The complete guide to BDCs

Q: Why are BDC yields so high?

Three things stack up. The loans themselves yield roughly 10–12%, because middle-market borrowers pay a premium for private capital, flexibility and speed. Leverage of around 1.1× amplifies that. And the 90% distribution rule means the income cannot be retained. The yield is a function of credit risk plus leverage, and it prices exactly what it looks like.

Q: Are BDC dividends qualified dividends?

Generally no. Because the income is mostly interest, distributions are ordinary income taxed at your marginal rate. Unlike REIT dividends, BDC ordinary distributions do not currently qualify for the 20% Section 199A deduction. For a US taxpayer in a high bracket, the combined federal rate can reach 40.8% including the net investment income tax, which is why many investors hold BDCs in tax-sheltered accounts.

Q: What is the single most important BDC metric?

Net asset value per share over time. Every other number can be flattered for a while. A BDC that has paid a 10% dividend for a decade while NAV per share fell from $20 to $12 delivered a far worse result than the yield implies, because roughly a third of your capital funded your own income.

Q: What does a 150% asset coverage ratio actually permit?

It permits two dollars of debt for every dollar of net assets. Asset coverage is total assets less non-debt liabilities, divided by total debt, and it must stay at or above 150%. Most listed BDCs run well inside that limit, around 0.9× to 1.25× debt to equity, because breaching it forces asset sales at the worst possible moment.

Q: What is PIK income and why does everyone worry about it?

Payment-in-kind interest is added to the loan balance instead of being paid in cash. It's taxable income the BDC must distribute, which means the fund pays out cash it never received. Some PIK is contractual and benign, common in growth lending. PIK that appears after a covenant breach is a borrower buying time, and the rate of change matters more than the level.

Q: Should I buy a BDC trading below NAV?

Sometimes the discount is the opportunity and sometimes it's the market's estimate of losses the marks haven't caught up with yet. The way to distinguish them is credit history: if the adviser's cumulative realised losses are low across a full cycle and non-accruals are under 2%, a discount is more likely to be sentiment. If losses have been chronic, the discount is a forecast.

Q: Are non-traded BDCs safer because they don't move?

No. They hold the same loans. What differs is that the price is set monthly by appraisal rather than continuously by the market, which smooths the reported path without changing the underlying risk. In exchange you accept a repurchase programme that is typically capped near 5% of NAV per quarter and can be limited when many investors head for the exit at once.

Q: What happens to a BDC when interest rates fall?

Roughly 90% of BDC assets are floating rate, while a good part of the liabilities is fixed-rate unsecured notes. Falling base rates therefore cut investment income faster than they cut funding costs, and NII compresses. The offset is that lower rates ease pressure on borrowers, so credit improves. The order matters: earnings fall first, credit relief arrives later.

Q: How is a BDC different from a high-yield bond fund?

A high-yield fund owns traded bonds with daily prices and no leverage at the fund level. A BDC originates its own private loans, holds them to maturity, marks them by model each quarter, and uses about 1.1× leverage. The BDC usually sits higher in the capital structure with tighter covenants, and it carries far less price transparency and a much heavier fee load.

A business development company is private credit wrapped in a listed security. Congress built the structure in 1980 so ordinary investors could finance private American businesses, and the result is a vehicle with bank-like economics, fund-like fees, and a yield that tells you exactly how much risk you're taking.

Foundations

What a BDC actually is

A business development company is a closed-end investment company that has elected to be regulated under sections 54 to 65 of the Investment Company Act of 1940. It raises permanent capital from public investors, borrows against it, and lends the proceeds to private companies that are too small for the bond market and, increasingly, no longer welcome at banks.

Almost every BDC also elects to be taxed as a regulated investment company, which removes entity-level tax on distributed income in exchange for paying out at least 90% of it. That's the same basic bargain a REIT makes, applied to loans instead of buildings.

It is a lender

Most of the portfolio is senior secured first lien loans to companies with $25m to $150m of EBITDA, priced at a floating spread over SOFR. The BDC negotiates the documents itself rather than buying paper in the market.

