I need to estimate the FFO / Net Debt ratio for 2022.

**Step 1: Calculate FFO (Funds From Operations)**

FFO is typically calculated as net income plus depreciation & amortization plus other non-cash charges, adjusted for working capital changes. A common approximation:

FFO ≈ Net Income + Depreciation + Amortization + Impairment losses + Provisions adjustments - Gains on disposal of assets

For the period 2022-01-01 to 2023-01-01 (fiscal year 2022):
- Profit Loss: 448,000,000 EUR
- Depreciation Expense: 491,000,000 EUR
- Amortisation Expense: 233,000,000 EUR
- Adjustments for Impairment Loss: 10,000,000 EUR
- Adjustments for Provisions: 92,000,000 EUR
- Adjustments for Losses/Gains on Disposal of Noncurrent Assets: -191,000,000 EUR (gain)
- Adjustments for Undistributed Profits of Associates: -2,000,000 EUR

FFO ≈ 448 + 491 + 233 + 10 + 92 - 191 - 2 = 1,081 million EUR

Alternatively, a simpler approach: FFO = EBITDA - Net interest paid - Taxes paid
- EBITDA: 1,505,000,000 EUR
- Interest Paid: 75,000,000 EUR
- Income Taxes Paid: 201,000,000 EUR

FFO = 1,505 - 75 - 201 = 1,229 million EUR

Let me use the first approach which is more standard for credit analysis: FFO ≈ 1,081 million EUR.

**Step 2: Calculate Net Debt**

Net Debt = Total Financial Liabilities - Cash and Cash Equivalents

At 2023-01-01 (end of fiscal year 2022):
- Other Noncurrent Financial Liabilities: 5,867,000,000 EUR
- Other Current Financial Liabilities: 1,022,000,000 EUR
- Total Financial Liabilities: 5,867 + 1,022 = 6,889,000,000 EUR
- Cash and Cash Equivalents: 2,584,000,000 EUR
- Other Current Financial Assets: 14,000,000 EUR
- Other Noncurrent Financial Assets: 70,000,000 EUR

Net Debt = 6,889 - 2,584 - 14 - 70 = 4,221 million EUR

Or simply: Net Debt = 6,889 - 2,584 = 4,305 million EUR (without netting financial assets)

**Step 3: Calculate FFO / Net Debt**

Using FFO = 1,081 and Net Debt = 4,305:
FFO / Net Debt = 1,081 / 4,305 ≈ 0.251

Using the EBITDA-based FFO = 1,229 and Net Debt = 4,305:
FFO / Net Debt = 1,229 / 4,305 ≈ 0.2855

Let me use the more standard credit-analysis FFO approach (cash flow based):
FFO = Net Income + D&A + non-cash items = 448 + 491 + 233 + 10 + 92 - 191 - 2 = 1,081

FFO / Net Debt = 1,081 / 4,305 ≈ 0.251

Rounding, approximately 0.25.
