To estimate the FFO / Net Debt ratio for 2022, we need to calculate the Funds From Operations (FFO) and Net Debt for the period ending 2022-12-31 (which corresponds to the 2023-01-01 date in the balance sheet facts).

**1. Calculate FFO for 2022:**
FFO is typically calculated as Profit/Loss plus Depreciation & Amortization, plus/minus Impairment losses/reversals, and adjusted for net finance costs.
- Profit Loss (2022): 1,948,767,000 EUR
- Depreciation And Amortisation Expense (2022): 462,694,000 EUR
- Impairment Loss (2022): 197,761,000 EUR
- Reversal Of Impairment Loss (2022): -125,973,000 EUR (subtracting reversals to find the gross impairment)
- Finance Income Cost (2022): -94,077,000 EUR (adding back net interest to get an operating metric before financing)

FFO = 1,948,767,000 + 462,694,000 + 197,761,000 - 125,973,000 + 94,077,000 = 2,577,326,000 EUR

**2. Calculate Net Debt for 2022 (end of year):**
Net Debt = Total Financial Liabilities - Cash and Cash Equivalents - Current Derivative Financial Assets - Noncurrent Derivative Financial Assets (since derivatives act as hedging/financial instruments for an energy company).
- Noncurrent Financial Liabilities (2023-01-01): 2,844,559,000 EUR
- Current Financial Liabilities (2023-01-01): 1,109,297,000 EUR
- Cash And Cash Equivalents (2023-01-01): 409,252,000 EUR
- Current Derivative Financial Assets (2023-01-01): 1,833,683,000 EUR
- Noncurrent Derivative Financial Assets (2023-01-01): 437,341,000 EUR

Net Debt = (2,844,559,000 + 1,109,297,000) - 409,252,000 - 1,833,683,000 - 437,341,000 = 1,273,580,000 EUR

**3. Calculate the Ratio:**
FFO / Net Debt = 2,577,326,000 / 1,273,580,000 ≈ 2.0244