It is a fund

Positions are marked to fair value every quarter, there's a NAV per share, and most BDCs pay an external adviser a management fee and an incentive fee. The accounting is investment-company accounting, not operating-company accounting.

It is a listed security

Listed BDCs trade all day and can sit at a substantial premium or discount to NAV. That gap is itself a variable management has to manage, because issuing shares below NAV is restricted by law.

“

Key takeaway

Read a BDC as a small, levered, publicly quoted bank whose loan book is marked to model every quarter. Your return is the net interest spread, minus fees, minus credit losses. Everything in this lesson is an attempt to measure those three things honestly.

Legislation

How the law got here

The BDC exists because the 1940 Act made public lending funds nearly impossible, and Congress decided in 1980 that small business needed the capital anyway.

Year	Event	What changed
1940	Investment Company Act	The framework that regulates pooled investment vehicles in the US. Its restrictions on leverage, affiliate transactions and illiquid holdings made it impractical for a public fund to lend to private companies.
1980	Small Business Investment Incentive Act	Congress amends the 1940 Act with sections 54 to 65, creating the BDC. The deal: accept a specific regulatory regime, and in exchange you may raise permanent public capital and lend it to private American businesses.
2008–2012	Post-crisis bank retreat	Basel III capital rules and the leveraged lending guidance push banks out of middle-market lending. BDCs and private credit funds fill the gap, and the asset class starts compounding.
2018	Small Business Credit Availability Act	The asset coverage requirement drops from 200% to 150%, effectively doubling permitted leverage from 1:1 to 2:1. Requires either a shareholder vote or approval by the independent directors with a one-year delay.
2020	Rule 2a-5	The SEC modernises fair value determination. Boards may designate the adviser as 'valuation designee' subject to oversight, with compliance required from September 2022. This is the rule governing how private loans get marked each quarter.
2021 onward	The perpetual non-traded wave	Large alternative managers launch continuously offered, non-traded BDCs sold through wealth channels. This segment now holds more assets than the entire listed BDC market.
Today	A $500bn+ asset class	BDC gross assets have passed $500 billion, split roughly between listed vehicles near $180 billion of AUM and non-traded vehicles above $300 billion, inside a US private credit market that crossed $2 trillion in 2025.

The 2018 leverage change is still the biggest fault line

Doubling permitted leverage from 1:1 to 2:1 was sold as a way to fund more small business lending, and it also doubled the sensitivity of NAV to credit losses. Most BDCs did not go straight to the limit, settling around 1.0–1.25× debt to equity. But the ceiling matters in a downturn: a BDC running near the limit that suffers marks has to sell assets into a falling market to stay compliant.

Compliance

The rulebook a BDC lives under

Rule	Source	What it means in practice
70% qualifying assets	Section 55	At the time of any acquisition, at least 70% of total assets must be qualifying assets: securities of eligible portfolio companies acquired privately, plus cash, government securities and short-dated high-grade paper. The remaining 30% is the flexible bucket for broadly syndicated loans, foreign issuers and joint ventures.
Eligible portfolio company	Section 2(a)(46) + Rule 2a-46	A US-organised operating company that is either unlisted, or listed with a public equity market value below $250 million, or controlled by the BDC with a board seat. This is what keeps a BDC pointed at private middle-market businesses.
Significant managerial assistance	Section 2(a)(48)	A BDC must offer meaningful managerial help to the companies it finances. In practice this is a light obligation, satisfied by board observation rights and advisory availability.
Asset coverage	Section 61	Default 200% coverage, meaning debt no greater than equity. Since 2018 a BDC may elect 150% coverage, allowing up to two dollars of debt for each dollar of net assets, after board or shareholder approval.
Issuing below NAV	Section 63(2)	A BDC generally cannot sell new shares below net asset value per share without annual shareholder authorisation plus specific board findings. This is the single most important shareholder protection in the structure.
Board independence	Section 56	A majority of directors must not be 'interested persons' of the adviser. Those independent directors also approve the advisory agreement annually and oversee valuation.
Fair value	Rule 2a-5	Investments without readily available market quotations must be fair-valued in good faith each quarter, with a documented process, and usually third-party valuation input on a rotating basis.
Affiliate transactions	Sections 57	Co-investment alongside other funds run by the same adviser requires SEC exemptive relief and a compliant allocation policy. Nearly every large platform has this relief.

