Question

How do you model the cash sweep technically in Excel?

Answer

Standard formula with a MIN function for the bound logic:

```
Cash Sweep = MIN(
Excess Cash Available,
Outstanding Debt Balance,
Sweep % × Excess Cash
)
```

  • Excess Cash: $30m
  • Outstanding TLB: $80m
  • Sweep %: 75%
  • Sweep = MIN(30, 80, 22.5) = $22.5m

Three bounds at once:

  1. You can't sweep more than the available excess cash
  2. You can't sweep more than the outstanding debt
  3. You can't sweep more than the contractual sweep percentage allows
  • Forgetting that the sweep comes after mandatory repayments
  • Not trapping negative excess cash (MIN could go negative) — fix: MAX(0, ...)
  • Cascade across several tranches: senior first in full, then junior

In a modeling test bankers say 'Build me the cash sweep waterfall' — a structured answer: 'Excess cash → senior debt first in full, then mezzanine, then shareholder loan. Each tranche gets its own MIN bound.' Cleanly built with helper cells, not one mega-formula.
