In complex middle-market corporate and real estate leveraged recapitalizations, unitranche loan structures combine senior and junior risk under a single credit agreement. Private Debt Waterfall Mechanics and FOLO (First-Out Last-Out) Tranches govern payment priorities, loss absorption, and buyout rights under an Agreement Among Lenders (AAL).
The Multi-Tier Cash Distribution Waterfall
How operating cash flows and liquidation proceeds cascade through the capital stack:
While the borrower sees a single blended interest rate, the AAL splits principal and coupon distribution internally. The First-Out (FO) lender holds super-senior payment priority and lower pricing (SOFR + 350 bps), while the Last-Out (LO) lender absorbs initial defaults and earns higher subordinated yields (SOFR + 850 bps).
Unitranche Debt Tranche Architecture Compared
| Tranche Position | Loss Absorption Order | Target Margin (Spread) | Voting Governance |
|---|---|---|---|
| First-Out (FO) Revolver / Term Loan | Protected (Senior Lien Priority) | SOFR + 325 - 400 bps | Primary Control over Enforcement |
| Last-Out (LO) Junior Term Loan | First Loss (Subordinated) | SOFR + 800 - 1,000 bps | Consent Required on Material Terms |
| Preferred Equity / HoldCo PIK | Junior to all Debt Obligations | 14.0 - 18.0% Fixed IRR (PIK) | Board Observer / Information Rights |
Underwriting & Intercreditor Covenants
Essential structuring terms required to protect capital recovery across credit cycles:
- Standstill & Enforcement Periods: Establish clear 90-120 day standstill windows restricting LO unilateral foreclosure actions upon covenant breach.
- LO Par Buyout Rights: Grant the Last-Out lender the legal right to purchase First-Out debt at par plus accrued interest to assume complete workout control.
- Dynamic Cash Sweep Traps: Trigger mandatory 100% excess cash flow debt paydowns directly to the First-Out tranche if the leverage ratio exceeds target thresholds.
