduce the Fund’s use of leverage, which could negatively impact common shareholders. In addition, the Fund will pay (and the holders of common shares will bear) all costs and expenses relating to the issuance and ongoing maintenance of any preferred shares and/or notes issued by the Fund, including higher advisory fees. Accordingly, the Fund cannot assure you that the issuance of preferred shares and/or notes will result in a higher yield or return to the holders of the common shares. The Fund anticipates that any money borrowed from a bank or other financial institution for investment purposes will accrue interest based on shorter-term interest rates that would be periodically reset. So long as the Fund’s portfolio provides a higher rate of return, net of expenses, than the interest rate on borrowed money, as reset periodically, the leverage may cause the holders of common shares to receive a higher current rate of return than if the Fund were not leveraged. If, however, long-term and/or short-term rates rise, the interest rate on borrowed money could exceed the rate of return on securities held by the Fund, reducing return to the holders of common shares. Recent developments in the credit markets may adversely affect the ability of the Fund to borrow for investment purposes and may increase the costs of such borrowings, which would reduce returns to the holders of common shares. There is no assurance that a leveraging strategy will be successful. Leverage involves risks and special considerations for common shareholders, including:
| ● | the likelihood of greater volatility of net asset value, market price and dividend rate of the common shares than a comparable portfolio without leverage;
| ● | the risk that fluctuations in interest rates on borrowings and short-term debt or in dividend payments on, principal proceeds distributed to, or redemption of any preferred shares and/or notes that the Fund has issued will reduce the return to the common shareholders;
| ● | the effect of leverage in a declining market, which is likely to cause a greater decline in the net asset value of the common shares than if the Fund were not leveraged, which may result in a greater decline in the market price of the common shares;
| ● | when the Fund uses financial leverage, the investment advisory and administrative fees payable to the Adviser and ALPS will be higher than if the Fund did not use leverage, and may provide a financial incentive to the Adviser to increase the Fund’s use of leverage and create an inherent conflict of interest; and
| ● | leverage may increase expenses, which may reduce total return.
If the Fund issues preferred shares and/or notes or borrows money the Fund will be required to maintain asset coverage in conformity with the requirements of the 1940 Act. The Fund may be subject to certain restrictions on investments imposed by guidelines of one or more rating agencies, which may issue ratings for the preferred shares and/or notes or short-term debt securities issued by the Fund. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act. Certain types of borrowings by the Fund may result in the Fund being subject to covenants in credit agreements relating to asset coverage and portfolio composition requirements. These covenants and restrictions may negatively affect the Fund’s ability to achieve its investment objectives. Foreign Currency Risk Because the Fund may invest in securities denominated or quoted in currencies other than the U.S. dollar, changes in foreign currency exchange rates may affect the value of securities in the Fund and the unrealized appreciation or depreciation of investments. Currencies of certain countries may be volatile and therefore may affect the value of securities denominated in such currencies, which means that the Fund’s net asset value could decline as a result of changes in the exchange rates between foreign currencies and the U.S. dollar. The Adviser may, but is not required to, elect for the Fund to seek to protect itself from changes in currency exchange rates through hedging transactions depending on market conditions. The Fund may incur costs in connection with the conversions between various currencies. In addition, certain countries may impose foreign currency exchange controls or other restrictions on the repatriation, transferability or convertibility of currency. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Investment and Market Risk An investment in the Fund’s Common Shares is subject to investment risk, including the possible loss of the entire principal amount invested. An investment in the Fund’s Common Shares represents an indirect investment in the portfolio of floating rate instruments, other securities and derivative investments owned by the Fund, and the value of these investments may fluctuate, sometimes rapidly and unpredictably. At any point in time an investment in the Fund’s Common Shares may be worth less than the original amount invested, even after taking into account distributions paid by the Fund and the ability of common shareholders to reinvest dividends. The Fund may also use leverage, which would magnify the Fund’s investment, market and certain other risks. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Below Investment Grade, or High Yield, Instruments Risk (updated since the prior disclosure date for the Funds) The Fund anticipates that it may invest substantially all of its assets in instruments that are rated below investment grade. Below investment grade instruments are commonly referred to as “junk” or “high yield” instruments and are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal. Lower grade instruments may be particularly susceptible to economic downturns. It is likely that a prolonged or deepening economic downturn could adversely affect the ability of the issuers of such instruments to repay principal and pay interest thereon, increase the incidence of default for such instruments and severely disrupt the market value of such instruments. Below investment grade instruments, though generally higher yielding, are characterized by higher risk. They may be subject to certain risks with respect to the issuing entity and to greater market fluctuations than certain lower yielding, higher rated instruments. The retail secondary market for lower grade instruments may be less liquid than that for higher rated instruments. Adverse conditions could make it difficult at times for the Fund to sell certain instruments or could result in lower prices than those used in calculating the Fund’s NAV. Because of the substantial risks associated with investments in lower grade instruments, investors could lose money on their investment in Common Shares of the Fund, both in the short-term and the long-term.” |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | “Covenant-lite” Obligations Risk The Fund may invest in, or obtain exposure to, obligations that may be “covenant-lite,” which means such obligations lack certain financial maintenance covenants. While these loans may still contain other collateral protections, a covenant-lite loan may carry more risk than a covenant-heavy loan made by the same borrower as it does not require the borrower to provide affirmation that certain specific financial tests have been satisfied on a routine basis as is required under a covenant-heavy loan agreement. Should a loan held by the Fund begin to deteriorate in quality, the Fund’s ability to negotiate with the borrower may be delayed under a covenant-lite loan compared to a loan with full maintenance covenants. This may in turn delay the Fund’s ability to seek to recover its investment. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Valuation Risk Unlike publicly traded common stock which trades on national exchanges, there is no central place or exchange for most of the Fund’s investments to trade. The Fund’s investments generally trade on an “over-the-counter” market which may be anywhere in the world where the buyer and seller can settle on a price. Due to the lack of centralized information and trading, the valuation of loans or fixed-income instruments may carry more risk than that of common stock. Uncertainties in the conditions of the financial market, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. In addition, other market participants may value securities differently than the Fund. As a result, the Fund may be subject to the risk that when an instrument is sold in the market, the amount received by the Fund is less than the value of such instrument carried on the Fund’s books. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  | Swap Risk The Fund may also invest in credit default swaps, total return swaps and interest rate swaps. Such transactions are subject to market risk, liquidity risk, risk of default by the other party to the transaction, known as “counterparty risk,” and risk of imperfect correlation between the value of such instruments and the underlying assets and may involve commissions or other costs. When buying protection under a swap, the risk of loss with respect to swaps generally is limited to the net amount of payments that the Fund is contractually obligated to make. However, when selling protection under a swap, the risk of loss is often the notional value of the underlying asset, which can result in a loss substantially greater than the amount invested in the swap itself. The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid; however, there is no guarantee that the swap market will continue to provide liquidity. If the Adviser is incorrect in its forecasts of market values, interest rates or currency exchange rates, the investment performance of the Fund would be less favorable than it would have been if these investment techniques were not used. In a total return swap, the Fund pays the counterparty a floating short-term interest rate and receives in exchange the total return of underlying loans or debt securities (or pays an equivalent amount, if the total return is negative). The Fund bears the risk of default on the underlying loans or debt securities, based on the notional amount of the swap. The Fund would typically have to post collateral to cover potential obligations under the swap. