In middle-market leveraged buyouts and corporate recapitalizations, unitranche loans simplify borrower debt execution. Behind the scenes, Agreement Among Lenders (AAL) documents govern sophisticated First-Out Last-Out (FOLO) waterfall priorities that bifurcate pricing, amortization, and liquidation proceeds.
First-Out vs Last-Out Tranche Economics
How institutional credit funds structure synthetic senior and subordinated claims under a single credit agreement:
Following an acceleration event or material payment default, the AAL automatically flips from a pro-rata interest distribution waterfall to a sequential waterfall where 100% of principal recoveries pay down the First-Out tranche before the Last-Out tranche receives a single dollar.
Tranche Structural Risk Profiles Compared
| Debt Tranche | Leverage Attachment | Pricing Spread (SOFR +) | Enforcement Control |
|---|---|---|---|
| First-Out Senior Tranche | 0.0x – 2.5x EBITDA | + 275 – 350 bps | Immediate Post-Standstill |
| Last-Out Junior Tranche | 2.5x – 5.5x EBITDA | + 650 – 850 bps | Standstill Period (90–180d) |
| Blended Unitranche (Borrower Rate) | 0.0x – 5.5x EBITDA | + 525 – 600 bps | Administrative Agent Dispatched |
Key Intercreditor & AAL Covenants
Essential clauses negotiated between First-Out bank syndicates and Last-Out private credit lenders:
- Buyout Option (Par Value): Last-Out lenders retain an unconditional right to purchase First-Out loans at 100% par plus accrued interest to assume total control of workout proceedings.
- Enforcement Standstill Provisions: Restricts Last-Out lenders from initiating foreclosure actions for a negotiated 90 to 180-day window following financial covenant default.
- Excess Cash Flow (ECF) Sweep Allocations: Mandates that 100% of quarterly ECF sweeps amortize the First-Out balance until senior leverage drops below contracted thresholds.
