General Description of Registrant [Abstract] |
Investment Objectives and Practices [Text Block] | Our investment objective is to generate current income and capital appreciation through the sourcing and origination of debt securities at all levels of the capital structure, including first and second lien debt, notes, bonds and mezzanine securities. The first lien debt may include traditional first lien senior secured loans or unitranche loans. Unitranche loans combine characteristics of traditional first lien senior secured loans as well as second lien and subordinated loans. Unitranche loans will expose us to the risks associated with second lien and subordinated loans to the extent we invest in the “last out” tranche. In some cases, our investments may also include equity interests. Our primary focus is in the debt of defensive growth companies, which are defined as generally exhibiting the following characteristics: (i) sustainable secular growth drivers, (ii) high barriers to competitive entry, (iii) high free cash flow after capital expenditure and working capital needs, (iv) high returns on assets and (v) niche market dominance. Similar to us, SBIC I's and SBIC II's investment objectives are to generate current income and capital appreciation under our investment criteria. However, SBIC I's and SBIC II's investments must be in SBA-eligible small businesses. Our portfolio may be concentrated in a limited number of industries. As of June 30, 2022, our top five industry concentrations were software, healthcare services, business services, education and investment funds (which includes our investments in our joint ventures).
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 Item 1A. Risk Factors in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which could materially affect our business, financial condition and/or operating results, including the Risk Factor titled "Small Business Credit Availability Act allows us to incur additional leverage, which could increase the risk of investing in our securities". The risks described in our Annual Report on Form 10-K are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition and/or operating results. There have been no material changes during the six months ended June 30, 2022 to the risk factors discussed in Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2021.
