Valuation and Marks in Private Credit Funds

A publicly traded bond has a market price every few minutes: whatever the last trade printed. A loan held by a private credit fund usually has none of that — it may never trade again after origination, held by a small handful of lenders who intend to keep it to maturity. So how does the fund report a value for that loan each quarter? It marks it using a model, a broker quote if one can be found, or a valuation committee's judgment — a process with far more room for smoothing and delay than a market price allows.

Where the lag comes from

A public high-yield bond's price reacts to bad news — a weak earnings report, a sector downturn — within hours, because sellers who want out can find a price immediately, even a bad one. A private loan's next observable data point might be the borrower's quarterly financials, reviewed by the fund's valuation team weeks after quarter-end, filtered through a model that often anchors partly to the previous quarter's mark to avoid excessive volatility in reported fund performance. The result is a valuation series that looks smoother and less volatile than the fund's real economic risk — a known and studied feature of private credit and private equity marks generally.

Worked example

A private credit fund holds a $50 million loan to a mid-market company, marked at par (100) at the start of the quarter. Mid-quarter, the borrower loses its largest customer, cutting expected EBITDA by 30%. A comparable public high-yield bond from a similarly affected sector would likely reprice within days to reflect materially higher default risk, say down to 85.

1. At quarter-end, the fund's valuation team runs its DCF model, but the borrower's revised financials showing the customer loss aren't available until three weeks after quarter close.
2. The fund's reported mark for that quarter comes in at 96 — a partial adjustment based on qualitative flags (a covenant waiver request) rather than the full financial impact, since the hard numbers aren't in yet.
3. Next quarter, once full financials are available, the mark drops to 78, catching up to something close to where a liquid market would have already priced the loan a full quarter earlier. An investor who redeemed from the fund between those two quarter-ends would have received a NAV that was, in hindsight, meaningfully stale.

What this means in practice

This lag is precisely why private credit fund NAVs tend to show smoother, higher risk-adjusted returns than public credit indices over the same period — not because the underlying loans are actually safer, but because the marks update less often and less sharply. It also explains why private credit fund shares trading on secondary markets often change hands at a discount to reported NAV during stress periods: buyers price in the expectation that the official mark hasn't caught up yet.
