A PIK toggle roughly doubles the odds the loan goes delinquent

Private Credit Brief · Issue #2

Most candidates describe a PIK toggle as flexibility. Supervisors measure it as a warning.

The number

The Financial Stability Board studied loans held by US business development companies and found that the use of PIK toggles is associated with a 1 to 2 percentage point increase in the likelihood of a loan becoming delinquent in the following quarter.

The unconditional probability is 3%.

So a toggle roughly doubles the near term odds. That is a base rate, not a rounding error.

For scale, PIK is used in approximately 12% of private credit loans, with toggles accounting for about half of those cases. The use of both PIK notes and PIK toggles has risen significantly since 2022, coinciding with the period of rising interest rates.

The exception that matters

Here is the part almost nobody quotes.

The FSB finds the correlation between PIK use and borrower stress holds unless the company has a private equity sponsor, which it attributes to sponsors being able to inject liquidity during periods of financial stress.

So the question in an interview is not "is there PIK on this deal?"

It is: who is behind this borrower, and did they put money in alongside the amendment?

Answer the first and you sound like you read the term sheet. Answer the second and you sound like you underwrote it.

Why the growing claim hurts

PIK compounds. A $100mm loan at a 10% PIK coupon is $110mm after one year and $121mm after two. No cash leaves the borrower, and the lender books income it has not collected on a claim that grows every quarter.

That matters more in private credit than elsewhere. Federal Reserve staff put the post-default value of a direct loan at around 33 percent, against 52 percent for syndicated loans and 39 percent for high yield.

A claim that has been accreting for three years is recovered at about a third of face.

What separates a good answer from a mechanical one

Weak. "PIK is interest added to principal instead of paid in cash." Correct, and it shows no judgment.

Better. Separate origination PIK from amendment PIK. One is a structure. The other is a workout.

Strong. Name the base rate, name the sponsor test, then say what you would condition the amendment on.
