What Is a Business Development Company (BDC)? The 2026 Census

The three rules that make a fund a BDC

A BDC is not a product type a sponsor invents; it is a legal election. The fund files Form N-54A with the SEC, and from then on the BDC sections of the 1940 Act apply to it instead of most of the rules for ordinary closed-end funds. In exchange for lighter rules, it accepts three constraints that decide what you own:

Equus Total Return, a listed BDC, says it plainly in its June 2026 10-Q: “qualifying assets must represent at least 70% of the total assets at the time of acquisitions of any non-qualifying.” Nothing in any of these rules requires a BDC's shares to trade on an exchange, which is why three very different products share the label.

How many BDCs exist: the October 2026 census

The SEC publishes the XBRL financial data from every BDC filing as monthly BDC Data Sets. We took the latest 10-Q or 10-K of every filer in the March to September 2026 sets (187 filers), dropped the six that stopped reporting before June because they withdrew their election or deregistered, and sorted the rest from their EDGAR records: listed if EDGAR shows an NYSE or Nasdaq listing, non-traded if not listed and it has filed a Form 424B prospectus or a Schedule TO-I tender offer since January 1, 2025, private if neither. It is the same rule as our non-traded BDC list, and the non-traded and private totals match it to the dollar.

Counts, sums and medians are our arithmetic; one accession per fund in sources/sec_bdc_census_extract.txt.

Three things in that table matter more than the totals. First, the typical BDC dollar is no longer on an exchange: non-traded BDCs hold 61.6% of all BDC net assets and 2.2 times the net assets of listed ones (our arithmetic). Second, the biggest BDC is a non-traded fund: Blackstone Private Credit Fund reports $81.29B of total assets and $42.78B of net assets, against $30.50B and $13.89B for Ares Capital, the largest listed BDC. Third, "private BDC" is a real category, not a marketing phrase: 61 funds with $28.79B of net assets that raise money from a few institutions or wealthy investors through capital calls; the largest by net assets are Diameter Credit Co ($1.50B), APS BDC ($1.43B) and Stone Point Credit Corp ($1.38B). If you came here looking for a list, the listed ones are in our BDC stocks list and the non-traded ones, with NAV and leverage, in the non-traded BDC list.

Where BDCs come from, and where they go

A fund becomes a BDC by filing Form N-54A and stops being one by filing Form N-54C. Counting both in EDGAR's full-text search shows the pace of the private credit build-out:

Source: EDGAR full-text search (efts.sec.gov), form-type filter, one query per calendar year, retrieved October 9, 2026. 2026 has 16 N-54A filings from 14 distinct filers. Totals are our arithmetic: 162 elections and 63 withdrawals since 2019.

The eight 2026 withdrawals: Redwood Enhanced Income Corp. filed its N-54C on February 27, 2026, Monroe Capital Corp on April 14, Nuveen Churchill BDC V on May 12, X1 Capital on June 17, Venture Lending & Leasing IX on July 22, the Investcorp US Private Credit BDC II liquidating trust on August 13, Firsthand Technology Value Fund on August 18 and Manulife Private Credit Fund on September 30. The newest election on file is Third Point Private Capital Income Fund's, on October 1, 2026.

What a BDC costs: the fee terms in six filings

A BDC pays its external adviser twice: a base management fee on assets, and an incentive fee on income above a hurdle (plus a fee on realized capital gains). Non-traded funds add distribution fees on some share classes. The rates are written in each 10-Q:

Source: each fund's Form 10-Q for June 30, 2026: Blackstone Private Credit Fund 0001803498-26-000048, Blue Owl Credit Income Corp. 0001812554-26-000047, Ares Capital 0001628280-26-050307, Blue Owl Capital Corp 0001655888-26-000056, FS KKR Capital 0001628280-26-053783, Diameter Credit Co 0001193125-26-342470.

The headline rates hide the base. A 1.25% fee on net assets and a 1.5% fee on gross assets are not close: a listed BDC with $1.26 of liabilities per $1 of equity charges its fee on borrowed money too. That is visible when you add up what the funds actually booked in the quarter:

Source: SEC BDC Data Sets (XBRL tags ManagementFeeExpense, IncentiveFeeExpense or its income and capital-gains parts, and fee-waiver tags, quarter ended June 30, 2026). Sums and medians are our arithmetic; the annual rate is the quarter's fee times four over quarter-end net or total assets. Internally managed BDCs, such as Main Street, do not book a management fee and are not in the medians. Base fees are as tagged; some funds show a waiver separately.

