NII Coverage Ratio: Is a BDC Dividend Really Covered?
NII coverage is the opening test for a BDC dividend. Cash quality, credit and the recurring payout determine whether the cushion deserves trust.
Last updated: September 27, 2026.
NII coverage ratio equals net investment income per share divided by distributions per share. A ratio of 1.10x means the BDC earned $1.10 of NII for every $1.00 it distributed.
NII coverage ratio = NII per share ÷ distributions per share
That is the calculation. The harder question is whether the income is recurring, collected in cash, and strong enough to survive weaker credit conditions.
NII coverage ratio in one screen
| Coverage | Plain-English meaning | First investor question |
|---|---|---|
| Below 1.00x | NII did not fully cover distributions | What filled the gap? |
| 1.00x to 1.10x | Covered, but with a thin cushion | Can coverage survive lower fees or higher funding costs? |
| 1.10x to 1.20x | Healthier reported cushion | Is the income recurring and collected in cash? |
| Above 1.20x | Strong reported coverage | Is the strength durable or unusually boosted by fees, rates, or PIK? |
A single quarter can be noisy. The trend matters more than one reading.
Calculate the cushion, then test it
The Drift · Dividend cushion desk
Coverage can look sturdy before the cash does
Start with reported Net Investment Income, separate the regular and supplemental payouts, then test how non-cash income and a weaker quarter change the cushion.
Read the cushion in layers
Read: Reported NII covers the total payout, but the entered cash-quality and stress assumptions would not cover the regular dividend. The cushion deserves a closer look.
Educational scenario only. The cash-quality proxy subtracts the reader-entered PIK share from NII and then applies the entered NII change. PIK can ultimately be collected, and issuer definitions, fee income, spillover income, tax treatment, board decisions and portfolio changes can alter actual dividend capacity. This is not a forecast or investment, financial, tax, accounting or legal advice.
The first calculation asks whether reported NII covered the total payout. The second separates the regular dividend from a supplemental payout that may not represent the same recurring commitment. The third deliberately weakens the example by removing an entered share of Payment-in-Kind income and applying an entered NII change.
That stressed cash-quality figure is not a forecast. It is a way to expose the assumption hiding underneath a clean coverage ratio.
Regular versus supplemental dividends
A BDC can pay a regular dividend, a supplemental dividend, or both. Combining them is useful when asking whether the entire quarterly payout was covered. Separating them is useful when asking whether the recurring dividend has a larger cushion than the headline payout suggests.
Suppose a BDC reports $0.55 of NII per share, a $0.48 regular dividend and a $0.02 supplemental dividend. Total coverage is 1.10 times. Regular-dividend coverage is about 1.15 times.
Neither number guarantees the board's next decision. The distinction simply prevents a variable supplemental payment from being mistaken for the same obligation as the regular payout.
How higher rates move through NII
A higher benchmark does not flow straight into the dividend. It moves through an earnings bridge.
Asset income
Floating-rate loans can reprice upward when SOFR rises. That can increase interest income if borrowers continue paying.
Funding cost
The BDC must finance the portfolio. Floating-rate credit facilities can reprice too, while new fixed-rate unsecured debt may carry a higher coupon.
Credit and cash quality
The borrower absorbs the higher loan rate. If cash flow weakens, the BDC may receive more payment-in-kind income, amend the loan or eventually place it on non-accrual.
What remains
NII is what remains after investment income, funding expense, management fees and operating costs move through the period.
This is why the sequence matters:
floating-rate asset income -> funding and operating costs -> NII -> distribution coverage

The September 2026 test
The Federal Reserve raised its target range to 3.75% to 4.00% on September 16, 2026, and the Secured Overnight Financing Rate (SOFR) was 3.88% on September 24. Those rates can support income on floating-rate assets, but they also raise the cost carried by borrowers and some BDC liabilities.
ARCC's September financing shows the matching problem clearly. Ares Capital issued $750 million of 6.250% unsecured notes and swapped the full amount to three-month SOFR plus 1.85250%. The liability now floats more like much of the asset book.
That does not tell investors whether ARCC's dividend is safe by itself. It shows why coverage must be analyzed as a spread between asset income and total costs, then checked against credit performance.

