To estimate the FFO (Funds From Operations) to Net Debt ratio for VINCI at the end of 2022, we typically use the standard corporate finance definitions for these metrics.

1. **Funds From Operations (FFO):**
FFO is most commonly approximated as Net Income plus non-cash expenses (primarily Depreciation and Amortization). 
- Net Income ("Profit Loss") = 4,417,000,000 EUR
- D&A ("Adjustments For Depreciation And Amortisation Expense") = 3,613,000,000 EUR
FFO = 4,417,000,000 + 3,613,000,000 = 8,030,000,000 EUR

2. **Net Debt:**
Net Debt is generally calculated as Total Borrowings minus Cash and Cash Equivalents.
- Short-term Borrowings = 6,368,000,000 EUR
- Long-term Bonds ("Noncurrent Portion Of Noncurrent Bonds Issued") = 20,425,000,000 EUR
- Other Long-term Borrowings ("Noncurrent Portion Of Other Noncurrent Borrowings") = 3,205,000,000 EUR
Total Borrowings = 6,368,000,000 + 20,425,000,000 + 3,205,000,000 = 29,998,000,000 EUR

- Cash And Cash Equivalents = 12,578,000,000 EUR
Net Debt = 29,998,000,000 - 12,578,000,000 = 17,420,000,000 EUR

3. **FFO / Net Debt Ratio:**
Ratio = 8,030,000,000 / 17,420,000,000 ≈ 0.461