Asset coverage

Asset coverage = (Total assets − liabilities other than debt) ÷ Total debt ≥ 150%

150% coverage means debt can reach twice net assets. At 200% (the pre-2018 default and still the choice of a few conservative BDCs), debt cannot exceed net assets.

What a covenant breach looks like from the outside

Falling below the asset coverage floor stops a BDC from paying dividends on its common shares and from taking on new debt. Because credit marks fall and debt stays fixed, coverage deteriorates fastest exactly when selling assets is most expensive. This is the mechanism behind most permanent BDC capital destruction, and it's why the gap between current leverage and the regulatory limit is worth watching more closely than the leverage level itself.

◆Analyst note

SBIC subsidiaries are a quiet detail worth knowing. A BDC with a Small Business Investment Company licence can borrow SBA debentures at attractive fixed rates, and with SEC exemptive relief that debt sits outside the asset coverage calculation. It's genuinely cheap leverage, and it's also leverage that doesn't appear in the headline ratio.

Your side of it

RIC status, and what lands on your tax return

Electing regulated investment company status under Subchapter M is what makes the whole thing work. The requirements are a source-of-income test, a diversification test, and a distribution test.

Requirement	Detail
90% income test	At least 90% of gross income from dividends, interest, gains on securities and similar passive sources. Easy for a lender to satisfy.
Diversification test	At the end of each quarter, at least 50% of assets in positions where no single issuer exceeds 5% of assets and 10% of voting securities, and no more than 25% of assets in any one issuer.
90% distribution test	Distribute at least 90% of investment company taxable income each year, or lose pass-through treatment entirely.
4% excise tax	Separate from the above. Applies unless the BDC distributes 98% of ordinary income for the calendar year and 98.2% of capital gain net income, plus any prior undistributed amounts.
Spillover income	Taxable income earned but not distributed carries forward. Advisers deliberately keep a spillover buffer, and disclose it per share, because it lets them defend a dividend through a weak quarter.

How you're taxed as a US individual

Ordinary income dividends. Most of the distribution. Taxed at your marginal rate, and unlike REIT dividends they do not qualify for the 20% Section 199A deduction. Add the 3.8% net investment income tax above the thresholds and the top federal rate reaches 40.8%.
Qualified dividends. A small slice, from equity positions that pay corporate dividends.
Long-term capital gain distributions. When the adviser realises gains on equity stakes or debt bought at a discount.
Return of capital. When distributions exceed taxable income. Not taxed now, reduces your basis, and often a sign the dividend is running ahead of earnings.

The characterisation only arrives in January

The split between ordinary income, capital gain and return of capital is determined after year end. A BDC that paid what looked like a fully covered dividend all year can report a return-of-capital component in its 1099. Non-US holders face 30% withholding on ordinary dividends unless a treaty or the interest-related dividend designation reduces it, and not every BDC makes that designation.

The portfolio

What's actually inside a BDC

Instrument	Position in capital structure	Typical yield	What to know
First lien / unitranche	Top. Secured by all assets	SOFR + 450–650bp	The bulk of most modern portfolios. Unitranche blends first and second lien into one instrument at a blended spread, often with a first-out tranche sold to a bank.
Second lien	Behind first lien	SOFR + 700–900bp	Much higher loss severity in default. Largely out of fashion since 2022, but it lingers in older vintages.
Subordinated / mezzanine	Below all secured debt	10–14%, often part PIK	Frequently paired with warrants. Real equity-like risk with debt-like documentation.
Preferred and common equity	Bottom	n/a	Co-investments alongside sponsors, or equity taken in restructurings. A rising equity share sometimes means past loans went wrong.
Joint ventures	Off to the side	Distribution yield 12–15%	An unconsolidated vehicle, usually holding syndicated loans with its own leverage. Look through to what the JV owns and how levered it is.
Broadly syndicated loans	Top, but liquid and public	SOFR + 300–400bp	Lives in the 30% non-qualifying bucket. Lower yield, better liquidity, sometimes used as a place to park capital.

