Key point
Par minus fair value = unrealized loss. A loan marked at 85% of par signals the manager already expects partial loss.
Compare
| Loan type | Position in capital stack | Typical recovery | Risk |
|---|---|---|---|
| First lien senior secured | Top -- gets paid first | 70-90% | Lowest |
| Unitranche | Single first-lien tranche blending senior + sub economics into one instrument at a single blended rate (SOFR+475 to SOFR+700 typical in middle market). Two-lender variants split economics via an Agreement Among Lenders (AAL) behind the scenes, but the borrower sees ONE loan with first-lien priority. | 75-85% (first-lien recovery profile, per Moody's middle-market LGD studies) | Moderate |
| Second lien | Behind first lien | 30-50% | Higher |
| Subordinated / mezz | Below all secured debt | 10-30% | High |
| Equity / warrants | Last in line, upside if exit | 0% or 100%+ | Highest |
Key point
Unitranche, clarified. A unitranche is NOT a 'blended first-and-second lien' instrument with mid-tier recovery. It is a single senior secured loan that combines what would otherwise be a separate first-lien and subordinated piece into one instrument with one blended interest rate. The borrower signs ONE credit agreement, the lender (or syndicate) has first-lien priority on collateral, and recovery in distress looks like senior-secured (~75-85%), not mezz. When two or more lenders share a unitranche, they may sign an Agreement Among Lenders (AAL) that re-tranches the economics privately — the 'first-out' lender gets paid first from collateral proceeds, the 'last-out' lender takes a higher coupon but absorbs the first dollars of loss. The borrower never sees the AAL; from their side it is still one loan with one rate. This single-instrument design is why unitranche grew so rapidly in middle-market private credit: faster execution, one set of covenants, one lender to negotiate with.

A BDC reports a loan at par $10M and fair value $7M. What is the most likely interpretation?
BDC yield spread vs Treasuries
Pick a publicly-traded BDC (ARCC, BXSL, OBDC, MAIN, etc.). Compute the spread between the BDC's dividend yield and the 10-year Treasury yield. Paper-buy with a thesis explaining whether the spread compensates for the credit risk you're taking.
