Page 14 CSWC Investment Portfolio Composition Note: All metrics above exclude the I-45 Senior Loan Fund (1) At June 30, 2022 and March 31, 2022, we had equity ownership in approximately 59% and 57%, respectively, of our investments (2) The weighted-average annual effective yields were computed using the effective interest rates during the quarter for all debt investments at cost as of June 30, 2022, including accretion of original issue discount but excluding fees payable upon repayment of the debt instruments. As of June 30, 2022, there were four investments on non-accrual status. As of March 31, 2022, there were three investments on non-accrual status. Weighted-average annual effective yield is not a return to shareholders and is higher than what an investor in shares in our common stock will realize on its investment because it does not reflect our expenses or any sales load paid by an investor (3) Includes CSWC debt investments only. Weighted average EBITDA metric is calculated using investment cost basis weighting. For the quarter ended June 30, 2022, six portfolio companies are excluded from this calculation due to a reported debt to adjusted EBITDA ratio that was not meaningful. For the quarter ended March 31, 2022, three portfolio companies are excluded from this calculation due to a reported debt to adjusted EBITDA ratio that was not meaningful (4) Includes CSWC debt investments only. Calculated as the amount of each portfolio company’s debt (including CSWC’s position and debt senior or pari passu to CSWC’s position, but excluding debt subordinated to CSWC’s position) in the capital structure divided by each portfolio company’s adjusted EBITDA. Weighted average leverage is calculated using investment cost basis weighting. Management uses this metric as a guide to evaluate relative risk of its position in each portfolio debt investment. For the quarter ended June 30, 2022, six portfolio companies are excluded from this calculation due to a reported debt to adjusted EBITDA ratio that was not meaningful. For the quarter ended March 31, 2022, three portfolio companies are excluded from this calculation due to a reported debt to adjusted EBITDA ratio that was not meaningful Maintaining appropriate portfolio leverage while receiving attractive risk-adjusted returns Investment Portfolio - Statistics (in $000's) 3/31/2022 6/30/2022 Total CSWC Portfolio Total CSWC Portfolio Number of Portfolio Companies 72 75 Total Cost $862,303 $943,496 Total Fair Value $879,011 $954,939 Average Hold Size Debt Investments (at Fair Value) $12,213 $12,727 Average Hold Size Equity Investments (at Fair Value) $2,078 $2,082 % First Lien Investments (at Fair Value) 84.2% 85.4% % Second Lien Investments (at Fair Value) 6.0% 5.1% % Subordinated Debt Investments (at Fair Value) 0.1% 0.1% % Equity (at Fair Value) (1) 9.7% 9.4% Wtd.
