Schedule of Investments [Abstract] |
Portfolio Company Investments | Note 3. Portfolio Company Investments The Company’s portfolio investments principally consist of secured and unsecured debt, equity warrants and direct equity investments primarily in privately held companies. The debt investments may or may not be secured by either a first or second lien on the assets of the portfolio company. The debt investments generally bear interest at fixed rates or variable rates, and generally mature between five and seven years from the original investment. In connection with a debt investment, the Company also may receive nominally priced equity warrants and/or make a direct equity investment in the portfolio company. The Company’s warrants or equity investments may be investments in a holding company related to the portfolio company. In addition, the Company periodically makes equity investments in its portfolio companies through Taxable Subsidiaries. In both situations, the investment is generally reported under the name of the operating company on the consolidated schedules of investments. As of December 31, 2022, the Company had active investments in 76 portfolio companies and residual investments in two portfolio companies that have sold their underlying operations. The aggregate fair value of the total portfolio was $860,329 and the weighted average effective yield on the Company’s debt investments was 13.8% as of such date. As of December 31, 2022, the Company held equity investments in 74.4% of its portfolio companies and the average fully diluted equity ownership in those portfolio companies was 4.0%. As of December 31, 2021, the Company had active investments in 70 portfolio companies and residual investments in eight portfolio companies that have sold their underlying operations. The aggregate fair value of the total portfolio was $719,124 and the weighted average effective yield on the Company’s debt investments was 12.3% as of such date. As of December 31, 2021, the Company held equity investments in 82.1% of its portfolio companies and the average fully diluted equity ownership in those portfolio companies was 4.7%. The weighted average yield of the Company’s debt investments is not the same as a return on investment for its stockholders but, rather, relates to a portion of the Company’s investment portfolio and is calculated before the payment of all of the Company’s and its subsidiaries’ fees and expenses. The weighted average yields were computed using the effective interest rates for debt investments at cost as of December 31, 2022 and 2021, including accretion of OID and debt investment origination fees, but excluding investments on non-accrual status and investments recorded as a secured borrowing, if any. Purchases of debt and equity investments for the years ended December 31, 2022, 2021 and 2020 totaled $333,846, $346,737, and $189,996, respectively. Proceeds from sales and repayments, including principal, return of capital distributions and realized gains, of portfolio investments for the years ended December 31, 2022, 2021 and 2020 totaled $193,980, $472,782, and $210,774 respectively. Investments by type with corresponding percentage of total portfolio investments consisted of the following:
