Comparison
| Aspect | Pro Rata tranche | Institutional tranche |
|---|---|---|
| Example tranche | RCF, TLA | TLB, Second Lien |
| Lender | Commercial Banks | CLOs, Loan Funds, Direct Lenders |
| Voting Allocation | equal per lender | weighted by holding |
| Amortization | Amortizing | Bullet or minimal Amortizing |
| Coupon | lower | higher |
| Secondary market | limited | active |
| Covenant type | Maintenance | Incurrence (Cov-Lite) |
Consequence
"Pro Rata" gets its name because repayments and drawdowns are distributed equally across all pro-rata lenders. Institutional tranches have their own allocation mechanics.
Common pitfalls
- Modeling: pro-rata vs institutional amortization mechanics differ — pro rata is repaid in parallel, institutional sequentially
- Lender voting in restructurings differs — an important question in distress
Pitch tip
Question: "Pro rata or institutional?"
Answer: "Pro rata when the banking relationship matters (common in the middle market). Institutional when the volume is larger and speed-to-close is critical (US style). A mix is usual: TLA pro rata + TLB institutional"
