General Description of Registrant [Abstract]
Risk Factors [Table Text Block]	Item 1A. Risk Factors You should carefully consider the risks referenced below and all other information contained in this Quarterly Report on Form 10-Q, including our interim consolidated financial statements and the related notes thereto, before making a decision to purchase our securities. Any such risks and uncertainties are not the only ones facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may have a material adverse effect on our business, financial condition and/or operating results, as well as the value of our securities. In addition to the other information set forth in this report, you should carefully consider the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023 (filed with the SEC on March 29, 2024), which could materially affect our business, financial condition or operating results.
Effects of Leverage [Table Text Block]	The use of leverage also involves significant risks. Certain trading practices and transactions, which may include, among others, reverse repurchase agreements and the use of when-issued, delayed delivery or forward commitment transactions, may be considered to be borrowings or involve leverage and thus are also subject to 1940 Act restrictions. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings for these purposes. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the asset coverage requirement. These investments may include certain investments or instruments that have embedded leverage, which may increase the risk of loss from such investments, but are not considered to be borrowings. In connection with its use of leverage, the Company intends to borrow money to purchase assets in order to comply with certain regulatory requirements for RICs, including diversification requirements. Accordingly, the Company has entered into a committed facility agreement with BNP Paribas Prime Brokerage International, Limited (“BNP”) (the “Loan Agreement”) and has engaged in borrowings under the Loan Agreement for this purpose. Although the Company expects to continue to be able to borrow under the Loan Agreement as needed for this purpose, we are subject to the risk that BNP can terminate the Loan Agreement or that the amount available to be borrowed thereunder will be insufficient to allow us to satisfy the applicable requirements. The amount of leverage that we employ will depend on our Adviser’s and our Board of Directors’ assessment of market conditions and other factors at the time of any proposed borrowing, and there can be no assurance that we will use leverage or that our leveraging strategy will be successful during any period in which it is employed.
