What Is a BDC? Business Development Companies Explained for Accredited Investors

The private credit market has expanded fast. According to the SEC's investor education page on BDCs, Business Development Companies were created by Congress in 1980 as an amendment to the Investment Company Act of 1940 to channel capital into growing American businesses that could not access public markets. Total BDC industry gross assets under management reached $575 billion in Q1 2026, up 21% year-over-year. Non-traded BDCs now account for roughly $220 billion of that total. For accredited investors seeking income above what investment-grade bonds pay, BDCs deserve a close look, and an equally close reading of the fine print.

The Legal Foundation: What Makes a BDC a BDC

A BDC is a specific type of closed-end investment company defined under Sections 54-65 of the Investment Company Act of 1940. Congress created the structure to make private credit accessible to ordinary shareholders through a registered, exchange-listed vehicle. That regulatory wrapper imposes real obligations on BDC managers.

The core requirement: a BDC must invest at least 70% of its assets in "qualifying assets." The SEC defines qualifying assets primarily as securities of eligible portfolio companies. Those companies must be US-based, not publicly traded on a national exchange, and typically generate annual revenue under $250 million. That definition points the portfolio toward lower middle-market and middle-market borrowers that banks have largely abandoned since the 2008 financial crisis tightened capital requirements.

BDCs also must make available significant managerial assistance to portfolio companies. In practice, most BDCs fulfill this through board seats, advisory services, or formal consulting arrangements. The requirement distinguishes a BDC from a passive bond fund and gives managers a justification for charging fees that resemble private equity structures: typically a 1.5% management fee on assets and a 20% performance fee above an 8% hurdle rate.

For a deeper look at BDC formation and registration mechanics, the Mayer Brown BDC Guide for Capital Markets covers the Section 55 asset coverage tests and the Section 57 co-investment rules governing how affiliated managers can act together inside the same deal.

How BDC Economics Work: The 90% Distribution Rule

A BDC earns its yields the same way a bank earns its net interest margin: it borrows cheaply and lends expensively. The fund raises equity capital through a public offering, then issues bonds, draws credit facilities, and issues preferred shares to add leverage on top of that equity base. The spread between its cost of funds and the interest rate it charges portfolio companies flows to shareholders as dividends.

To qualify as a Regulated Investment Company (RIC) under Subchapter M of the Internal Revenue Code, a BDC must distribute at least 90% of its taxable investment income each year. That distribution mandate eliminates the corporate tax at the fund level. Income passes through directly to shareholders, who pay tax at their individual rate. The structure is similar to a REIT, applied to credit rather than real estate.

The math on yields is straightforward. A BDC earning 12% on its loan portfolio, funded 50% by equity at zero cost and 50% by debt at 5%, earns a blended return of roughly 19% on equity before expenses. After a 3.5% all-in fee load, net return to equity runs about 15-16%. The 90% distribution requirement means most of that flows out as dividends rather than being retained. That is how BDC dividend yields reach 9-12% when investment-grade bonds pay 5-7%.

Ares Capital Corporation, the largest publicly traded BDC, reported a portfolio fair value of $29.5 billion in Q1 2026 and an annualized dividend yield of 10.2%, based on its regular quarterly dividend and share price as of that filing. ARCC trades on the NASDAQ under the ticker ARCC and publishes its quarterly reports at arcc.com.

The 2018 SBCAA Leverage Change: What It Means for Returns and Risk

Before 2018, BDCs operated under a 200% asset coverage requirement. That meant a BDC could hold $1 of debt for every $1 of equity, a 1-to-1 debt-to-equity ratio. The Small Business Credit Availability Act of 2018 (SBCAA) cut the asset coverage floor to 150%. That single change allowed BDCs to carry $2 of debt for every $1 of equity, doubling the permissible leverage.

Higher leverage amplifies returns in normal credit conditions. A BDC running at 1.5-to-1 debt-to-equity earns more net interest income per dollar of equity than one running at 0.9-to-1. Most large BDCs have moved close to the new regulatory maximum since 2018. That creates a specific risk: when credit deteriorates, losses hit a smaller equity cushion, which can push NAV down sharply.

The 2020 COVID shock was the first real test of post-SBCAA leverage levels. Most externally managed BDCs saw NAV per share fall 15-30% in Q1 and Q2 2020 before recovering as credit markets reopened. BDCs with lower starting leverage came out of that period with smaller NAV declines. For investors entering today, the 2-to-1 ceiling is a feature and a warning: higher income in good years, larger drawdowns in bad ones.

BDC Comparison: ARCC vs. Blue Owl Capital Corporation vs. FS KKR

Sources: company Q1 2026 filings, AIN research. Yields reflect annualized most-recent quarterly dividends divided by NAV per share. Non-accrual rates as percentage of portfolio fair value. AUM figures are approximate.

The table shows the trade-off clearly. FS KKR pays a higher yield, but it carries more leverage and a higher non-accrual rate. The industry median non-accrual rate stood at 2.8% of portfolio fair value in Q1 2026. FS KKR sits above that median. ARCC and Blue Owl sit below it. That difference matters: a 1% non-accrual rate sounds small, but on a $29.5 billion portfolio, it represents roughly $295 million of impaired assets that are no longer generating cash interest income.

