Middle-market direct lending transactions increasingly rely on unitranche debt structures to streamline execution. Underneath a unified credit agreement lies the Agreement Among Lenders (AAL), which establishes First-Out Last-Out (FOLO) waterfall mechanics, synthetic subordination, and customized risk-adjusted yield profiles.
FOLO Tranche Dynamics & Payment Blockage Periods
How private credit funds structure priority cash-flow distributions and default remedies:
Prior to an Event of Default (EoD), interest payments flow pro-rata to both First-Out (revolver/bank) and Last-Out (institutional fund) tranches. Upon default trigger, the waterfall shifts to strict sequential paydown, channeling 100% of principal recoveries and interest to the First-Out lender until full extinguishment.
Direct Lending Tranche Structures Compared
| Debt Facility Type | Target Leverage (Debt/EBITDA) | Typical Pricing Spread | Enforcement Control |
|---|---|---|---|
| First-Out Tranche (AAL Unitranche) | 1.0x - 2.5x EBITDA | SOFR + 275 - 350 bps | Immediate Blockage Rights |
| Last-Out Tranche (AAL Unitranche) | 2.5x - 5.5x EBITDA | SOFR + 650 - 800 bps | Standstill (90-180 Days) |
| Traditional Mezzanine Subordinated | 5.0x - 6.5x EBITDA | 12.0% - 15.0% Fixed/PIK | Subordinated Intercreditor |
Intercreditor Covenants & Structuring Best Practices
Institutional guidelines for managing complex capital structures in private credit portfolios:
- Standstill Period Calibration: Enforce 90- to 150-day enforcement standstill periods to allow orderly consensual workouts before collateral liquidation.
- Buyout Rights at Par: Protect Last-Out capital by embedding explicit rights to purchase First-Out loans at par plus accrued interest upon uncured default.
- Voting Rights Partitioning: Delineate 'Sacred Rights' (maturity extension, principal forgiveness) requiring 100% approval versus operational covenant waivers.
