# Financial Calculations (Phase 3)

All calculation logic is consolidated into a single script that enforces the correct dependency chain internally.

1. Execute the script: `python skills/financial_calculations/scripts/calculate.py {markdown_file}`
2. Verify no errors were thrown.

## Changelog

- 2026-05-07: Updated `calculate.py` to correctly identify `interest_expense_net` and use absolute values for interest expense in the summary table, fixing WACC calculation issues.