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Credit Risk Credit risk is the risk that one or more Loans or other instruments in the Fund’s portfolio will decline in price or fail to pay interest or principal when due because the issuer of the instrument experiences a decline in its financial status. While a senior position in the capital structure of a Borrower or issuer may provide some protection with respect to the Fund’s investments in certain Loans, losses may still occur because the market value of Loans is affected by the creditworthiness of Borrowers or issuers and by general economic and specific industry conditions and the Fund’s other investments will often be subordinate to other debt in the issuer’s capital structure. To the extent the Fund invests in below investment grade instruments, it will be exposed to a greater amount of credit risk than a fund which invests in investment grade securities. The prices of lower grade instruments are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade instruments. Instruments of below investment grade quality are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due and therefore involve a greater risk of default. In addition, the Fund may enter into credit derivatives which may expose it to additional risk in the event that the instruments underlying the derivatives default. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Interest Rate Risk The fixed-income instruments that the Fund may invest in are subject to the risk that market values of such securities will decline as interest rates increase. These changes in interest rates have a more pronounced effect on securities with longer durations. Typically, the impact of changes in interest rates on the market value of an instrument will be more pronounced for fixed-rate instruments, such as most corporate bonds, than it will for Loans or other floating rate instruments. Fluctuations in the value of portfolio securities will not affect interest income on existing portfolio securities but will be reflected in the Fund’s NAV. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Systematic Strategies Related To Bond Investments Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Systematic Strategies Related to Bond Investments Risk With respect to the bond portion of the Fund’s portfolio, to the extent to which the proprietary model used by the Adviser (the "Model") or comparable methods or strategies are employed, certain of the Adviser’s securities analysis methods will rely on the assumption that the companies whose securities are purchased or sold, the rating agencies that review these securities, and other publicly available sources of information about these securities, are providing accurate and unbiased data. While the Adviser is alert to indications that data may be incorrect, there is always a risk that the Adviser’s analysis may be compromised by inaccurate or misleading information. The Model the Adviser intends to utilize to manage the Fund’s bond investments could lead to unsatisfactory investments. The Adviser might not be able to effectively implement the Model, and there can be no guarantee that the Fund will achieve the desired results. Certain aspects of the Adviser’s investment process with respect to the Model are dependent on complex proprietary software, which requires constant development and refinement. The Adviser has implemented procedures designed to appropriately control the development and implementation of the Model. However, analytical, coding and implementation errors present substantial risks to complex models and quantitative investment management strategies. The Adviser cannot guarantee that its internal controls will be effective in all circumstances. The Fund could be negatively affected by undetected software defects or fundamental issues with the Adviser’s method of interpreting and acting upon the Model’s output. The Adviser’s implementation of its investment strategy with respect to the Fund’s bond portfolio utilizing the Model will rely on the analytical and mathematical foundation of the Model and the incorporation of the Model’s outputs into a complex computational environment. Any such strategy is also dependent on the quality of the market data utilized by the Model, changes in credit market conditions, creation and maintenance of the Model’s software and the successful incorporation of the Model’s output into the construction of the Fund’s bond portfolio. There is always a possibility of human error in the creation, maintenance and use of the Model. Moreover, the Adviser’s portfolio managers exercise discretion in the utilization of the Model, and the investment results of the relevant portion(s) of the Fund’s investments are dependent on the ability of portfolio managers to correctly understand and implement or disregard the Model’s signals. There can be no assurance that utilizing the Model will yield better results than any other investment method. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | LIBOR Risk (updated since the prior disclosure date for the Funds) The United Kingdom’s Financial Conduct Authority announced a phase out of the LIBOR in 2017. Although many LIBOR rates ceased to be published or no longer are representative of the underlying market they seek to measure after December 31, 2021, a selection of widely used U.S. dollar LIBOR rates will continue to be published through June 2023 in order to assist with the transition. Further, on March 15, 2022, the Consolidated Appropriations Act of 2022, which includes the Adjustable Interest Rate (LIBOR) Act, was signed into law in the United States. This legislation establishes a uniform benchmark replacement process for financial contracts that mature after June 30, 2023 that do not contain clearly defined or practicable fallback provisions. The FRS, in conjunction with the ARRC, a steering committee comprised of large U.S. financial institutions, has begun publishing SOFR, which is their preferred alternative rate for U.S. dollar LIBOR, and which is a new index calculated by short-term repurchase agreements, backed by Treasury securities. Proposals for alternative reference rates for other currencies have also been announced or have already begun publication. Markets are in the process of developing in response to these new rates. Although financial regulators and industry working groups have suggested alternative reference rates, such as the European Interbank Offer Rate, the Sterling Overnight Interbank Average Rate and SOFR, there has been no global consensus as to an alternative rate and the process for amending existing contracts or instruments to transition away from LIBOR remains incomplete. Given the inherent differences between LIBOR and SOFR, or any other alternative benchmark rate that may be established, there remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate. In many cases, the nominated replacements, as well as other potential replacements, are not complete or ready to implement and require margin adjustments. There is currently no final consensus as to which benchmark rate(s) (along with any adjustment and/or permutation thereof) will replace all or any LIBOR tenors (i.e., the maturity period) after the discontinuation thereof and there can be no assurance that any such replacement benchmark rate(s) will attain market acceptance. Before LIBOR ceases to exist, the Fund and its underlying obligors may need to amend or restructure existing LIBOR-based debt instruments and any related hedging arrangements that extend beyond June 30, 2023, depending on the applicable LIBOR tenor. Such amendments and restructurings may be difficult, costly and time consuming. In addition, from time to time the Fund invests in floating rate loans and investment securities whose interest rates are indexed to LIBOR. Uncertainty as to the nature of alternative reference rates and as to potential changes or other reforms to LIBOR, or any changes announced with respect to such reforms, may result in a sudden or prolonged increase or decrease in the reported LIBOR rates and the value of LIBOR-based loans and securities, including those of other issuers the Fund currently owns or may in the future own. It remains uncertain how such changes would be implemented and the effects such changes would have on the Fund, issuers of instruments in which the Fund invests and financial markets generally. The expected discontinuation of LIBOR could have a significant impact on our business. There could be significant operational challenges for the transition away from LIBOR including, but not limited to, amending loan agreements with borrowers on investments that may have not been modified with fallback language and adding effective fallback language to new agreements in the event that LIBOR is discontinued before maturity. Beyond these challenges, we anticipate there may be additional risks to our current processes and information systems that will need to be identified and evaluated by us. Due to the uncertainty of the replacement for LIBOR, the potential effect of any such event on our cost of capital and net investment income cannot yet be determined. In addition, the cessation of LIBOR could:
| ● | Adversely impact the pricing, liquidity, value of, return on and trading for a broad array of financial products, including any LIBOR-linked securities, loans and derivatives that may be included in our assets and liabilities;
| ● | Require extensive changes to documentation that governs or references LIBOR or LIBOR-based products, including, for example, pursuant to time-consuming renegotiations of documentation to modify the terms of investments;
| ● | Result in inquiries or other actions from regulators in respect of our preparation and readiness for the replacement of LIBOR with one or more alternative reference rates;
| ● | Result in disputes, litigation or other actions with portfolio companies, or other counterparties, regarding the interpretation and enforceability of provisions in our LIBOR-based investments, such as fallback language or other related provisions, including, in the case of fallbacks to the alternative reference rates, any economic, legal, operational or other impact resulting from the fundamental differences between LIBOR and the various alternative reference rates;
| ● | Require the transition and/or development of appropriate systems and analytics to effectively transition our risk management processes from LIBOR-based products to those based on one or more alternative reference rates, which may prove challenging given the limited history of the proposed alternative reference rates; and
| ● | Cause us to incur additional costs in relation to any of the above factors.