Middle market, by size

Borrower size is the strongest single predictor of loss rates, and it's the cleanest way to compare two BDCs whose loan books otherwise look identical.

Lower middle marketEBITDA under $25m

Core middle marketEBITDA $25m–$75m

Upper middle marketEBITDA $75m–$150m

Large / broadly syndicated territoryEBITDA above $150m

Lower middle market lending earns 150–250bp more, and it's a genuinely different business: fewer buyers if things go wrong, thinner management teams, and much greater dispersion of outcomes. Neither end of the range is inherently better, but paying a premium multiple for a lower-middle-market book on the assumption it behaves like an upper-middle-market book is a common mistake.

Read the covenant package

Ask whether loans carry maintenance covenants, tested every quarter, or are covenant-lite. Maintenance covenants get the lender to the table early, while the borrower still has value to negotiate over. Most middle-market direct lending keeps them, and most upper-market deals have lost them. It's one of the strongest arguments for the smaller end of the market.

Mechanics

How a BDC earns, line by line

Line	What it is	What to watch
Interest income	Cash coupon on loans, usually SOFR plus a spread of 450–650bp on first lien	The core. Rises with base rates, falls when they cut.
PIK income	Interest paid in more principal instead of cash	Taxable and distributable, but no cash arrives. A rising PIK share is the most reliable early stress signal in the sector.
Fee income	Origination, amendment, prepayment and structuring fees	Lumpy. Boosts a quarter's NII without being repeatable, so strip it out when assessing run-rate earnings.
Dividend income	From equity stakes and joint venture vehicles	Often from an unconsolidated JV holding syndicated loans. Check what the JV itself is levered at.
Interest expense	Cost of the BDC's own borrowings: revolvers, unsecured notes, CLOs, SBA debentures	Watch the fixed-versus-floating mix on the liability side against the floating asset side.
Base management fee	Typically 1.0–1.75% on gross assets	Charged on gross assets means the adviser is paid on borrowed money too.
Incentive fee	Usually 15–20% of income above a hurdle, plus a capital gains component	The part that most investors never model. Worked through below.

The whole income statement, compressed

NII = Total investment income − interest expense − base fee − incentive fee − other opex

Then: net increase in net assets = NII + net realised gains/losses + net change in unrealised appreciation. NII pays the dividend. The gain and loss lines move NAV.

Worked example

A $1bn BDC at 1.0× leverage

Net assets$1,000M

Debt at 1.0× leverage$1,000M

Gross assets$2,000M

Portfolio yield 11.0%$220M

Interest expense at 6.0% on debt($60M)

Base management fee, 1.5% of gross assets($30M)

Other operating expenses($12M)

Pre-incentive-fee NII$118M

Incentive fee at 17.5% (hurdle cleared)($20.7M)

Net investment income$97.3M

NII return on net assets9.7%

Now the part that surprises people. Total fees were $50.7m against $1,000m of net assets, a drag of 5.1% on shareholder equity before a single loan goes bad. The portfolio had to earn 11% for you to receive 9.7%, and that's in a good year with no credit losses at all.

Now add one bad quarter

Suppose 3% of the portfolio at cost goes on non-accrual and is marked at 60 cents. Income falls by roughly $6.6m and unrealised depreciation of about $24m hits NAV. NII drops to around $91m, still covering a 9% dividend, while NAV per share falls 2.4%. Reported earnings barely moved. Your capital did. This asymmetry between the income statement and NAV is the central thing to understand about BDC investing.

Costs

The fee stack, in detail

Most BDCs are externally managed, and the fee agreement is the most consequential document in the filing set. Four components, and each has variants that matter.

