In middle-market leveraged buyouts and corporate recapitalizations, unitranche facilities combine senior and junior risk profiles into a single legal instrument. First-Out Last-Out (FOLO) Waterfall Structuring governed by Agreements Among Lenders (AAL) establishes strict payment prioritization, yield bifurcations, and voting control under financial distress.
First-Out vs Last-Out Cash Flow Distribution
How the payment waterfall prioritizes interest coupons and principal recoveries:
The borrower executes a single promissory note with a blended interest rate. Behind the scenes, the AAL allocates cash collections: First-Out (FO) participants receive lower-yield SOFR + 350 bps with first priority on liquidation proceeds, while Last-Out (LO) institutional funds capture SOFR + 850 bps subordinated to FO interest and principal amortizations.
Unitranche Tranche Profiles Compared
| Debt Tranche | Leverage Attachment | Typical Coupon Spread | Recovery Expectation |
|---|---|---|---|
| First-Out Senior Unitranche (FO) | 0.0x - 2.5x EBITDA | SOFR + 325 - 375 bps | 95% - 100% Par Recovery |
| Last-Out Junior Unitranche (LO) | 2.5x - 5.5x EBITDA | SOFR + 750 - 900 bps | 60% - 80% (Subordinated) |
| Mezzanine / Preferred Equity | 5.5x - 7.0x EBITDA | 13.0% - 16.0% Fixed / PIK | First-Loss Equity Cushion |
Private Debt Covenant Structuring Invariants
Essential clauses required when drafting institutional unitranche credit agreements:
- Trigger Event Waterfall Flipping: Enforce automatic conversion to strict sequential FO principal amortization upon financial covenant breach or bankruptcy filing.
- Voting Rights & Buyout Option: Grant Last-Out lenders a 30-day window to purchase FO claims at par plus accrued interest before foreclosure remedies occur.
- Restricted Payments & Cash Sweeps: Mandate 100% excess cash flow sweeps directly toward First-Out debt reduction when Net Debt / EBITDA exceeds 4.0x.
