The following tables provide a summary of MSC Income Fund’s investments in the Private Loan, LMM and Middle Market portfolios as of March 31, 2024 and December 31, 2023 (this information excludes Other Portfolio investments, which are discussed further below).
As of March 31, 2024
Private Loan LMM (a) Middle Market
(dollars in millions)
Number of portfolio companies 79  51  15 
Fair value $ 631.4  $ 391.6  $ 68.4 
Cost $ 624.3  $ 319.2  $ 97.7 
Debt investments as a % of portfolio (at cost) 94.6  % 70.3  % 91.7  %
Equity investments as a % of portfolio (at cost) 5.4  % 29.7  % 8.3  %
% of debt investments at cost secured by first priority lien 99.9  % 99.9  % 99.9  %
Weighted-average annual effective yield (b) 13.0  % 13.0  % 13.4  %
Average EBITDA (c) $ 34.7  $ 9.2  $ 62.5 
___________________
(a)At March 31, 2024, MSC Income Fund had equity ownership in all of its LMM portfolio companies, and the average fully diluted equity ownership in those portfolio companies was 9%.
(b)The weighted-average annual effective yields were computed using the effective interest rates for all debt investments at cost as of March 31, 2024, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt instruments and any debt investments on non-accrual status. The weighted-average annual effective yield on MSC Income Fund’s debt portfolio as of March 31, 2024 including debt investments on non-accrual status was 12.6% for its Private Loan portfolio, 13.0% for its LMM portfolio and 10.1% for its Middle Market portfolio. The weighted-average annual effective yield is not reflective of what an investor in shares of MSC Income Fund’s common stock will realize on its investment because it does not reflect MSC Income Fund’s utilization of debt capital in its capital structure, MSC Income Fund’s expenses or any sales load paid by an investor.
(c)The average EBITDA is calculated using a weighted-average for the Private Loan and Middle Market portfolios and a simple average for the LMM portfolio. These calculations exclude certain portfolio companies, including one Private Loan portfolio company, two LMM portfolio companies and one Middle Market portfolio company, as EBITDA is not a meaningful valuation metric for MSC Income Fund’s investments in these portfolio companies, and those portfolio companies whose primary purpose is to own real estate.