Two readings. At listed BDCs, the base fee per dollar of shareholder equity is more than twice the non-traded median, because it is charged on gross assets. At non-traded BDCs, the incentive fee is the bigger surprise: $564.1M against $586.4M of base fees, 96% as large (our arithmetic). Blackstone Private Credit Fund booked $142.1M of base fee and $143.1M of incentive fee in the quarter; Blue Owl Credit Income Corp. $60.4M and $60.8M. A 5% hurdle is easy to clear when loans yield well above it, so in practice the investor pays both.

How much a BDC may borrow: the 150% test in practice

Asset coverage is total assets, less liabilities other than debt, divided by debt. At 150% a BDC can carry $2 of debt for every $1 of equity; at the old 200% the limit was $1. Blackstone Private Credit Fund's 10-Q states the test in one sentence: “the Company is allowed to borrow amounts such that its asset coverage, as defined in the 1940 Act, is at least 150% after such borrowing.” It reports $35.3 billion of debt and an asset coverage ratio of 221.3% at June 30, 2026.

Across the census, 79 BDCs tag a usable asset coverage ratio in XBRL; the median is 196.2% (our arithmetic). The lowest tagged figures are CION Investment Corp at 157%, WTI Fund XI at 160% and MidCap Financial Investment Corp at 163%. One listed BDC reports below the line in its text rather than its tags: Investcorp Credit Management BDC says “our asset coverage for borrowed amounts was 145.2%” at June 30, 2026. Being under 150% does not force a sale; it means the BDC may not issue new senior securities until coverage is back at 150% after the issuance. Our BDC stocks list gives the asset coverage of each listed BDC.

The simpler measure, total liabilities over net assets, puts the median listed BDC at 1.26, the median non-traded BDC at 1.03 and the median private BDC at 0.96 (our arithmetic). Liabilities include payables, so the ratio slightly overstates borrowing.

Getting out: market price, tender offer, or waiting

The kind of BDC decides your exit far more than the loans inside it.

• Listed: you sell on the exchange at whatever the market pays, which can be far below NAV; the fund owes you nothing.
• Non-traded: you ask the fund to buy your shares in its quarterly tender offer, usually capped at 5% of shares outstanding. When more holders ask than the cap allows, everyone is cut back pro rata.
• Private: you committed capital for the fund's life; there is no regular window.

By our October 6, 2026 review of every non-traded BDC's latest Schedule TO-I/A, 15 of the 66 prorated, and those 15 hold $113.17B, 64.6% of non-traded net assets (our arithmetic from the census above). The five largest were all among them:

Source: each fund's final Schedule TO-I/A. Blue Owl Credit Income's filing gives tendered shares by class (72,307,451 S, 12,816,225 D, 310,304,828 I) and states 26.6%.

Two details from those filings change the cash you receive. Apollo Debt Solutions paid with “non-interest bearing, non-transferable promissory notes” settled on or about July 31, 2026, six weeks after its offer closed; BCRED also paid by promissory note, on or about July 29, and its payment was “less the early repurchase deduction, as applicable.” The other ten funds that prorated, from BlackRock Private Credit Fund (95.2% paid) to Onex Direct Lending BDC Fund (7.38%), are in the dataset and in the private credit redemptions tracker.

What a holder can do with this

• Know which of the three you own. The prospectus or subscription documents say whether shares are listed, sold continuously at NAV, or called as capital. That one fact decides your exit.
• Turn the fee into dollars. Multiply the base rate by the base it is charged on (net or gross assets), then add the incentive fee the fund actually booked last quarter; in the median non-traded BDC the incentive fee was about the same size as the base fee.
• Read the last tender result before you add money. A non-traded BDC that prorated last quarter can do so again; the result is in a Schedule TO-I/A on EDGAR, filed a few weeks after each offer.
• Watch asset coverage, not just the yield. A fund near 150% has little room to borrow more if loans go bad or holders ask for their money.
• Remember the 90% rule. Distributions are required, so a high payout is the structure working, not proof of performance; check whether net investment income covers it in the fund's 10-Q.
