A mark isn't a fact: what BDC loan marks reveal when they disagree

The same syndicated loan often sits on a dozen BDC balance sheets. If value were a fact, every lender would mark it at the same price. They don't, and how the marks converge carries information.

In my last post I asked whether the calm in private credit is real, or just an artifact of how these loans get valued. The question stuck with me, so I went looking for a way to test it.

The test

A single syndicated loan often sits on a dozen BDCs' books at once: same borrower, same seniority, same maturity. Each BDC reports a fair value for it every quarter in public filings.

If a loan's value were a fact, every lender would mark it at the same price.

They don't.

An example: PetVet Care Centers

Through 2025, most lenders carried PetVet in the high 90s. Ares marked it lower, quarter after quarter.

Then the pack started to move. A year on, the consensus has fallen about seven points, toward where Ares had been sitting all along.

Dispersion versus convergence

Some dispersion is expected and innocent:

Entry price. A lender who bought at a discount may anchor differently from one who funded at par.
Models and inputs. Comparable-yield approaches, discount-rate choices and third-party valuation agents differ.
Position size and role. An agent or large holder may have better information, or different incentives.

But there is information in convergence. When one lender's mark leads and the rest drift toward it over the following quarters, the early mark was saying something the others weren't yet willing to say. Across a large panel of shared loans, you can measure:

Which managers tend to lead and which tend to lag
Whether marks systematically drift down (late recognition) rather than randomly around a mean
How far, on average, consensus marks sit from where the loan eventually settles

This is a better test of "is the calm real?" than looking at any one fund's aggregate NAV.

The consumer credit contrast

A mark isn't a fact, it's an opinion. That is where consumer credit people have it a bit easier: a missed payment is a missed payment. Delinquency rolls and charge-offs are observed, not estimated. Private credit runs on quarterly estimates of value that rarely trade.

That doesn't make private credit marks wrong. It means investors, LPs and lenders to these vehicles should treat marks as a distribution of opinions and pay attention to who is moving first.
