Marks reflect each BDC’s own fair-value estimates as reported to the SEC, not traded prices. Private-credit loans are predominantly Level 3 under ASC 820 — valued from unobservable inputs and determined in good faith by each BDC’s board, so figures are estimates as of the filing date and are not directly comparable across managers. Informational only; not investment advice or a valuation.
About Main Street Capital Corporation
Main Street Capital Corporation (MAIN) is a publicly traded Business Development Company (BDC) — essentially a publicly listed fund that lends money to mid-sized private companies. In plain English: BDCs raise money from public investors and lend it to businesses that are too small for Wall Street banks. By law, they must pay out at least 90% of their profits as dividends, which is why BDC yields are often 8–12%. Main Street Capital Corporation discloses its full loan portfolio through SEC filings.