Component	Typical terms	What to check
Base management fee	1.0–1.75% per year, usually on average gross assets	Whether the basis is gross or net assets. On gross assets, borrowing more raises the fee even if the spread earned is zero. Some newer BDCs charge on net assets, which is materially better aligned.
Income incentive fee	15–20% of pre-incentive NII above a hurdle of 1.5–1.75% per quarter (6–7% annualised)	The hurdle is calculated on net assets, so leverage helps the adviser clear it. Check whether the hurdle floats with base rates or is fixed.
Catch-up	100% of income between the hurdle and a catch-up threshold goes to the adviser	Above the hurdle, the adviser takes everything until it has received its full percentage of all pre-incentive NII. The marginal fee rate in this band is 100%, which is why 'above the hurdle' means less than it sounds.
Capital gains incentive fee	15–20% of cumulative realised gains net of realised losses and unrealised depreciation	Cumulative and netted since inception, so it should not be payable while the portfolio is underwater.
Total return lookback	Caps the income fee if total return over a trailing 12 quarters is negative	Present in better-structured BDCs, absent in weaker ones. Without it, the adviser can earn income fees while shareholders lose capital.
Non-traded add-ons	Shareholder servicing fees of 0.25–0.85% per year, sales loads, early repurchase deductions of about 2%	These sit on top of everything above and are the main reason non-traded vehicles cost more.

The catch-up, made concrete

Hurdle 1.75%/qtr · Incentive 17.5% · Catch-up threshold ≈ 2.1212%/qtr

Below 1.75% the adviser gets nothing. Between 1.75% and 2.1212% it takes 100% of the increment. Above that it takes 17.5%. So going from a 1.74% quarter to a 2.12% quarter transfers the entire improvement to the adviser.

Internally managed BDCs

A small number of BDCs employ their own investment teams and report costs as operating expenses instead of paying an adviser. Their total expense ratios are often 100–200bp lower, and they have historically traded at premiums to NAV for exactly that reason. The structure is rare because launching one requires an existing team willing to give up adviser economics.

The scoreboard

NAV per share is the whole story

NAV per share is the fair value of the investments plus cash, less debt and other liabilities, divided by shares outstanding. Because a BDC is a fund, this number is meaningful in a way that book value at an operating company is not.

Total NAV return — the honest performance measure

Total NAV return = (Ending NAV/share − Beginning NAV/share + dividends paid) ÷ Beginning NAV/share

Compute it over three and five years. It captures income and capital together, and it's immune to the optical appeal of a big yield.

What moves NAV

Credit marks. Quarterly fair value changes on the loan book, usually the largest driver.
Over- or under-earning the dividend. Paying more than NII slowly grinds NAV down, quarter after quarter.
Share issuance. Issuing above NAV is accretive to NAV per share. Issuing below is dilutive, which is precisely why it needs shareholder approval.
Realised losses. When a marked-down loan is finally resolved, unrealised depreciation converts to a realised loss. NAV doesn't move at that moment, but the loss becomes permanent and appears in the cumulative record.

Marked to model, not to market

Private loans have no observable price. Under Rule 2a-5 the board, or a designated valuation designee, determines fair value each quarter using discounted cash flow, comparable yields and enterprise value coverage, typically with third-party input on a rotating basis. The process is genuine and it's still an estimate produced by a party with an incentive for the number to be high. Treat a NAV that never moves in a volatile credit market with the same scepticism you'd apply to a hedge fund reporting eleven consecutive positive months.

Reference

The analyst dashboard

Everything here comes from the 10-Q, the 10-K or the quarterly earnings supplement. Track it for eight quarters and the trajectory tells you more than any single reading.

