General Description of Registrant [Abstract] |
Investment Objectives and Practices [Text Block] | We were established for the purpose of investing in debt and equity securities of established private businesses operating in the U.S. Our investment objectives are to: (1) achieve and grow current income by investing in debt securities of established lower middle market businesses that we believe will provide stable earnings and cash flow to pay expenses, make principal and interest payments on our outstanding indebtedness and make distributions to stockholders that grow over time; and (2) provide our stockholders with long-term capital appreciation in the value of our assets by investing in equity securities of established businesses that we believe can grow over time to permit us to sell our equity investments for capital gains. To achieve our investment objectives, our investment strategy is to invest in several categories of debt and equity securities, with each investment generally ranging from $8 million to $30 million, although investment size may vary, depending upon our total assets or available capital at the time of investment. We expect that our investment portfolio over time will consist of approximately 90.0% debt investments and 10.0% equity investments, at cost.We focus on investing in lower middle market companies (which we generally define as companies with annual earnings before interest, taxes, depreciation and amortization of $3 million to $15 million) in the U.S. that meet certain criteria, including the following: the sustainability of the business’ free cash flow and its ability to grow it over time, adequate assets for loan collateral, experienced management teams with a significant ownership interest in the borrower, reasonable capitalization of the borrower, including an ample equity contribution or cushion based on prevailing enterprise valuation multiples and, to a lesser extent, the potential to realize appreciation and gain liquidity in our equity position, if any. We lend to borrowers that need funds for growth capital or to finance acquisitions or recapitalize or refinance their existing debt facilities. We seek to avoid investing in high-risk, early-stage enterprises. Our targeted portfolio companies are generally considered too small for the larger capital marketplace.

Capital Stock, Long-Term Debt, and Other Securities [Abstract] |
Long Term Debt, Structuring [Text Block] | In November 2021, we completed a private placement of $50.0 million aggregate principal amount of 3.75% Notes due 2027 (the “2027 Notes”) for net proceeds of approximately $48.5 million after deducting initial purchasers’ costs, commissions and offering expenses borne by us. The 2027 Notes will mature on May 1, 2027 and may be redeemed in whole or in part at any time or from time to time at the Company’s option prior to maturity at par plus a “make-whole” premium, if applicable. The 2027 Notes bear interest at a rate of 3.75% per year. Interest is payable semi-annually on May 1 and November 1 of each year (which equates to approximately $1.9 million per year). In April 2022, pursuant to the registration rights agreement we entered into in connection with the 2027 Notes, we conducted an exchange offer through which we offered to exchange all of our then outstanding 2027 Notes (the “Restricted Notes”) that were issued on November 4, 2021, for an equal aggregate principal amount of our new 3.75% Notes due 2027 (the “Exchange Notes”) that had been registered with the SEC under the Securities Act of 1933, as amended. The terms of the Exchange Notes are identical to those of the outstanding Restricted Notes, except that the transfer restrictions and registration rights relating to the Restricted Notes do not apply to the Exchange Notes, and the Exchange Notes do not provide for the payment of additional interest in the event of a registration default.

Long Term Debt, Structuring [Text Block] | In December 2020, we completed an offering of $100.0 million aggregate principal amount of 5.125% Notes due 2026 (the “2026 Notes”) for net proceeds of approximately $97.7 million after deducting underwriting discounts, commissions and offering expenses borne by us. In March 2021, we completed an offering of an additional $50.0 million aggregate principal amount of the 2026 Notes for net proceeds of approximately $50.6 million after adding premiums and deducting underwriting costs, commissions and offering expenses borne by us. The 2026 Notes will mature on January 31, 2026 and may be redeemed in whole or in part at any time or from time to time at the Company’s option prior to maturity at par plus a “make-whole” premium, if applicable. The 2026 Notes bear interest at a rate of 5.125% per year. Interest is payable semiannually on January 31 and July 31 of each year (which equates to approximately $7.7 million per year).

Long Term Debt, Dividends and Covenants [Text Block] | The indenture relating to the 2027 Notes and the 2026 Notes contains certain covenants, including (i) an inability to incur additional debt or issue additional debt or preferred securities unless the Company’s asset coverage meets the threshold specified in the 1940 Act after such borrowing, (ii) an inability to declare any dividend or distribution (except a dividend payable in our stock) on a class of our capital stock or to purchase shares of our capital stock unless the Company’s asset coverage meets the threshold specified in the 1940 Act at the time of (and giving effect to) such declaration or purchase, and (iii) if, at any time, we are not subject to the reporting requirements of the Exchange Act, we will provide the holders of the 2027 Notes and the 2026 Notes, as applicable, and the trustee with audited annual consolidated financial statements and unaudited interim consolidated financial statements. The 2027 Notes and 2026 Notes are recorded at the principal amount, plus applicable premiums, less discounts and offering costs, on our Consolidated Statements of Assets and Liabilities.
