Business development companies, or BDCs, are publicly regulated investment funds that pool shareholder money to lend to and take equity stakes in small and mid-sized private companies. They trade mostly like stocks, pay out nearly all their income as dividends, and offer retail investors access to private-credit deals that would otherwise be out of reach. That access comes with real credit risk, leverage, and, for many BDCs, a management-fee structure worth reading closely before you buy.
Congress created the BDC framework in 1980 to channel capital toward businesses that struggle to get traditional bank financing or reach public markets. A company becomes a BDC by electing that status with the SEC under 15 U.S.C. § 80a-53 and registering a class of equity securities under the Securities Exchange Act.1Office of the Law Revision Counsel. 15 USC 80a-53 – Election to Be Regulated as Business Development Company Most also elect to be treated as Regulated Investment Companies under Subchapter M of the tax code, which lets them skip corporate-level income tax as long as they meet strict distribution and diversification rules.2Office of the Law Revision Counsel. 26 USC 851 – Definition of Regulated Investment Company
What a BDC Actually Owns
Federal law requires at least 70% of a BDC’s total assets to sit in qualifying investments, often called the 70% basket. Only the remaining 30% can go elsewhere.3FINRA. FINRA Adopts Exemption From FINRA Rules 5130 and 5131 for Business Development Companies The qualifying bucket is made up mainly of securities bought in private transactions from eligible portfolio companies, securities of companies the BDC already controls, and securities of financially distressed companies acquired privately.4Securities and Exchange Commission. Final Rule – Definition of Eligible Portfolio Company Under the Investment Company Act of 1940
An eligible portfolio company must be organized in the United States, cannot itself be an investment company, and has to meet at least one size-related test. The most common qualifier is that the company’s securities are not eligible for margin lending, which in practice means private businesses or very small public ones. Alternative tests include total assets of $4 million or less (with at least $2 million in capital), or being controlled by the BDC.5Office of the Law Revision Counsel. 15 USC 80a-2 – Definitions
The investments themselves are usually senior secured loans, sitting at the top of the repayment hierarchy. Some BDCs also hold subordinated debt, warrants, or direct equity stakes for a piece of the upside if a borrower grows. Beyond writing checks, a BDC has to offer “significant managerial assistance” to its portfolio companies, meaning guidance on operations, management, or strategy that the borrower can accept if it wants.6Legal Information Institute. 15 USC 80a-2 – Making Available Significant Managerial Assistance In practice, this often shows up as board seats and hands-on financial advice.
Why BDC Yields Are High
To keep RIC tax status, a BDC has to distribute at least 90% of its investment company taxable income to shareholders each year. Miss that threshold and the pass-through treatment disappears entirely for the year, with the fund taxed at regular corporate rates on everything it earned.7Office of the Law Revision Counsel. 26 USC 852 – Taxation of Regulated Investment Companies and Their Shareholders
A separate calendar-year rule adds another push. If a BDC fails to distribute at least 98% of its ordinary income and 98.2% of its capital gain net income by year-end, it owes a 4% excise tax on the shortfall.8Office of the Law Revision Counsel. 26 USC 4982 – Excise Tax on Undistributed Income of Regulated Investment Companies Most BDCs time their quarterly distributions to steer clear of it. Between the 90% rule and the excise tax, almost everything a BDC earns has to flow out to shareholders. That’s the mechanical reason yields tend to run well above what you’d get from most publicly traded investments.
How BDC Dividends Are Taxed on Your Return
Because the fund pays no corporate tax, the tax bill lands on you. You’ll get a Form 1099-DIV early in the year showing how each distribution breaks down.9Internal Revenue Service. About Form 1099-DIV, Dividends and Distributions
Here is where BDCs part ways with typical dividend stocks. Most of a BDC’s income is interest on loans, not corporate earnings that have already been taxed. So the bulk of what you receive is taxed as ordinary income at your marginal rate, not at the lower qualified-dividend rate. A slice may qualify for the preferential rate if it came from equity holdings, and capital gain distributions from selling portfolio investments at a profit are taxed at long-term capital gains rates. Some distributions may be classified as return of capital, which reduces your cost basis instead of creating immediate taxable income.
One boundary worth flagging: for 2026, there is no Section 199A deduction available for BDC dividends. The pass-through deduction that applies to REIT dividends was not extended to BDCs when the One Big Beautiful Bill Act was signed into law in July 2025. If you’re comparing BDCs to REITs on an after-tax basis, that difference matters.
