To estimate the FFO/Net debt ratio for 2022 we first compute the net debt position.  
Net debt is defined as total interest‑bearing liabilities minus cash and short‑term financial assets:

- Other non‑current financial liabilities (2023‑01‑01): 71,058 M €  
- Other current financial liabilities (2023‑01‑01): 71,844 M €  

Total financial liabilities = 142,902 M €  

Cash and cash equivalents (2023‑01‑01): 10,948 M €  
Other current financial assets (2023‑01‑01): 58,033 M €  

Cash + short‑term assets = 68,981 M €  

Net debt = 142,902 M € – 68,981 M € = 73,921 M €  

Next, funds from operations (FFO) are approximated by adding back non‑cash charges to the net loss:

- Net profit (loss) 2022: ‑18,225 M €  
- Depreciation & amortisation: +11,079 M €  
- Impairment loss reversal: +1,762 M €  
- Net change in fair value (loss): +849 M €  
- Other income/expense excluded from EBE (non‑cash): ‑687 M €  
- Loss on disposal of non‑current assets: +143 M €  
- Share of profit of associates (non‑cash): ‑759 M €  
- Dividends received (cash): +590 M €  

Summing these gives FFO ≈ ‑5,248 M €.

Finally, the ratio is:

FFO / Net debt = ‑5,248 M € / 73,921 M € ≈ ‑0.071.

Rounded to two decimal places this is –0.07.