Metric	What it measures	What good looks like
NAV per share	Net assets divided by shares outstanding	Flat to rising over a full credit cycle
Total NAV return	Change in NAV per share plus dividends paid, over opening NAV	The only honest performance measure. Compare over 3 and 5 years
NII per share	Net investment income before realised and unrealised marks	Comfortably above the regular dividend
Dividend coverage	NII per share ÷ regular dividend per share	Above 1.0×, ideally 1.05–1.20× on the base dividend
Non-accruals (% of cost)	Loans no longer accruing interest, at original cost	Under 2%. Above 4% needs a specific explanation
Non-accruals (% of fair value)	Same loans at current marks	Always lower than at cost. A wide gap shows how much has already been written down
PIK as % of total investment income	Non-cash interest share	Under 10%. Above 15% and rising is a warning
Weighted average yield at cost vs fair value	Portfolio yield on two bases	A yield at fair value far above cost means marked-down loans are flattering the yield
First lien %	Share of portfolio in senior secured first lien	Above 70% for a defensively positioned book
Number of portfolio companies	Diversification	Above 100 for a large BDC; check the top-10 concentration too
Weighted average portfolio EBITDA	Size of the borrowers	Larger borrowers default less. Under $30m EBITDA is genuinely small-cap credit
Portfolio interest coverage	Borrower EBITDA ÷ borrower interest expense	Above 2.0× is healthy. Approaching 1.0× across the book is a sector-level alarm
Net leverage	Debt less cash, divided by net assets	0.9–1.25× is the current norm. Above 1.4× leaves little room for marks
Unsecured debt %	Share of liabilities that is unsecured	Higher is better. Unsecured bonds don't margin-call you
Liquidity vs unfunded commitments	Cash and undrawn revolver against delayed-draw obligations	Coverage above 1.5× of unfunded commitments
Spillover income per share	Undistributed taxable income carried forward	A buffer that can support the dividend for a quarter or two
Cumulative net realised losses since inception	Total credit losses actually crystallised	The single best test of an adviser's underwriting. Rarely quoted, always available
Share count growth vs NAV per share	Whether issuance helped or hurt	Share count can grow only if NAV per share does not fall

The payout

How BDC dividends are actually structured

Most BDCs now run a two-part payout, and understanding the split changes how you read a dividend cut.

Base dividend

Set at a level management believes is sustainable through a downturn, typically 85–95% of expected NII in a normal environment. This is the number that matters. A cut here is a real signal.

Supplemental or variable dividend

A quarterly top-up, often a fixed share of the NII that exceeded the base. Designed to be cut without drama, and to release spillover income before the excise tax bites. Falling supplementals are normal in a rate-cutting cycle and are not the same as a dividend cut.

Special dividends appear when realised gains or accumulated spillover need to be distributed. They're a legal obligation dressed as generosity, and they should never be annualised into a yield.

Coverage below 100% isn't automatically a problem

A BDC with meaningful spillover income per share can pay above NII for several quarters entirely legitimately, because that income was already earned and taxed in a prior year. Check the spillover disclosure before concluding that a shortfall means a cut is coming. What is a problem is uncovered dividends with no spillover buffer and a falling NAV, which is the classic pattern before a reset.

Pricing

Valuing a BDC

Valuation here is simpler than in most of equity research, because the balance sheet is marked and the earnings are a spread. Three lenses do almost all the work.

Lens	How to use it	Where it misleads
Price to NAV	The anchor. Compare to the BDC's own five-year range and to peers with similar credit records. Quality platforms with low realised losses persistently trade at 0.95–1.20× NAV; weaker ones sit at 0.6–0.8×.	NAV itself is an estimate. A discount can be the market front-running marks that haven't happened yet.
Return on equity (NII ÷ NAV)	Tells you what the portfolio earns on your capital after all fees. Compare across BDCs to see who converts a similar loan book into more shareholder income.	One quarter of prepayment fees can inflate it. Use recurring NII.
Dividend yield on price vs NII yield on NAV	If the dividend yield on price far exceeds the NII yield on NAV, the market is pricing a cut or a loss. That gap is a forecast, not an opportunity.	Ignores spillover, which can legitimately fund a temporary gap.

The reflexive loop worth understanding

Premium to NAV → issue shares accretively → NAV/share rises → premium justified

It runs in reverse too. A BDC stuck at a discount cannot grow through issuance, so the value-creating move becomes buying back its own shares below NAV. Watch which one management chooses; it tells you whose interests are being served.

◆Analyst note

An adviser paid on gross assets has a structural preference for growing the fund. A board that authorises buybacks at a discount instead is choosing shareholders over adviser revenue. Over ten years, that single behavioural difference explains a large share of the return gap between the best and worst BDCs.

