To estimate the FFO/Net‑debt ratio for 2022 we approximate Funds From Operations (FFO) by the operating cash flow reported in the cash‑flow statement (458,926,000 EUR). Net debt is calculated as total financial liabilities (including lease liabilities) minus cash and cash equivalents:

- Total financial liabilities (2023‑01‑01): 1,751,255,000 + 150,955,000 + 76,644,000 + 389,716,000 + 6,362,000 = 2,374,932,000 EUR  
- Cash and cash equivalents (2023‑01‑01): 392,811,000 EUR  

Net debt = 2,374,932,000 – 392,811,000 = 1,982,121,000 EUR  

FFO / Net debt = 458,926,000 / 1,982,121,000 ≈ 0.2315, which we round to 0.23.