Leverage and What It Means for You
BDCs borrow money to amplify returns, and federal law caps how much. The baseline rule under 15 U.S.C. § 80a-18 requires at least $2 of assets for every $1 of debt, a 200% asset coverage ratio. If assets fall below that, the fund cannot pay dividends or take on new borrowings until it comes back into compliance.10Office of the Law Revision Counsel. 15 USC 80a-18 – Capital Structure of Investment Companies
The Small Business Credit Availability Act of 2018 lets BDCs cut that ratio to 150%, or $1.50 of assets per $1 of debt, with either majority shareholder approval or a two-thirds vote of independent directors plus disclosure requirements.11Congress.gov. 115th Congress – Small Business Credit Availability Act Many BDCs have adopted the lower floor. Extra leverage boosts returns when loans perform, but it cuts the other way too. Portfolio losses hit equity harder when there’s more debt in the stack, and a stressed BDC operating near the 150% minimum may be forced to sell loans at bad prices just to stay compliant.
Internal Versus External Management
BDCs run in two configurations. An internally managed BDC employs its own investment team, with compensation showing up as a line item on the income statement. Total expense ratios tend to be lower because no outside advisor is extracting a separate profit margin.
An externally managed BDC hires a third-party investment advisor. The advisor charges a base management fee, typically 1% to 2% of total assets per year, often calculated on gross assets including leverage. That’s a meaningful detail: the fee applies to borrowed money, not just shareholder equity. On top of the base fee, the advisor earns an incentive fee, usually split into an income-based component tied to net investment income and a capital gains component tied to realized profits.
The income-based incentive typically comes with a hurdle rate in the 6% to 8% annualized range. Below the hurdle, the advisor earns nothing extra. Once the fund clears the hurdle, a catch-up provision kicks in, handing the advisor 100% of returns in a narrow band above the hurdle until they’ve effectively earned their percentage on all income, not just the portion above the hurdle. Past the catch-up, the advisor typically takes 20% of remaining income. Read the prospectus carefully. The catch-up is where external fees can quietly consume a large share of returns in a merely decent year.
How to Buy BDC Shares
Publicly Traded BDCs
Most BDCs trade on the NYSE or NASDAQ. You buy and sell them through any standard brokerage account, just like common stock, with real-time pricing and full liquidity during market hours. This is the simplest path into private credit without locking up your money.
The share price on the exchange often differs from the fund’s net asset value per share. When the market price sits below NAV, you’re buying the loan portfolio at a discount; above NAV, you’re paying a premium. Persistent NAV discounts are common among BDCs and closed-end funds, and the gap can widen sharply during market stress. A large discount doesn’t automatically mean the shares are cheap. It may reflect the market’s view that the loan portfolio carries more credit risk than management’s marks suggest.
Non-Traded BDCs
Some BDCs don’t list on public exchanges. These non-traded funds are sold through financial advisors, often with higher upfront fees. Liquidity is severely limited. Most offer periodic share repurchase programs, typically quarterly and capped at around 5% of net asset value per quarter, and there’s no guarantee the fund will honor repurchase requests in full. Funds have suspended or reduced repurchases during periods of market stress. Treat a non-traded BDC as a long-term, illiquid commitment.
The Risks Behind the Yield
High BDC yields are compensation for real risks. Three of them concentrate the exposure.
Credit risk. BDCs lend to companies that can’t get cheaper bank financing, so the borrower pool is inherently riskier than an investment-grade bond fund. A Federal Reserve Bank of Boston stress-test simulation estimated that in a severely adverse economic scenario, the median BDC would lose roughly 16% of its portfolio assets, with assumed loss rates of about 15% on first-lien loans and nearly 20% on unsecured loans.12Federal Reserve Bank of Boston. Bank Capital and the Growth of Private Credit Those are modeled worst-case figures, not predictions, but they show the shape of the exposure.
Leverage risk. A BDC operating at the 150% asset coverage minimum has about $2 of investments for every $1 of equity, so portfolio losses hit equity disproportionately. In the same Fed simulation, the median BDC was estimated to cut lending by about 8% over six quarters of stress as it deleveraged, with one-quarter of BDCs reducing lending by nearly 20%. Forced selling during stress can lock in losses right when the portfolio needs time to recover.
Interest rate risk. Most BDC loans carry floating rates, so income rises when benchmarks climb. In moderate rate environments, that’s a benefit. When rates rise sharply, borrowers face ballooning interest costs on their existing debt, which raises default risk. The same feature that boosts income in normal times can accelerate credit losses during a rate shock, especially for BDCs that carry fixed-rate debt on the liability side while their portfolio income swings.
Fee drag. An externally managed BDC with a 1.5% base fee and a 20% incentive fee above a 7% hurdle might pay out 3% to 4% of gross assets in management costs during a decent year. Because those fees are calculated on total assets including leverage, shareholders effectively pay fees on borrowed money. In a modest-return year, the fee structure can consume a large portion of what would otherwise reach investors as dividends.