Macro

What interest rates do to a BDC

Around 90% of BDC assets carry floating rates tied to SOFR, most with an interest rate floor. The liability side is a mix: revolvers and CLO liabilities float, unsecured notes are usually fixed. That mismatch is deliberate, and it makes BDC earnings pro-cyclical with rates.

Dimension

Rates rising

Rates falling

Investment income

Rises almost immediately as loans reset quarterly.

Falls just as quickly. Floors provide a partial buffer only once base rates are very low.

Funding cost

Rises on floating debt, unchanged on fixed notes. Net effect is positive for NII.

Falls only on the floating portion, so NII compresses.

Borrower health

Interest coverage deteriorates. Companies levered at 5× EBITDA feel it within two quarters.

Net for shareholders

Earnings up now, credit risk building underneath.

Earnings down now, credit risk easing. Dividends usually get trimmed before the credit benefit shows up.

Pricing

Continuous market price, frequently at a discount or premium to NAV.

Monthly NAV set by the adviser under board oversight. Subscriptions and repurchases both happen at NAV.

Sell any trading day, at whatever the market offers.

Quarterly repurchase offer, typically capped near 5% of NAV, and reducible or suspendable by the board.

Base plus incentive plus shareholder servicing fees, and often an early repurchase deduction in the first year.

Leverage

Usually 0.9–1.25× debt to equity.

Often slightly lower, in the 0.6–1.0× range, to support the repurchase programme.

The honest trade

You see the market's opinion every day, including when it's ugly.

You get a smoother reported path and pay for it in fees and in the risk of gating precisely when you want out.

Non-traded doesn't mean uncorrelated

The loans in a perpetual non-traded BDC and the loans in a listed BDC are frequently originated by the same platform on the same terms. Reported volatility differs because appraisal-based pricing lags. The underlying risk does not differ, and anyone selling appraisal smoothing as diversification is describing a measurement artefact.

Risk

The risks that actually show up

Credit losses in a real recession

The asset class has grown enormously since 2010 without facing a deep, prolonged default cycle. Underwriting quality across the 2021 vintage, when spreads were tight and documents were loose, has not been fully tested.

Leverage working in reverse

At 1.2× leverage, a 10% decline in portfolio fair value takes 22% off NAV per share. The regulatory coverage test can then force selling into the same weak market.

Mark-to-model lag

Marks move slower than reality. Loans typically drift down over several quarters before hitting non-accrual, so a clean-looking non-accrual rate can coexist with a deteriorating book.

Fee drag compounding

Roughly 5% of net assets in annual fees is a permanent headwind. Over a decade that's a very large share of the gross spread the portfolio generates.

Adviser conflicts

The same platform often runs a listed BDC, a non-traded BDC and private funds, all competing for the same deals. Allocation policy exists, and the incentive to grow assets is constant.

Spread compression

A wall of private credit capital chasing a finite pool of borrowers pushes spreads down and covenants out. Lower yield for the same risk is a slow, quiet way to lose money.

Forensics

Eight red flags in a BDC

Signal	What it usually means
NAV per share grinding down every year	The dividend is being funded partly by capital. A BDC yielding 12% while NAV falls 4% a year is returning about 8%, and the market usually notices before the press release does.
PIK income rising faster than cash interest	Borrowers are being allowed to defer cash payments. This shows up as strong reported NII right up until the loan goes on non-accrual.
Repeated amendments and 'amend and extend'	Restructurings that keep a loan technically performing. Check the schedule of investments for maturity dates being pushed out and coupons being converted to PIK.
Yields far above peers on similar-looking loans	Either the borrowers are much smaller and weaker, or the loans sit lower in the capital structure. Read the schedule of investments and check the attachment points.
Equity issued below NAV	Legal only with shareholder approval, and immediately dilutive to existing holders. Look for it in the proxy each year.
Base fee on gross assets with no expense cap	Every extra dollar of borrowing raises the fee whether or not it earns a spread. Combined with a low hurdle this misaligns the adviser badly.
Incentive fee with no total-return lookback	The adviser collects on income while the portfolio loses capital. A lookback ties the fee to net cumulative results, and its absence is a genuine structural weakness.
Concentration in one sector or sponsor	Software and healthcare services dominate many portfolios. A single private equity sponsor across 15 positions is a correlated exposure, not diversification.