There is no guarantee that a transition from LIBOR to an alternative will not result in financial market disruptions, significant increases in benchmark rates, or borrowing costs to borrowers, any of which could have a material adverse effect on our business, result of operations, financial condition, and Common Share price. In addition, the transition to a successor rate could potentially cause (i) increased volatility or illiquidity in markets for instruments that currently rely on LIBOR, (ii) a reduction in the value of certain instruments held by the Fund, or (iii) reduced effectiveness of related Fund transactions, such as hedging. It remains uncertain how such changes would be implemented and the effects such changes would have on the Fund, issuers of instruments in which the Fund invests and financial markets generally. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Force Majeure Risk The Fund may be affected by force majeure events (e.g., acts of God, fire, flood, earthquakes, outbreaks of an infectious disease, pandemic or any other serious public health concern, war, terrorism, nationalization of industry and labor strikes). Force majeure events could adversely affect the ability of the Fund or a counterparty to perform its obligations. The liability and cost arising out of a failure to perform obligations as a result of a force majeure event could be considerable and could be borne by the Fund. Certain force majeure events, such as war or an outbreak of an infectious disease, could have a broader negative impact on the global or local economy, thereby affecting the Fund. Additionally, a major governmental intervention into industry, including the nationalization of an industry or the assertion of control, could result in a loss to the Fund if an investment is affected, and any compensation provided by the relevant government may not be adequate. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Epidemic and Pandemic Risk The world has been susceptible to epidemics/pandemics, most recently COVID-19, which has been designated as a pandemic by the World Health Organization. Any outbreak of COVID-19, SARS, H1N1/09 flu, avian flu, other coronavirus, Ebola or other existing or new epidemics/pandemics, or the threat thereof, together with any resulting restrictions on travel or quarantines imposed, has had, and will continue to have, an adverse impact on the economy and business activity globally (including in the countries in which the Fund invests), and thereby is expected to adversely affect the performance of the Fund’s investments and the Fund’s ability to fulfill its investment objectives. Furthermore, the rapid development of epidemics/pandemics could preclude prediction as to their ultimate adverse impact on economic and market conditions, and, as a result, presents material uncertainty and risk with respect to the Fund and the performance of its investments. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Market Disruption and Geopolitical Risk (updated since the prior disclosure date for the Funds) The Fund may be adversely affected by uncertainties such as terrorism, international political developments, and changes in government policies, taxation, restrictions on foreign investment and currency repatriation, currency fluctuations and other developments in the laws and regulations of the countries in which it is invested. Likewise, natural and environmental disasters, epidemics or pandemics, and systemic market dislocations may be highly disruptive to economies and markets. See “—Epidemic and Pandemic Risk” above. Uncertainties and events around the world may (i) result in market volatility, (ii) have long-term effects on the U.S. and worldwide financial markets and (iii) cause further economic uncertainties in the United States and worldwide. The Fund cannot predict the effects of geopolitical events in the future on the U.S. economy and securities markets. Additionally, certain of the Funds’ investments may operate in, or have dealings with, countries subject to sanctions or embargos imposed by the U.S. government, foreign governments, or the United Nations or other international organizations. For example, the ongoing conflict due to Russia’s invasion of Ukraine and the rapidly evolving measures in response could be expected to have a negative impact on the economy and business activity globally (including in the countries in which the Funds invest). The severity and duration of the conflict and its impact on global economic and market conditions are impossible to predict, and as a result, present material uncertainty and risk with respect to the Funds and their investments and operations, and the ability of the Funds to achieve their investment objectives. Sanctions could also result in Russia taking counter measures or retaliatory actions which could adversely impact the Funds' business or the business of the Funds' investments, including, but not limited to, cyberattacks targeting private companies, individuals or other infrastructure upon which the Funds' business and the business of the Funds' portfolio companies or obligors rely. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Lender Liability Risk A number of U.S. judicial decisions have upheld judgments obtained by Borrowers against lending institutions on the basis of various evolving legal theories, collectively termed “lender liability.” Generally, lender liability is founded on the premise that a lender has violated a duty (whether implied or contractual) of good faith, commercial reasonableness and fair dealing, or a similar duty owed to the Borrower or has assumed an excessive degree of control over the Borrower resulting in the creation of a fiduciary duty owed to the Borrower or its other creditors or shareholders. Because of the nature of its investments, the Fund may be subject to allegations of lender liability. In addition, under common law principles that in some cases form the basis for lender liability claims, if a lender or bondholder (a) intentionally takes an action that results in the undercapitalization of a Borrower to the detriment of other creditors of such Borrower, (b) engages in other inequitable conduct to the detriment of such other creditors, (c) engages in fraud with respect to, or makes misrepresentations to, such other creditors or (d) uses its influence as a stockholder to dominate or control a Borrower to the detriment of other creditors of such Borrower, a court may elect to subordinate the claim of the offending lender or bondholder to the claims of the disadvantaged creditor or creditors, a remedy called “equitable subordination.” Because affiliates of, or persons related to, the Adviser may hold equity or other interests in obligors of the Fund, the Fund could be exposed to claims for equitable subordination or lender liability or both based on such equity or other holdings. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  | Counterparty Risk The Fund is subject to credit risk with respect to the counterparties to its derivatives contracts (whether a clearing corporation in the case of exchange-traded instruments or our hedge counterparty in the case of OTC instruments) purchased by the Fund. Counterparty risk is the risk that the other party in a derivative transaction will not fulfill its contractual obligation. Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to their derivative transactions will affect the value of those instruments. By entering into derivatives, the Fund assumes the risks that theses counterparties could experience financial or other hardships that could call into question their continued ability to perform their obligations. In the case of a default by the counterparty, the Fund could become subject to adverse market movements while replacement transactions are executed. The ability of the Fund to transact business with any one or number of counterparties, the possible lack of a meaningful and independent evaluation of such counterparties’ financial capabilities, and the absence of a regulated market to facilitate settlement may increase the potential for losses by the Fund. Furthermore, concentration of derivatives in any particular counterparty would subject the Fund to an additional degree of risk with respect to defaults by such counterparty. The Adviser evaluates and monitors the creditworthiness of counterparties in order to ensure that such counterparties can perform their obligations under the relevant agreements. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial or other difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a dissolution, assignment for the benefit of creditors, liquidation, winding-up, bankruptcy or other analogous proceedings. In addition, in the event of the insolvency of a counterparty to a derivative transaction, the derivative contract would typically be terminated at its fair market value. If the Fund is owed this fair market value upon the termination of the derivative contract and its claim is unsecured, the Fund will be treated as a general creditor of such counterparty, and will not have any claim with respect to the underlying assets. The Fund may obtain only a limited recovery or may obtain no recovery at all in such circumstances. In addition, regulations that were adopted by prudential regulators in 2019 require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many derivatives contracts, terms that delay or restrict the rights of counterparties, such as the Fund, to terminate such contracts, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that such counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. Certain categories of interest rate and credit default swaps are subject to mandatory clearing, and more categories may be subject to mandatory clearing in the future. The counterparty risk for cleared derivatives is generally lower than for uncleared OTC derivative transactions because generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing house for performance of financial obligations. However, there can be no assurance that a clearing house, or its members, will satisfy the clearing house’s obligations (including, but not limited to, financial obligations and legal obligations to segregate margins collected by the clearing house) to the Fund. Counterparty risk with respect to certain exchange-traded and over-the-counter derivatives may be further complicated by recently enacted U.S. financial reform legislation. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Potential Conflicts Of Interest Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  | Potential Conflicts of Interest Risk The Adviser will be subject to certain conflicts of interest in its management of the Fund. These conflicts will arise primarily from the involvement of the Adviser, Blackstone Alternative Credit Advisors LP (“Blackstone Credit”), Blackstone Inc. (“Blackstone”) and their affiliates in other activities that may conflict with those of the Fund. The Adviser, Blackstone Credit, Blackstone and their affiliates engage in a broad spectrum of activities. In the ordinary course of their business activities, the Adviser, Blackstone Credit, Blackstone and their affiliates may engage in activities where the interests of certain divisions of the Adviser, Blackstone Credit, Blackstone and their affiliates or the interests of their clients may conflict with the interests of the Fund or the common shareholders. Other present and future activities of the Adviser, Blackstone Credit, Blackstone and their affiliates may give rise to additional conflicts of interest, which may have a negative impact on the Fund. In addressing these conflicts and regulatory, legal and contractual requirements across its various businesses, Blackstone has implemented certain policies and procedures (e.g., information walls) that may reduce the positive firm-wide synergies that the Adviser may have potentially utilized for purposes of finding attractive investments. Additionally, Blackstone may limit a client and/or its portfolio companies from engaging in agreements with or related to companies in which any fund of Blackstone has or has considered making an investment or which is otherwise an advisory client of Blackstone and/or from time to time restrict or otherwise limit the ability of the Fund to make investments in or otherwise engage in businesses or activities competitive with companies or other clients of Blackstone, either as result of contractual restrictions or otherwise. Finally, Blackstone has in the past entered, and is likely in the future to enter, into one or more strategic relationships in certain regions or with respect to certain types of investments that, although possibly intended to provide greater opportunities for the Fund, may require the Fund to share such opportunities or otherwise limit the amount of an opportunity the Fund can otherwise take. As part of its regular business, Blackstone provides a broad range of services other than those provided by the Adviser, including investment banking, underwriting, capital markets syndication and advisory (including underwriting), placement, financial advisory, restructuring and advisory, consulting, asset/property management, mortgage servicing, insurance (including title insurance), monitoring, commitment, syndication, origination, servicing, management consulting and other similar operational and finance matters, healthcare consulting/brokerage, group purchasing, organizational, operational, loan servicing, financing, divestment and other services. In addition, Blackstone may provide services in the future beyond those currently provided. The Fund will not receive a benefit from the fees or profits derived from such services. In such a case, a client of Blackstone would typically require Blackstone to act exclusively on its behalf. This request may preclude all of Blackstone clients (including the Fund) from participating in related transactions that would otherwise be suitable. Blackstone will be under no obligation to decline any such engagements in order to make an investment opportunity available to the Fund. In connection with its other businesses, Blackstone will likely come into possession of information that limits its ability to engage in potential transactions. The Fund’s activities are expected to be constrained as a result of the inability of the personnel of Blackstone to use such information. For example, employees of Blackstone from time to time are prohibited by law or contract from sharing information with members of the Adviser’s investment team that would be relevant to monitoring the Fund’s portfolio and other investment decisions. Additionally, there are expected to be circumstances in which one or more of certain individuals associated with Blackstone will be precluded from providing services related to the Fund’s activities because of certain confidential information available to those individuals or to other parts of Blackstone (e.g., trading may be restricted). Blackstone has long term relationships with a significant number of corporations and their senior management. In determining whether to invest in a particular transaction on behalf of the Fund, the Adviser will consider those relationships, and may decline to participate in a transaction as a result of such relationships. To the extent permitted by the 1940 Act, the Fund may also co-invest with clients of Blackstone in particular investment opportunities, and the relationship with such clients could influence the decisions made by the Adviser with respect to such investments. The Fund may be forced to sell or hold existing investments (possibly at disadvantageous times or under disadvantageous conditions) as a result of various relationships that Blackstone may have or transactions or investments Blackstone and its affiliates may make or have made. The inability to transact in any security, derivative or loan held by the Fund could result in significant losses or lost opportunity costs to the Fund. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Limitations on Transactions with Affiliates Risk The 1940 Act limits our ability to enter into certain transactions with certain of our affiliates. As a result of these restrictions, we may be prohibited from buying or selling any security directly from or to any portfolio company of or private equity fund managed by Blackstone, Blackstone Credit or any of their respective affiliates. However, the Fund may under certain circumstances purchase any such portfolio company’s loans or securities in the secondary market, which could create a conflict for the Adviser between the interests of the Fund and the portfolio company, in that the ability of the Adviser to recommend actions in the best interest of the Fund might be impaired. The 1940 Act also prohibits certain “joint” transactions with certain of our affiliates, which could include investments in the same portfolio company (whether at the same or different times). These limitations may limit the scope of investment opportunities that would otherwise be available to us. Although the Fund has received an exemptive order from the SEC that permits it, among other things, to co-invest with certain affiliates of the Adviser and certain funds managed and controlled by the Adviser and its affiliates, it may only do so in accordance with certain terms and conditions that limit the types of transactions the Fund may engage in. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Dependence on Key Personnel Risk The Adviser is dependent upon the experience and expertise of certain key personnel in providing services with respect to the Fund’s investments. If the Adviser were to lose the services of these individuals, its ability to service the Fund could be adversely affected. As with any managed fund, the Adviser may not be successful in selecting the best-performing securities or investment techniques for the Fund’s portfolio and the Fund’s performance may lag behind that of similar funds. The Adviser has informed the Fund that the investment professionals associated with the Adviser are actively involved in other investment activities not concerning the Fund and will not be able to devote all of their time to the Fund’s business and affairs. In addition, individuals not currently associated with the Adviser may become associated with the Fund and the performance of the Fund may also depend on the experience and expertise of such individuals. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Prepayment Risk During periods of declining interest rates, Borrowers or issuers may exercise their option to prepay principal earlier than scheduled. For fixed rate securities, such payments often occur during periods of declining interest rates, forcing the Fund to reinvest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions to common shareholders. This is known as prepayment or “call” risk. Below investment grade instruments frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met (“call protection”). An issuer may redeem a below investment grade instrument if, for example, the issuer can refinance the debt at a lower cost due to declining interest rates or an improvement in the credit standing of the issuer. Loans and the loans underlying CLOs in which the Fund invests typically do not have call protection after a certain period from initial issuance. For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be enhanced. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | UK Exit from the EU The UK formally left the EU on January 31, 2020 (commonly known as “Brexit”), subject to a transition period that ended on December 31, 2020. During an 11-month transition period, the United Kingdom, including its businesses and people, abided by applicable EU rules, honored the United Kingdom’s trade relationships with EU countries, and prepared for the new post-Brexit rules which took effect on January 1, 2021. Since the June 2016 referendum in the UK, global financial markets have experienced significant volatility due to the uncertainty around Brexit. There will likely continue to be considerable uncertainty as to the longer term economic, legal, political and social framework to be put in place between the UK and the EU, in particular as to the arrangements which will apply to its relationships with the EU and with other countries. This process and/or the uncertainty associated with it may adversely affect the return on investments economically tied to the UK (and consequently the Fund). This may be due to, among other things: (i) increased uncertainty and volatility in UK, EU and other financial markets; (ii) fluctuations in asset values; (iii) fluctuations in exchange rates; (iv) increased illiquidity of investments located, listed or traded within the UK, the EU or elsewhere; (v) changes in the willingness or ability of financial and other counterparties to enter into transactions, or the price at which and terms on which they are prepared to transact; and/or (vi) changes in legal and regulatory regimes to which the Fund’s investments are or become subject. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Repurchase Agreements Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  | Repurchase Agreements Risk Subject to its investment objectives and policies, the Fund may invest in repurchase agreements as a buyer for investment purposes. Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. The Fund does not bear the risk of a decline in the value of the underlying security unless the seller defaults under its repurchase obligation. In the event of the bankruptcy or other default of a seller of a repurchase agreement, the Fund could experience both delays in liquidating the underlying securities and losses, including (1) possible decline in the value of the underlying security during the period in which the Fund seeks to enforce its rights thereto; (2) possible lack of access to income on the underlying security during this period; and (3) expenses of enforcing its rights. In addition, as described above, the value of the collateral underlying the repurchase agreement will be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, the Fund generally will seek to liquidate such collateral. However, the exercise of the Fund’s right to liquidate such collateral could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Fund could suffer a loss. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Reverse Repurchase Agreements Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Reverse Repurchase Agreements Risk The Fund’s use of reverse repurchase agreements involves many of the same risks involved in the Fund’s use of leverage, as the proceeds from reverse repurchase agreements generally will be invested in additional securities. There is a risk that the market value of the securities acquired in the reverse repurchase agreement may decline below the price of the securities that the Fund has sold but remains obligated to repurchase. In addition, there is a risk that the market value of the securities retained by the Fund may decline. If the buyer of securities under a reverse repurchase agreement were to file for bankruptcy or experiences insolvency, the Fund may be adversely affected. Also, in entering into reverse repurchase agreements, the Fund would bear the risk of loss to the extent that the proceeds of the reverse repurchase agreement are less than the value of the underlying securities. In addition, due to the interest costs associated with reverse repurchase agreements transactions, the Fund’s NAV will decline, and, in some cases, the Fund may be worse off than if it had not used such instruments. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Investments In Equity Securities Or Warrants Incidental To Investments In Fixed Income Instruments [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Investments in Equity Securities or Warrants Incidental to Investments in Fixed Income Instruments From time to time the Fund also may invest in or hold common stock and other equity securities or warrants incidental to the purchase or ownership of a fixed income instrument or in connection with a reorganization of an issuer. Investments in equity securities incidental to investments in fixed income instruments entail certain risks in addition to those associated with investments in fixed income instruments. Because equity is merely the residual value of an issuer after all claims and other interests, it is inherently more risky than the bonds or loans of the same issuer. The value of the equity securities may be affected more rapidly, and to a greater extent, by company-specific developments and general market conditions. These risks may increase fluctuations in the Fund's NAV. The Fund frequently may possess material non-public information about a Borrower or issuer as a result of its ownership of a fixed income instrument. Because of prohibitions on trading in securities while in possession of material non-public information, the Fund might be unable to enter into a transaction in a security of an issuer when it would otherwise be advantageous to do so. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Inflation Deflation Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Inflation/Deflation Risk Inflation risk is the risk that the value of certain assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Shares and Preferred Shares, and distributions thereon, can decline. In addition, during any periods of rising inflation, the dividend rates or borrowing costs associated with the Fund’s use of leverage would likely increase, which would tend to further reduce returns to common shareholders. Deflation risk is the risk that prices throughout the economy decline over time—the opposite of inflation. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer defaults more likely, which may result in a decline in the value of the Fund’s portfolio. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
U S Government Debt Securities Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  | U.S. Government Debt Securities Risk U.S. government debt securities generally do not involve the credit risks associated with investments in other types of debt securities, although, as a result, the yields available from U.S. government debt securities are generally lower than the yields available from other securities. Like other debt securities, however, the values of U.S. government securities change as interest rates fluctuate. Fluctuations in the value of portfolio securities will not affect interest income on existing portfolio securities but will be reflected in the Fund’s NAV. Since the magnitude of these fluctuations will generally be greater at times when the Fund’s average maturity is longer, under certain market conditions the Fund may, for temporary defensive purposes, accept lower current income from short-term investments rather than investing in higher yielding long-term securities. In addition, the recent economic crisis in the United States has negatively impacted government-sponsored entities, which include Federal Home Loan Banks, Fannie Mae and Freddie Mac. As the real estate market has deteriorated through declining home prices and increasing foreclosure, government-sponsored entities, which back the majority of U.S mortgages, have experienced extreme volatility and in some cases a lack of liquidity. In September 2008, Fannie Mae and Freddie Mac were placed under a conservatorship of the U.S. federal government. Any Fund investments issued by Federal Home Loan Banks and Fannie Mae may ultimately lose value. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Cyber Security Risk And Identity Theft Risks [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  | Cyber-Security Risk and Identity Theft Risks The Fund’s operations are highly dependent on the Adviser’s information systems and technology and the Fund relies heavily on the Adviser’s financial, accounting, communications and other data processing systems. The Adviser’s systems may fail to operate properly or become disabled as a result of tampering or a breach of its network security systems or otherwise. In addition, the Adviser’s systems face ongoing cybersecurity threats and attacks. Attacks on the Adviser’s systems could involve, and in some instances have in the past involved, attempts intended to obtain unauthorized access to its proprietary information, destroy data or disable, degrade or sabotage its systems, or divert or otherwise steal funds, including through the introduction of computer viruses, “phishing” attempts and other forms of social engineering. Cyberattacks and other security threats could originate from a wide variety of external sources, including cyber criminals, nation state hackers, hacktivists and other outside parties. Cyberattacks and other security threats could also originate from the malicious or accidental acts of insiders, such as employees of the Adviser. There has been an increase in the frequency and sophistication of the cyber and security threats the Adviser faces, with attacks ranging from those common to businesses to those that are more advanced and persistent, which may target the Adviser because, as an alternative asset management firm, the Adviser holds a significant amount of confidential and sensitive information about its investors, its portfolio companies or obligors (as applicable) and potential investments. As a result, the Adviser may face a heightened risk of a security breach or disruption with respect to this information. There can be no assurance that measures the Adviser takes to ensure the integrity of its systems will provide protection, especially because cyberattack techniques used change frequently or are not recognized until successful. If the Adviser’s systems are compromised, do not operate properly or are disabled, or it fails to provide the appropriate regulatory or other notifications in a timely manner, the Adviser could suffer financial loss, a disruption of its businesses, liability to its investment funds and fund investors, including the Fund and common shareholders, regulatory intervention or reputational damage. The costs related to cyber or other security threats or disruptions may not be fully insured or indemnified by other means. In addition, the Fund could also suffer losses in connection with updates to, or the failure to timely update, the Adviser’s information systems and technology. In addition, the Adviser has become increasingly reliant on third party service providers for certain aspects of its business, including for the administration of certain funds, as well as for certain information systems and technology, including cloud-based services. These third party service providers could also face ongoing cyber security threats and compromises of their systems and as a result, unauthorized individuals could gain, and in some past instances have gained, access to certain confidential data. Cybersecurity has become a top priority for regulators around the world. Many jurisdictions in which the Adviser operates have laws and regulations relating to data privacy, cybersecurity and protection of personal information, including, as examples, the General Data Protection Regulation in the EU and that went into effect in May 2018 and the California Consumer Privacy Act that went into effect in January 2020. Some jurisdictions have also enacted laws requiring companies to notify individuals and government agencies of data security breaches involving certain types of personal data. Breaches in security, whether malicious in nature or through inadvertent transmittal or other loss of data, could potentially jeopardize the Adviser, its employees’ or the Fund’s investors’ or counterparties’ confidential, proprietary and other information processed and stored in, and transmitted through, the Adviser’s computer systems and networks, or otherwise cause interruptions or malfunctions in its, its employees’, the Fund’s investors’, the Fund’s counterparties’ or third parties’ business and operations, which could result in significant financial losses, increased costs, liability to the Fund’s investors and other counterparties, regulatory intervention and reputational damage. Furthermore, if the Adviser fails to comply with the relevant laws and regulations or fail to provide the appropriate regulatory or other notifications of breach in a timely matter, it could result in regulatory investigations and penalties, which could lead to negative publicity and reputational harm, and may cause the Fund’s investors and clients to lose confidence in the effectiveness of its security measures. Obligors of the Fund also rely on data processing systems and the secure processing, storage and transmission of information, including payment and health information. A disruption or compromise of these systems could have a material adverse effect on the value of these businesses. The Fund may invest in strategic assets having a national or regional profile or in infrastructure, the nature of which could expose it to a greater risk of being subject to a terrorist attack or security breach than other assets or businesses. Such an event may have material adverse