What does NII mean?
NII stands for net investment income. For a BDC, it is generally the investment income left after interest expense, management fees, operating expenses, and other costs.
Most BDC income comes from loans to private companies. The BDC collects interest and fees, pays its own funding and operating costs, and reports what remains as NII.
If the dividend is the cash leaving the machine, NII shows how much current-period income the machine produced.
What is a good NII coverage ratio?
There is no universal cutoff, but investors usually prefer coverage meaningfully above 1.00x.
- 1.00x means the payout was just covered.
- 1.10x means the BDC earned a 10% cushion over distributions.
- 1.20x means the reported cushion was 20%.
Higher is generally better only when the income is durable.
A 1.20x ratio built on unusually high fee income or growing PIK may be less reassuring than a 1.10x ratio built on recurring cash interest. Coverage measures arithmetic. Durability requires underwriting.
Why coverage matters
Coverage is a pressure gauge for the dividend.
When NII consistently exceeds distributions, the BDC has more room to absorb:
- lower asset yields;
- rising funding costs;
- slower originations;
- weaker fee income;
- borrower stress;
- non-accruals.
When coverage is thin, small changes in the portfolio can move the payout from earned to under-covered.
That is why a large dividend yield should never be read without the coverage ratio underneath it.
What can make NII coverage look stronger than it is?
PIK income
Payment-in-kind income can increase reported NII before cash is collected. PIK is not automatically bad, but rising PIK may indicate that borrowers need relief.
Temporary fee income
Origination, amendment, prepayment, and structuring fees can lift one quarter. They may not repeat.
High base rates
Many BDC assets are floating rate. Higher rates can increase lender income, but they also increase borrower interest expense.
The lender may earn more at the same time the borrower becomes less able to pay.
Fee waivers or expense support
Temporary waivers can improve NII. Investors should understand whether reported coverage would remain intact without them.
The dividend-quality dashboard
NII coverage should be read with four companion signals.
| Signal | Why it matters |
|---|---|
| Cash quality | Dividends are paid in cash, so non-cash income deserves scrutiny |
| NAV per share | Falling NAV can reveal weakening asset value before coverage breaks |
| Non-accruals | Loans that stop paying can pressure future NII |
| Funding cost | Higher liability costs can compress the spread supporting the dividend |
A BDC can pass the coverage test and still fail the broader pattern.

NII coverage versus NAV
Coverage measures income support.
NAV measures reported portfolio value after liabilities.
A BDC with strong coverage and falling NAV deserves a closer look. The income statement may still look healthy while portfolio marks weaken.
A strong pattern is:
- coverage above 1.00x;
- stable or rising NAV;
- contained non-accruals;
- modest PIK;
- manageable leverage and funding costs.
A weaker pattern is:
- thin coverage;
- falling NAV;
- rising PIK;
- growing non-accruals;
- higher funding costs.
The pattern matters more than any isolated ratio.
NII coverage and non-accruals
Non-accruals are loans that are no longer producing normal interest income because collection has become uncertain.
If non-accruals rise, future NII may weaken. If NII weakens, dividend coverage may tighten. If coverage tightens while NAV also falls, the market may question the payout before management changes it.
This is how BDC risk often travels:
borrower stress → lower cash collection → weaker NII → thinner coverage → dividend pressure
How investors should use the ratio
Use NII coverage as a first test, not a final verdict.
In the next quarter, repeat the same calculation and compare the result with cash collections, NAV, non-accruals, PIK income, and funding costs. A trend is more informative than one isolated ratio.
Ask:
- Is coverage above or below 1.00x?
- Has it improved or weakened over several quarters?
- How much NII is recurring cash income?
- Is fee income unusually high?
- Is PIK rising?
- Are non-accruals increasing?
- Is NAV stable?
- Are funding costs rising faster than asset yields?
The goal is not to worship one ratio.
The goal is to understand the dividend machine.
Learn the formula, then inspect the income
The Drift Academy lets you practice how borrower payments, funding costs and credit losses become net investment income. The BDC Credit & Income Monitor applies selected coverage measures across ten BDCs and labels issuer-specific definitions so unlike figures are not mistaken for identical ones. The BDC Stress Map shows why a covered dividend can still deserve scrutiny when NAV, non-accruals or PIK move the wrong way.
Investor quick answers
What is the NII coverage ratio?
It is NII per share divided by distributions per share. It shows whether current-period net investment income covered the payout.
Is 1.00x coverage good?
It means the payout was covered, but there was no reported cushion.
Is 1.10x coverage strong?
It is usually healthier than 1.00x because the BDC earned 10% more NII than it distributed. Investors should still test income quality and credit trends.
Can a BDC cover its dividend and still be risky?
Yes. Coverage can remain above 1.00x while NAV falls, PIK rises, non-accruals increase, or funding costs pressure future earnings.
Why does PIK matter?
PIK can increase reported income before cash is collected, making coverage look stronger than cash support really is.
Should supplemental dividends be included in NII coverage?
Include them when testing whether the total payout was covered. Also calculate regular-dividend coverage separately so a variable supplemental payment does not obscure the recurring hurdle.
Does coverage above 1.00x guarantee the dividend?
No. Coverage is period-specific accounting evidence. The board controls the dividend, and future NII can change with rates, repayments, fee income, funding costs and credit performance.
