The following tables provide a summary of Main Street’s investments in the LMM, Private Loan and Middle Market portfolios as of September 30, 2023 and December 31, 2022 (this information excludes Other Portfolio investments, short-term portfolio investments and the External Investment Manager, which are discussed further below).
As of September 30, 2023
LMM (a) Private Loan Middle Market
(dollars in millions)
Number of portfolio companies 79  89  27 
Fair value $ 2,190.4  $ 1,544.0  $ 290.6 
Cost $ 1,716.9  $ 1,577.5  $ 343.3 
Debt investments as a % of portfolio (at cost) 71.9  % 96.2  % 92.7  %
Equity investments as a % of portfolio (at cost) 28.1  % 3.8  % 7.3  %
% of debt investments at cost secured by first priority lien 99.2  % 99.5  % 99.2  %
Weighted-average annual effective yield (b) 12.9  % 12.9  % 12.3  %
Average EBITDA (c) $ 8.2  $ 28.8  $ 65.7 
____________________
(a)At September 30, 2023, Main Street had equity ownership in all of its LMM portfolio companies, and the average fully diluted equity ownership in those portfolio companies was 40%.
(b)The weighted-average annual effective yields were computed using the effective interest rates for all debt investments at cost as of September 30, 2023, 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 Main Street’s debt portfolio as of September 30, 2023 including debt investments on non-accrual status was 12.8% for its LMM portfolio, 12.2% for its Private Loan portfolio and 10.9% for its Middle Market portfolio. The weighted-average annual effective yield is not reflective of what an investor in shares of Main Street’s common stock will realize on its investment because it does not reflect changes in the market value of Main Street’s stock, Main Street’s utilization of debt capital in its capital structure, Main Street’s expenses or any sales load paid by an investor.
(c)The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the Private Loan and Middle Market portfolios. These calculations exclude certain portfolio companies, including two LMM portfolio companies and two Private Loan portfolio companies, as EBITDA is not a meaningful valuation metric for Main Street’s investments in these portfolio companies, and those portfolio companies whose primary purpose is to own real estate.
