To estimate **FFO / Net debt** for 2022:

1. **Funds from operations (FFO)** can be approximated from cash-flow-related operating earnings before working capital movements. Using the provided cash flow facts:
   - Profit loss before tax: 756
   - Income tax expense adjustment: 344
   - Net financial interests: 90
   - Gain on disposal of noncurrent assets: -191
   - Depreciation expense: 491
   - Amortisation expense: 233
   - Impairment adjustments: 10
   - Provisions adjustments: 92
   - Undistributed profits of associates: -2
   - Interest paid: -75
   - Taxes paid: -201
   - Dividends received / paid classified as operating activities: -302

   Approximate FFO:
   \[
   756 + 344 + 90 - 191 + 491 + 233 + 10 + 92 - 2 - 75 - 201 - 302 = 1{,}245
   \]
   So, estimated **FFO = EUR 1,245 million**.

2. **Net debt** can be approximated as financial liabilities less cash and financial assets:
   - Other noncurrent financial liabilities: 5,867
   - Other current financial liabilities: 1,022
   - Cash and cash equivalents: 2,584
   - Other noncurrent financial assets: 70
   - Other current financial assets: 14

   \[
   \text{Net debt} = 5{,}867 + 1{,}022 - 2{,}584 - 70 - 14 = 4{,}221
   \]
   So, estimated **net debt = EUR 4,221 million**.

3. Therefore:
   \[
   \frac{FFO}{Net debt} = \frac{1{,}245}{4{,}221} \approx 0.295
   \]