Publicly Traded vs. Non-Traded BDCs: The Liquidity Difference

Publicly traded BDCs like ARCC trade on national exchanges. An investor can buy or sell shares any business day at the market price. That daily liquidity is one of the most valuable features of the publicly traded BDC structure, and it distinguishes BDCs from direct private credit funds or interval funds where redemptions are restricted.

Non-traded BDCs do not trade on exchanges. Instead, they use quarterly redemption programs, typically capping total repurchases at 5% of NAV per quarter, or 20% of NAV per year. In practice, when redemption requests exceed those limits, a fund gates withdrawals, meaning it honors only a portion of each investor's request until the queue clears.

That risk materialized in June 2026. Apollo throttled withdrawals from its $26 billion private credit fund after exit requests rose sharply, as reported by Investment News. Investors in that vehicle who needed capital faced a queue. Investors in ARCC sold shares on NASDAQ the same morning at a disclosed price. The structural difference is not subtle.

We covered the Apollo gating episode in detail in our report on Apollo private credit redemption gates. For a broader look at how interval funds handle liquidity constraints, see our guide on interval funds and liquidity for accredited investors.

Non-traded BDCs often pay slightly higher yields to compensate for the illiquidity premium. Whether that premium is adequate depends on your time horizon and your need for capital access. A 50-to-100 basis point yield pickup rarely justifies a 90-day exit queue for investors who hold BDCs as a meaningful portion of their income portfolio.

For context on the broader private credit slowdown that is driving redemption pressure across non-traded vehicles, our coverage of the Coller Capital 2026 LP survey on private credit cooling is worth reading before allocating to any non-traded structure.

5 Metrics to Check Before Buying a BDC

1. Non-Accrual Rate. This is the share of the portfolio, measured at fair value, where the BDC has stopped recognizing interest income because the borrower is impaired or in default. The Q1 2026 industry median sits at 2.8%. Any BDC running above 4% deserves a close read of what is driving that figure. Rising non-accruals are an early signal of NAV erosion to come.
2. Debt-to-Equity Ratio. The SBCAA allows up to 2-to-1 debt-to-equity. A BDC running at 1.7-to-1 or higher is operating near the regulatory ceiling and has almost no room to add borrowing if it needs to support portfolio companies or acquire discounted assets during a downturn. Most well-managed BDCs target 1.0-to-1.25-to-1 and keep dry powder available.
3. Premium or Discount to NAV. Publicly traded BDCs can trade above or below their reported net asset value per share. Buying at a premium to NAV means paying more than the stated value of the loan book. Buying at a discount offers a margin of safety. ARCC has historically traded at a modest premium, reflecting market confidence in its portfolio quality. A BDC trading at a 15-20% discount sometimes signals credit stress rather than opportunity.
4. PIK Income Percentage. Payment-in-kind income is interest that the borrower pays in additional principal rather than cash. PIK income appears on the BDC's income statement and counts toward the 90% distribution calculation, but it does not generate actual cash flow until the loan is repaid or refinanced. A BDC with 20% or more of its total investment income coming from PIK is generating significant non-cash income. That is a quality concern because PIK income is harder to collect if a borrower deteriorates.
5. Vintage Year Concentration. BDCs that deployed large amounts of capital in 2021 and 2022 did so at historically tight credit spreads and loose documentation standards. Those vintages now face refinancing risk as loans mature into a higher-rate, more selective lending environment. Ask the manager what percentage of the portfolio was originated in 2021-2022 and when those loans mature. Heavy concentration in those years increases the probability of both refinancing pressure and credit losses.

These five checks do not replace full due diligence, but they separate informed allocation from yield-chasing. BDC filings are public. The SEC requires quarterly N-2 and 10-Q filings disclosing every portfolio company, fair value marks, and income breakdowns. Reading one filing takes under two hours.

Who BDCs Are Right For

BDCs fit accredited investors who want income above bond market rates, prefer a regulated and transparent structure over direct private credit funds, and can accept the credit risk inherent in lending to sub-investment-grade companies. The daily liquidity of publicly traded BDCs makes them suitable for taxable accounts where an investor may need to rebalance.

BDCs are not appropriate for investors who cannot tolerate NAV volatility. A 20% NAV decline during a credit cycle is not a failure of the structure. It is the structure working as designed: levered credit exposure priced at market value. Investors who held ARCC through 2020 recovered fully within 18 months. Investors who needed cash during the trough sold at losses they did not need to realize.

At $575 billion in total gross assets, the BDC industry now moves credit markets. When BDCs collectively tighten standards, middle-market companies feel it. When BDCs compete aggressively for deals, spreads compress and credit terms loosen. BDC origination volumes and spread data serve as a useful proxy for private credit conditions broadly, even for investors holding no BDC positions directly.

For accredited investors building an income-oriented allocation, publicly traded BDCs offer private credit economics with exchange liquidity and full SEC disclosure. That combination justifies meaningful allocation. It does not justify ignoring the leverage, the non-accruals, or the lesson from Apollo's gate.
