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, 2024 (filed with the SEC on March 28, 2025), which could materially affect our business, financial condition or operating results. *Changes to United States tariff and import/export regulations may have a negative effect on our portfolio companies.* The United States has recently enacted and proposed to enact significant new tariffs. Additionally, there has been ongoing discussion and commentary regarding potential significant changes to U.S. trade policies, treaties and tariffs, creating significant uncertainty about the future relationship between the U.S. and other countries with respect to such trade policies, treaties and tariffs. These developments, or the perception that any of them could occur, may have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly reduce global trade and, in particular, trade between the impacted nations and the U.S. Any of these factors could depress economic activity and restrict our portfolio companies’ access to suppliers or customers and have a material adverse effect on their business, financial condition and results of operations, which in turn would negatively impact us, including the value of our investments in such companies.
Effects of Leverage [Table Text Block]	The use of leverage 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 “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 “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 our use of leverage, we intend to borrow money to purchase assets in order to comply with certain regulatory requirements for RICs, including diversification requirements. Accordingly, we have entered into the Loan Agreement with BNP and have engaged in borrowings under the Loan Agreement for this purpose. Although we expect 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.
