General Description of Registrant [Abstract]
Investment Objectives and Practices [Text Block]	Our investment objective is to generate high current income by investing primarily in fixed income instruments, including broadly syndicated bank loans, structured products, mezzanine financings and senior secured bonds. We provide moderate liquidity to our shareholders by offering a quarterly share repurchase program. As of September 30, 2025, approximately 1,139,227 shares have been tendered through the share repurchase program. Broadly syndicated loans are generally more liquid than directly originated investments and may provide more attractive financing terms than less liquid assets. Mezzanine financings are generally unrated or below investment grade rated investments that have greater credit and liquidity risk than more highly rated debt obligations. Moreover, mezzanine financings are generally unsecured and subordinate to other obligations of the obligor and are subject to many of the same risks as those associated with high-yield debt securities.
Risk Factors [Table Text Block]	Item 1A. Risk Factors. In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (the “Annual Report on Form 10-K”), which could materially affect our business, financial condition and/or operating results. The risks described in our Annual Report on Form 10-K are not the only risks we face. Additional risks and uncertainties that are not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. Other than the risk factors below, during the three months ended September 30, 2025, there have been no material changes from the risk factors set forth in our Annual Report on Form 10-K.
