Before you start
Read a BDC filing in order: four statements and the investment schedule, PIK income: distinguish the contract, the accounting and the cash
- Separate cost exposure from fair-value exposure.
- Explain numerator and denominator effects in a non-accrual percentage.
- Track positions entering, leaving and remaining on non-accrual.
Non-accrual is an income-recognition status
A non-accrual designation concerns recognition of investment income under the issuer's accounting policy. It is not a universal legal declaration that a borrower is bankrupt, that the investment is worth zero or that a specific recovery rate is certain. Policies can consider overdue payments, doubt about collection and other factors. Read the actual thresholds and exceptions rather than applying a generic number of days to every BDC. An investment can retain a positive fair value while income is no longer accrued, and a performing designation does not itself establish that a borrower is free of risk.
A common mistake
Treating a falling non-accrual fair-value percentage as proof that credit performance improved.
What to check in the disclosures
- Match cost with cost and fair value with fair value.
- Record all-investment versus debt-only scope.
- Trace individual entries, exits and mark movements.
- Read policies for income reversals and capitalized PIK.
Cost and fair value answer different exposure questions
The non-accrual amount at cost compares an investment basis with the matching portfolio cost. The fair-value measure compares the marked value with the matching portfolio fair value. A heavily written-down asset contributes less to the fair-value numerator, so a low fair-value percentage can coexist with a larger original exposure. Check whether the population is all investments, only debt investments or some other subset. A cost numerator divided by a fair-value denominator is a different, usually unintended ratio. The date, portfolio perimeter and treatment of accrued income must also match.
A changing percentage needs a position-level explanation
Between two periods, a ratio can change because a borrower resumed payments, a position was sold, an investment was restructured, its mark moved or the rest of the portfolio grew. These mechanisms have different implications. Selling a deeply impaired position can reduce reported non-accrual exposure while crystallizing a loss. Adding new performing investments can dilute the percentage without resolving old problems. Build an opening-to-closing list of entrants, exits and valuation changes, and investigate undisclosed movements rather than assigning a cause from the percentage alone. A missing schedule is a limitation to record, not proof of concealment.
Connect income reversals, carrying values and realizations
When accrual stops, uncollected amounts and capitalized balances may have different accounting treatment. Later sale proceeds need to be compared with both original or amortized cost and the value already marked in prior periods. Otherwise the analyst can count an old loss again. Keep a row for recognized income changes and a separate row for fair-value changes, then reconcile the net-asset result. The goal is not to label every accounting change as good or bad; it is to establish what changed economically, what was already recognized and what evidence would support a different assessment.
Synthetic: a lower fair-value share need not mean a recovery
A fictional portfolio has cost of 1,000 and fair value of 950. Non-accrual investments have cost 50 and fair value 20. The matching ratios are 50/1,000 = 5% at cost and 20/950 = 2.1053% at fair value. Suppose those same investments are marked down another 10 and nothing else changes. Total fair value becomes 940 and non-accrual fair value becomes 10, so the fair-value share falls to 1.0638%. Cost exposure remains 5%. The lower percentage came from deterioration in marks, not a demonstrated restoration of borrower payments.
Test your reasoning
A non-accrual asset's cost is 50 and fair value is explicitly zero. Should the asset disappear from the analysis?
Reveal the worked answer
No. Keep its cost exposure and the reported zero fair value. Zero is a measured input; it is not the same as an unknown value or evidence that the historical exposure never existed.
