BDC NAV and Non-Accruals: How Credit Trouble Appears
Credit trouble rarely arrives as one clean number. Learn to read marks, non-accruals and realized losses as a sequence.
Private Credit Foundations, Lesson 4. Estimated time: 14 minutes.
Bad loans seldom ring the bell before entering the building.
They appear as smaller clues: a lower fair-value mark, an amendment, more Payment-in-Kind (PIK) interest, a weaker internal risk grade, then perhaps non-accrual and a realized loss.
This lesson teaches you to read those clues across a Business Development Company (BDC) portfolio without treating any single figure as a verdict.
What you will learn
By the end of the lesson, you should be able to:
- explain Net Asset Value (NAV) and build a simple NAV bridge;
- distinguish cost from fair value;
- interpret non-accruals at cost and fair value;
- separate unrealized marks from realized outcomes; and
- identify credit deterioration that may precede non-accrual.
The sequence of credit trouble
Fair value can move before cash stops
BDCs report investments at fair value under their applicable accounting framework. A mark can decline because market yields changed, company performance weakened, comparable values fell or recovery expectations deteriorated.
The loan may still pay interest. A markdown therefore does not prove default. It does say the current estimate of value has changed and deserves attribution.
Non-accrual changes income recognition
When collection becomes sufficiently doubtful under an issuer's policy, a loan may be placed on non-accrual and contractual interest recognition generally stops. Policies vary, so compare issuers carefully and read the note.
Non-accrual at cost shows the investment basis associated with troubled assets. Non-accrual at fair value shows how those assets are currently marked. A large gap can indicate that substantial damage has already been recognized, though recovery remains uncertain.
Realization closes part of the argument
An unrealized loss is a current valuation change on an investment still held. A realized loss generally records an outcome through a sale, restructuring, repayment below basis or write-off.
Neither should be read lazily. An unrealized mark can reverse. It can also be the first honest sentence in a longer story.
Test your credit radar
Build the NAV bridge
A simplified per-share bridge begins with prior NAV, adds current earnings and realized or unrealized gains, subtracts dividends and realized or unrealized losses, then includes the effect of share issuance, repurchases and other changes.
The bridge asks a better question than “Did NAV fall?”
It asks why.
A decline caused by a temporary broad-market mark is different from repeated borrower-specific markdowns. A decline after a dividend exceeding earnings is different from one produced by issuing shares below NAV. The destination can match while the route tells a different story.
Look beyond reported non-accruals
A low non-accrual rate is welcome evidence, not a force field.
Watch for:
- loans marked materially below cost while still accruing;
- rising PIK income at weak borrowers;
- amendments that extend maturities or reduce cash coupons;
- increasing loans in weaker internal risk categories;
- repeated restructurings; and
- realized losses following earlier markdowns.
The goal is not to accuse every amended loan of failure. It is to notice when several clues point in the same direction.
Apply it to a filing
Take one BDC's latest investment schedule. Sort, if practical, by the largest gap between cost and fair value. Identify which loans are on non-accrual and which remain accruing.
Then reconcile the quarter's NAV change using earnings, distributions, realized results, unrealized marks and share activity. Write down any remainder you cannot explain. That remainder is a research task, not a rounding error to wave away.

Key Terms
Business Development Company (BDC): A closed-end company that elects BDC status under the Investment Company Act of 1940 and typically invests in private or smaller public businesses.
Net Asset Value (NAV): Assets minus liabilities, often expressed per share.
Payment-in-Kind (PIK): Interest added to a loan balance instead of paid in current cash.
Source Notes
The BDC structure and risk discussion follows the U.S. Securities and Exchange Commission's BDC investor bulletin. Fair values, risk grades, non-accruals and realized or unrealized changes must be sourced from the applicable issuer's filed financial statements and notes. Fair-value and non-accrual policies can differ by issuer; comparisons should preserve those definitions.
