Error Handling
| Error | Cause | Solution |
|---|---|---|
| #DIV/0! in terminal value | WACC equals terminal growth | Terminal growth must be less than WACC |
| Negative FCF | High CapEx or WC needs | Review assumptions, may need different model |
| Unrealistic EV | Extreme growth assumptions | Benchmark against industry comparables |