Process

The 12-step BDC workflow

Step	Action	Why
1	Pull the last eight quarters of NAV per share	Before anything else. The trend answers the only question that matters: is the adviser preserving capital while paying you?
2	Compute total NAV return over three and five years	Change in NAV per share plus dividends, divided by opening NAV. Compare to peers and to a leveraged loan index.
3	Read the earnings supplement, not the press release	Non-accruals, PIK share, yields at cost and fair value, portfolio company count, and the leverage ratio all live there.
4	Check dividend coverage on regular NII	Strip out one-off fee income and prepayment fees. Ask whether the base dividend survives on recurring interest alone.
5	Open the schedule of investments	It's tedious and it's where the truth is. Scan for PIK notation, maturity dates inside 18 months, and positions marked far below cost.
6	Count the loans marked under 90 cents	These are tomorrow's non-accruals. Compare the count to two quarters ago.
7	Read the fee agreement in the 10-K	Base rate and whether it's on gross or net assets, hurdle rate, catch-up mechanics, incentive rate, and whether a total-return lookback exists.
8	Model the fee drag on net assets	Add the base fee and incentive fee, then divide by average net assets. Anything above 4% is a high bar for the portfolio to clear.
9	Map the liability side	Maturity by year, fixed versus floating, secured versus unsecured, and covenant headroom on the revolver.
10	Check cumulative realised losses since inception	Usually disclosed in the annual report or investor deck. It separates skilled underwriters from those who have been lucky in a benign cycle.
11	Compare price to NAV against the five-year range	And ask what has changed to justify today's level, rather than assuming reversion.
12	Write the bear case in one paragraph	Name the recession scenario, the non-accrual rate it implies, and what that does to NAV and to the dividend. If you can't, you're buying a yield you don't understand.

Key takeaway

If you only ever do two of these: plot NAV per share for eight quarters, and read the fee agreement. Those two alone eliminate most of the BDCs that look attractive on a yield screen and shouldn't.

Comparison

BDC versus REIT

The two structures rhyme: both escape entity-level tax by distributing at least 90% of taxable income, both are therefore high-yield by design, and both must return to the capital markets to grow. What they own could hardly be more different.

Dimension

REIT

BDC

Underlying asset

Buildings, and the leases attached to them.

Private company loans, mostly senior secured and floating rate.

Governing law

Internal Revenue Code sections 856–860.

Investment Company Act sections 54–65, plus Subchapter M for tax.

Earnings metric

FFO, then AFFO. Net income is distorted by depreciation.

Net investment income. There is no depreciation to worry about.

Balance sheet metric

Net asset value, estimated from cap rates on NOI.

Net asset value, marked quarterly under Rule 2a-5.

Leverage limit

No statutory cap. Market discipline via ratings, typically 5–6.5× net debt/EBITDAre.

Statutory: 150% asset coverage, so a hard ceiling near 2:1 debt to equity.

Rate sensitivity

Mostly fixed-rate debt against long leases. Rate moves hit the cost of capital and asset values.

Floating assets against partly fixed debt. Earnings move with base rates within two quarters.

Inflation behaviour

Escalators and short leases give partial protection. Long fixed-bump net leases don't.

Floating rates track policy rates, which track inflation with a lag. Indirect protection.

Tax on dividends (US)

Ordinary portion gets the 20% Section 199A deduction. Some return of capital.

Ordinary income at full marginal rates. No 199A deduction.

Fee structure

Mostly internally managed, G&A around 30–60bp of assets.

Mostly externally managed, all-in fees frequently near 5% of net assets.

What kills you

A cap rate reset combined with a refinancing wall.

A default cycle combined with leverage near the regulatory limit.

Frequently asked questions

What is a BDC in one sentence?＋

A publicly regulated fund that lends to private American companies, must distribute at least 90% of its taxable income to avoid entity-level tax, and can borrow up to about twice its net assets to do it. Think of it as a private credit fund you can buy on an exchange.
