NII Coverage Ratio: Is a BDC Dividend Actually Covered?
NII coverage ratio shows whether a BDC dividend is earned, thinly supported, or dependent on income quality that may not last.
Last updated: August 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.
Worked example
Suppose a BDC reports:
- NII per share: $0.55
- distributions per share: $0.50
The calculation is:
$0.55 ÷ $0.50 = 1.10x
The BDC earned $1.10 of NII for every $1.00 it distributed.
That usually indicates a modest cushion. It does not prove the dividend is safe. Investors still need to test the quality of the income, NAV trend, non-accruals, PIK income, and funding costs.
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.
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.

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.