consequences on the Fund’s investment or assets of the same type or may require obligors of the Fund to increase preventative security measures or expand insurance coverage. Finally, the Adviser’s and the Fund’s technology, data and intellectual property and the technology, data and intellectual property of their portfolio companies or obligors (as applicable) are also subject to a heightened risk of theft or compromise to the extent the Adviser and the Fund’s portfolio companies or obligors (as applicable) engage in operations outside the United States, in particular in those jurisdictions that do not have comparable levels of protection of proprietary information and assets such as intellectual property, trademarks, trade secrets, know-how and customer information and records. In addition, the Adviser and the Fund and their portfolio companies or obligors (as applicable) may be required to compromise protections or forego rights to technology, data and intellectual property in order to operate in or access markets in a foreign jurisdiction. Any such direct or indirect compromise of these assets could have a material adverse impact on the Adviser and the Fund and their portfolio companies or obligors (as applicable). |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Portfolio Turnover Risk The Fund’s annual portfolio turnover rate may vary greatly from year to year, as well as within a given year. However, portfolio turnover rate is not considered a limiting factor in the execution of investment decisions for the Fund. High portfolio turnover may result in the realization of net short-term capital gains by the Fund which, when distributed to common shareholders, will be taxable as ordinary income. A high portfolio turnover may increase the Fund’s current and accumulated earnings and profits, resulting in a greater portion of the Fund’s distributions being treated as a dividend to the Fund’s common shareholders. In addition, a higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Government Intervention in the Financial Markets The recent instability in the financial markets has led the U.S. government to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility, and in some cases a lack of liquidity. Federal, state, and other governments, their regulatory agencies or self-regulatory organizations may take additional actions that affect the regulation of the securities or structured products in which the Fund invests, or the issuers of such securities or structured products, in ways that are unforeseeable. Borrowers under Secured Loans held by the Fund may seek protection under the bankruptcy laws. Legislation or regulation may also change the way in which the Fund itself is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objectives. The Adviser will monitor developments and seek to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objectives, but there can be no assurance that it will be successful in doing so. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Inflation and Supply Chain Risk (updated since the prior disclosure date for the Funds) Economic activity has continued to accelerate across sectors and regions. Nevertheless, due to global supply chain issues, a rise in energy prices and strong consumer demand as economies continue to reopen, inflation has increased in the U.S. and globally. Inflation is likely to continue in the near to medium-term, particularly in the U.S., with the possibility that monetary policy may continue to tighten in response. There can be no assurance that inflation will not become a serious problem in the future and have an adverse impact on the Fund’s returns. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Derivatives Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  | Derivatives Risk (updated since the Fund’s prior disclosure date) Under normal market conditions, the use of derivatives by the Fund, other than for hedging purposes, will not exceed 20% of the Fund’s Managed Assets on a mark-to-market basis. The Fund’s use of derivative instruments may be speculative and involves investment risks and transaction costs to which the Fund would not be subject absent the use of these instruments, and the use of derivatives generally involves leverage in the sense that the investment exposure created by the derivatives may be significantly greater than the Fund’s initial investment in the derivatives. In some cases, the use of derivatives may result in losses in excess of principal or greater than if they had not been used. The ability to successfully use derivative instruments depends on the ability of the Adviser. The skills needed to employ derivatives strategies are different from those needed to select a portfolio security and, in connection with such strategies, the Adviser must make predictions with respect to market conditions, liquidity, currency movements, market values, interest rates and other applicable factors, which may be inaccurate. The use of derivative instruments may require the Fund to sell or purchase portfolio securities at inopportune times or for prices below or above the current market values, may limit the amount of appreciation the Fund can realize on an investment or may cause the Fund to hold a security that it might otherwise want to sell. The Fund may also have to defer closing out certain derivative positions to avoid adverse tax consequences and there may be situations in which derivative instruments are not elected that result in losses greater than if such instruments had been used. Amounts paid by the Fund as premiums and cash or other assets held in margin accounts with respect to the Fund’s derivative instruments would not be available to the Fund for other investment purposes, which may result in lost opportunities for gain. Changes to the derivatives markets as a result of the continuous promulgation of rules under the Dodd-Frank Act and other government or international and other government regulation may also have an adverse effect on the Fund’s ability to make use of derivative transactions. In addition, the use of derivatives is subject to other risks, each of which may create additional risk of loss, including liquidity risk, interest rate risk, credit risk and management risk as well as the following risks:
| ● | Correlation Risk. Imperfect correlation between the value of derivative instruments and the underlying assets of the Fund creates the possibility that the loss on such instruments may be greater than the gain in the value of the underlying assets in the Fund’s portfolio.
| ● | Duration Mismatch Risk. The duration of a derivative instrument may be significantly different than the duration of the related liability or asset.
| ● | Valuation Risk. The prices of derivative instruments, including swaps, futures, forwards and options, could be highly volatile and such instruments may subject us to significant losses. The value of such derivatives also depends upon the price of the underlying asset, reference rate or index, which may also be subject to volatility. In addition, actual or implied daily limits on price fluctuations and speculative position limits on the exchanges or over-the-counter markets in which we may conduct our transactions in derivative instruments may prevent prompt liquidation of positions, subjecting us to the potential of greater losses. In addition, significant disparities may exist between “bid” and “asked” prices for derivative instruments that are traded over-the-counter and not on an exchange.
| ● | Liquidity Risk. Derivative instruments, especially when purchased in large amounts, may not be liquid in all circumstances, so that in volatile markets we may not be able to close out a position without incurring a loss.
| ● | Counterparty Risk. Derivative instruments also involve exposure to counterparty risk, since contract performance depends in part on the financial condition of the counterparty.
In addition, the Adviser may cause the Fund to invest in derivative instruments that are neither presently contemplated nor currently available, but which may be developed in the future, to the extent such opportunities are both consistent with the Fund’s investment objectives and legally permissible. Any such investments may expose the Fund to unique and presently indeterminate risks, the impact of which may not be capable of determination until such instruments are developed and/or the Adviser determines to make such an investment on behalf of the Fund. Rule 18f-4 requires registered investment companies to adopt a written policies and procedures reasonably designed to manage the Fund’s derivatives risks. In the event that the Fund’s derivatives exposure exceeds 10% of its net assets, the Fund will be required to adopt a written derivatives risk management program and comply with a value-at-risk based limit on leverage risk. The Board of Trustees has an oversight role in ensuring these new requirements are being taken into account and, if required, will appoint a derivatives risk manager to handle the day-to-day responsibilities of the derivatives risk management program. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Senior Loans Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  | Senior Loans Risk Under normal market conditions, the Fund will invest at least 80% of its Managed Assets in Senior Loans. This policy is not fundamental and may be changed by the board of trustees of the Fund with at least 60 days’ written notice provided to shareholders. Senior Loans hold the most senior position in the capital structure of a business entity, are secured with specific collateral and have a claim on the assets and/or stock of the Borrower that is senior to that held by unsecured creditors, subordinated debt holders and stockholders of the Borrower. Senior Loans are usually rated below investment grade or may also be unrated. As a result, the risks associated with Senior Loans are similar to the risks of below investment grade securities, although Senior Loans are senior and secured in contrast to other below investment grade securities, which are often subordinated or unsecured. Nevertheless, if a Borrower under a Senior Loan defaults or goes into bankruptcy, the Fund may recover only a fraction of what is owed on the Senior Loan or nothing at all. Senior Loans are subject to a number of risks described elsewhere in this Prospectus, including credit risk, liquidity risk and management risk. There is less readily available and reliable information about most Senior Loans than is the case for many other types of securities, including securities issued in transactions registered under the Securities Act of 1933, as amended, or registered under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). As a result, the Adviser will rely primarily on its own evaluation of a Borrower’s credit quality rather than on any available independent sources. Therefore, the Fund will be particularly dependent on the analytical abilities of the Adviser. The Fund will typically invest in Senior Loans rated below investment grade, which are considered speculative because of the credit risk of their issuers. Such companies are more likely than investment grade issuers to default on their payments of interest and principal owed to the Fund, and such defaults could reduce the Fund’s net asset value and income distributions. An economic downturn would generally lead to a higher non-payment rate, and a Senior Loan may lose significant market value before a default occurs. Moreover, any specific collateral used to secure a Senior Loan may decline in value or become illiquid, which would adversely affect the Senior Loan’s value. In general, the secondary trading market for Senior Loans is not well developed. No active trading market may exist for certain Senior Loans, which may make it difficult to value them. Illiquidity and adverse market conditions may mean that the Fund may not be able to sell Senior Loans quickly or at a fair price. To the extent that a secondary market does exist for certain Senior Loans, the market for them may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Senior Loans and other variable rate debt instruments are subject to the risk of payment defaults of scheduled interest or principal. Such payment defaults would result in a reduction of income to the Fund, a reduction in the value of the investment and a potential decrease in the net asset value of the Fund. Similarly, a sudden and significant increase in market interest rates may increase the risk for payment defaults and cause a decline in the value of these investments and in the Fund’s net asset value. Other factors (including, but not limited to, rating downgrades, credit deterioration, a large downward movement in stock prices, a disparity in supply and demand of certain securities or market conditions that reduce liquidity) can reduce the value of Senior Loans and other debt obligations, impairing the Fund’s net asset value. Although the Senior Loans in which the Fund will invest will be secured by collateral, there can be no assurance that such collateral could be readily liquidated or that the liquidation of such collateral would satisfy the Borrower’s obligation in the event of non-payment of scheduled interest or principal. In the event of the bankruptcy or insolvency of a Borrower, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a Senior Loan. In the event of a decline in the value of the already pledged collateral, if the terms of a Senior Loan do not require the Borrower to pledge additional collateral, the Fund will be exposed to the risk that the value of the collateral will not at all times equal or exceed the amount of the Borrower’s obligations under the Senior Loans. To the extent that a Senior Loan is collateralized by stock in the Borrower or its subsidiaries, such stock may lose some or all of its value in the event of the bankruptcy or insolvency of the Borrower. Those Senior Loans that are under-collateralized involve a greater risk of loss. Some Senior Loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the Senior Loans to presently existing or future indebtedness of the Borrower or take other action detrimental to lenders, including the Fund. Such court action could under certain circumstances include invalidation of Senior Loans. If legislation or state or federal regulations impose additional requirements or restrictions on the ability of financial institutions to make loans, the availability of Senior Loans for investment by the Fund may be adversely affected. In addition, such requirements or restrictions could reduce or eliminate sources of financing for certain Borrowers. This would increase the risk of default. If legislation or federal or state regulations require financial institutions to increase their capital requirements this may cause financial institutions to dispose of Senior Loans that are considered highly levered transactions. Such sales could result in prices that, in the opinion of the Adviser, do not represent fair value. If the Fund attempts to sell a Senior Loan at a time when a financial institution is engaging in such a sale, the price the Fund could get for the Senior Loan may be adversely affected. The Fund may acquire Senior Loans through assignments or participations. The Fund will typically acquire Senior Loans through assignment and may elevate a participation interest into an assignment as soon as practicably possible. The purchaser of an assignment typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the purchaser’s rights can be more restricted than those of the assigning institution, and the Fund may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. A participation typically results in a contractual relationship only with the institution participating out the interest, not with the Borrower. Sellers of participations typically include banks, broker-dealers, other financial institutions and lending institutions. The Adviser has adopted best execution procedures and guidelines to mitigate credit and counterparty risk in the atypical situation when the Fund must acquire a Senior Loan through a participation. The Adviser has established a risk and valuation committee that regularly reviews each broker-dealer counterparty for, among other things, its quality and the quality of its execution. The established procedures and guidelines require trades to be placed for execution only with broker-dealer counterparties approved by the risk and valuation committee of the Adviser. The factors considered by the committee when selecting and approving brokers and dealers include, but are not limited to: (i) quality, accuracy, and timeliness of execution, (ii) review of the reputation, financial strength and stability of the financial institution, (iii) willingness and ability of the counterparty to commit capital, (iv) ongoing reliability and (v) access to underwritten offerings and secondary markets. In purchasing participations, the Fund generally will have no right to enforce compliance by the Borrower with the terms of the loan agreement against the Borrower, and the Fund may not directly benefit from the collateral supporting the debt obligation in which it has purchased the participation. As a result, the Fund will be exposed to the credit risk of both the Borrower and the institution selling the participation. Further, in purchasing participations in lending syndicates, the Fund will not be able to conduct the due diligence on the Borrower or the quality of the Senior Loan with respect to which it is buying a participation that the Fund would otherwise conduct if it were investing directly in the Senior Loan, which may result in the Fund being exposed to greater credit or fraud risk with respect to the Borrower or the Senior Loan than the Fund expected when initially purchasing the participation. The Fund may obtain exposure to Senior Loans through the use of derivative instruments, which have become increasingly available. Although the Fund does not have an intention to do so, the Fund may utilize these instruments and similar instruments that may be available in the future. Derivative transactions involve the risk of loss due to unanticipated adverse changes in securities prices, interest rates, the inability to close out a position, imperfect correlation between a position and the desired hedge, tax constraints on closing out positions and portfolio management constraints on securities subject to such transactions. The potential loss on derivative instruments may be substantial relative to the initial investment therein. The Fund may also be subject to the risk that the counterparty in a derivative transaction will default on its obligations. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Subordinated Loans Risk The Fund may invest up to 20% of its Managed Assets in Subordinated Loans. Subordinated Loans generally are subject to similar risks as those associated with investments in Senior Loans except that such loans are subordinated in payment and/or lower in lien priority to first lien holders. In the event of default on a Subordinated Loan, the first priority lien holder has first claim to the underlying collateral of the loan. Subordinated Loans 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 unsecured or 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. Subordinated Loans generally have greater price volatility than Senior Loans and may be less liquid. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Structured Products Risk The Fund may invest up to 20% of its Managed Assets in structured products, including, without limitation, CLOs, structured notes, credit linked notes and derivatives, including credit derivatives. Holders of structured products bear risks of the underlying investments, index or reference obligation and are subject to counterparty risk. The Fund may have the right to receive payments only from the structured product, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain structured products enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in structured products generally pay their share of the structured product’s administrative and other expenses. Although it is difficult to predict whether the prices of indices and securities underlying structured products will rise or fall, these prices (and, therefore, the prices of structured products) will be influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a structured product uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining short-term financing, which may adversely affect the value of the structured products owned by the Fund. Certain structured products may be thinly traded or have a limited trading market. CLOs are typically privately offered and sold. As a result, investments in CLOs may be characterized by the Fund as illiquid securities. In addition to the general risks associated with debt securities discussed herein, CLOs carry additional risks, including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the investments in CLOs are subordinate to other classes or tranches thereof; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results. Investments in structured notes involve risks, including credit risk and market risk. Where the Fund’s investments in structured notes are based upon the movement of one or more factors, including currency exchange rates, interest rates, referenced bonds and stock indices, depending on the factor used and the use of multipliers or deflators, changes in interest rates and movement of the factor may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured note to be reduced to zero, and any further changes in the reference instrument may then reduce the principal amount payable on maturity. Structured notes may be less liquid than other types of securities and more volatile than the reference instrument or security underlying the note. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | CLO Risk In addition to the general risks associated with debt securities and structured products discussed herein, CLOs carry additional risks, including, but not limited to (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the investments in CLOs are subordinate to other classes or tranches thereof, (iv) the potential of spread compression in the underlying loans of the CLO, which could reduce credit enhancement in the CLOs and (v) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results. CLO junior debt securities that the Fund may acquire are subordinated to more senior tranches of CLO debt. CLO junior debt securities are subject to increased risks of default relative to the holders of superior priority interests in the same securities. In addition, at the time of issuance, CLO equity securities are under-collateralized in that the liabilities of a CLO at inception exceed its total assets. Though not exclusively, the Fund will typically be in a first loss or subordinated position with respect to realized losses on the assets of the CLOs in which it is invested. The Fund may recognize phantom taxable income from its investments in the subordinated tranches of CLOs. Between the closing date and the effective date of a CLO, the CLO collateral manager will generally expect to purchase additional collateral obligations for the CLO. During this period, the price and availability of these collateral obligations may be adversely affected by a number of market factors, including price volatility and availability of investments suitable for the CLO, which could hamper the ability of the collateral manager to acquire a portfolio of collateral obligations that will satisfy specified concentration limitations and allow the CLO to reach the initial par amount of collateral prior to the effective date. An inability or delay in reaching the target initial par amount of collateral may adversely affect the timing and amount of interest or principal payments received by the holders of the CLO debt securities and distributions of the CLO on equity securities and could result in early redemptions which may cause CLO debt and equity investors to receive less than the face value of their investment. The failure by a CLO in which the Fund invests to satisfy financial covenants, including with respect to adequate collateralization and/or interest coverage tests, could lead to a reduction in the CLO’s payments to the Fund. In the event that a CLO fails certain tests, holders of CLO senior debt may be entitled to additional payments that would, in turn, reduce the payments the Fund would otherwise be entitled to receive. Separately, the Fund may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms, which may include the waiver of certain financial covenants, with a defaulting CLO or any other investment the Fund may make. If any of these occur, it could adversely affect the Fund’s operating results and cash flows. The Fund’s CLO investments are exposed to leveraged credit risk. If certain minimum collateral value ratios and/or interest coverage ratios are not met by a CLO, primarily due to senior secured loan defaults, then cash flow that otherwise would have been available to pay distributions to the Fund on its CLO investments may instead be used to redeem any senior notes or to purchase additional senior secured loans, until the ratios again exceed the minimum required levels or any senior notes are repaid in full. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Liquidity Risk The Fund may invest up to 50% of its Managed Assets in securities that are considered illiquid. “Illiquid securities” are securities which cannot be sold within seven days in the ordinary course of business at approximately the value used by the Fund in determining its net asset value. The Fund may not be able to readily dispose of such securities at prices that approximate those at which the Fund could sell such securities if they were more widely-traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Limited liquidity can also affect the market price of securities, thereby adversely affecting the Fund’s net asset value and ability to make dividend distributions. Some Senior Loans are not readily marketable and may be subject to restrictions on resale. Senior Loans are not listed on any national securities exchange and no active trading market may exist for the Senior Loans in which the Fund will invest. Where a secondary market exists, the market for some Senior Loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. The Fund has no limitation on the amount of its assets which may be invested in securities that are not readily marketable or are subject to restrictions on resale. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  | Leverage Risk The Fund currently anticipates utilizing leverage in an aggregate amount of up to 331/3% of its Managed Assets at the time the leverage is incurred in order to buy additional securities. The Fund currently anticipates that it will issue preferred shares and/or notes and it may also borrow funds from banks and other financial institutions. The use of leverage to purchase additional securities creates an opportunity for increased common share dividends, but also creates risks for the holders of common shares. Leverage is a speculative technique that exposes the Fund to greater risk and increased costs than if it were not implemented. Increases and decreases in the value of the Fund’s portfolio will be magnified when the Fund uses leverage. As a result, leverage may cause greater changes in the Fund’s net asset value which will be borne entirely by the Fund’s common shareholders. The Fund will also have to pay dividends on its preferred shares or interest on its notes or borrowings, if any, which will increase expenses and may reduce the Fund’s return. These dividend payments or interest expenses may be greater than the Fund’s return on the underlying investments. The Fund’s leveraging strategy may not be successful. The Fund intends to issue preferred shares and/or notes as a form of leverage. Any such leverage of the Fund would be senior to the Fund’s common shares, such that holders of preferred shares and/or notes would have priority over the common shareholders in the distribution of the Fund’s assets, including dividends, distributions of principal proceeds after the reinvestment period and liquidating distributions. If preferred shares are issued and outstanding, holders of the preferred shares would elect two trustees of the Fund, and would vote separately as a class on certain matters which may at times give holders of preferred shares disproportionate influence over the Fund’s affairs. If the preferred shares were limited in their term, redemptions of such preferred shares would require the Fund to liquidate its investments and would reduce the Fund’s use of leverage, which could negatively impact common shareholders. In addition, the Fund will pay (and the holders of common shares will bear) all costs and expenses relating to the issuance and ongoing maintenance of any preferred shares and/or notes issued by the Fund, including higher advisory fees. Accordingly, the Fund cannot assure you that the issuance of preferred shares and/or notes will result in a higher yield or return to the holders of the common shares. The Fund anticipates that any money borrowed from a bank or other financial institution for investment purposes will accrue interest based on shorter-term interest rates that would be periodically reset. So long as the Fund’s portfolio provides a higher rate of return, net of expenses, than the interest rate on borrowed money, as reset periodically, the leverage may cause the holders of common shares to receive a higher current rate of return than if the Fund were not leveraged. If, however, long-term and/or short-term rates rise, the interest rate on borrowed money could exceed the rate of return on securities held by the Fund, reducing return to the holders of common shares. Recent developments in the credit markets may adversely affect the ability of the Fund to borrow for investment purposes and may increase the costs of such borrowings, which would reduce returns to the holders of common shares. There is no assurance that a leveraging strategy will be successful. Leverage involves risks and special considerations for common shareholders, including:
| ● | the likelihood of greater volatility of net asset value, market price and dividend rate of the common shares than a comparable portfolio without leverage;
| ● | the risk that fluctuations in interest rates on borrowings and short-term debt or in dividend payments on, principal proceeds distributed to, or redemption of any preferred shares and/or notes that the Fund has issued will reduce the return to the common shareholders;
| ● | the effect of leverage in a declining market, which is likely to cause a greater decline in the net asset value of the common shares than if the Fund were not leveraged, which may result in a greater decline in the market price of the common shares;
| ● | when the Fund uses financial leverage, the investment advisory and administrative fees payable to the Adviser and ALPS will be higher than if the Fund did not use leverage, and may provide a financial incentive to the Adviser to increase the Fund’s use of leverage and create an inherent conflict of interest; and
| ● | leverage may increase expenses, which may reduce total return.
If the Fund issues preferred shares and/or notes or borrows money the Fund will be required to maintain asset coverage in conformity with the requirements of the 1940 Act. The Fund may be subject to certain restrictions on investments imposed by guidelines of one or more rating agencies, which may issue ratings for the preferred shares and/or notes or short-term debt securities issued by the Fund. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act. Certain types of borrowings by the Fund may result in the Fund being subject to covenants in credit agreements relating to asset coverage and portfolio composition requirements. These covenants and restrictions may negatively affect the Fund’s ability to achieve its investment objectives. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  | Foreign Currency Risk Because the Fund may invest in securities denominated or quoted in currencies other than the U.S. dollar, changes in foreign currency exchange rates may affect the value of securities in the Fund and the unrealized appreciation or depreciation of investments. Currencies of certain countries may be volatile and therefore may affect the value of securities denominated in such currencies, which means that the Fund’s net asset value could decline as a result of changes in the exchange rates between foreign currencies and the U.S. dollar. The Adviser may, but is not required to, elect for the Fund to seek to protect itself from changes in currency exchange rates through hedging transactions depending on market conditions. The Fund may incur costs in connection with the conversions between various currencies. In addition, certain countries may impose foreign currency exchange controls or other restrictions on the repatriation, transferability or convertibility of currency. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
