I need to calculate the Net Debt / EBITDA ratio for 2022 using S&P methodology.

First, let me identify the relevant figures for 2022 (2022-01-01 to 2023-01-01):

**EBITDA for 2022**: 3,160,679,000 EUR

**Net Debt calculation (S&P methodology)**:
S&P methodology typically defines Net Debt as:
- Total Debt (short-term + long-term interest-bearing debt) minus
- Cash and Cash Equivalents minus
- Liquid investments (if any)

From the balance sheet at 2022-01-01 (start of 2022) and 2023-01-01 (end of 2022):

Let me find debt figures. Looking at the data:

**Financial Liabilities:**
- 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

Wait - I need to be more careful. For Net Debt at year-end 2022, I should use 2023-01-01 balance sheet figures (which represent end of 2022).

However, I also need to check if there are other items. Let me also look at 2022-01-01 figures for comparison, but for the 2022 ratio, we typically use end-of-period debt.

Actually, looking more carefully at S&P methodology: Net Debt is usually calculated as:
- Short-term debt + Long-term debt + Current portion of long-term debt - Cash and cash equivalents

From the data:
- Noncurrent Financial Liabilities 2023-01-01: 2,844,559,000 EUR
- Current Financial Liabilities 2023-01-01: 1,109,297,000 EUR

Total Debt = 2,844,559,000 + 1,109,297,000 = 3,953,856,000 EUR

Cash and Cash Equivalents 2023-01-01: 409,252,000 EUR

**Net Debt** = 3,953,856,000 - 409,252,000 = 3,544,604,000 EUR

Wait - I should also check if there are other items to consider. Let me check "Current Derivative Financial Liabilities" and "Noncurrent Derivative Financial Liabilities" - these are typically not part of debt in the traditional sense for Net Debt calculations, but rather operating/hedging items.

Also, I need to check if there are money market transactions or other liquid investments. The data shows:
- "Cash Inflow From Money Market Transactions" and "Cash Outflow From Money Market Transactions" - these are cash flow items, not balance sheet items.

Looking at "Investments And Other Receivables" - 2023-01-01: 945,454,000 EUR. Some of these might be liquid, but without more detail, I'll stick to standard definition.

Actually, let me reconsider. S&P methodology sometimes includes:
- Total debt (financial liabilities)
- Less: Cash and cash equivalents
- Less: Short-term liquid investments

From the balance sheet, I don't see a separate line for short-term liquid investments. "Current Derivative Financial Assets" 2023-01-01: 1,833,683,000 EUR - these are derivatives, not typically counted as cash-like.

Let me also check if there are lease liabilities included in financial liabilities. The data shows "Payments Of Lease Liabilities Classified As Financing Activities" - this suggests leases are part of financing activities.

Actually, I need to be more careful. Looking at the cash flow statement, "Payments Of Lease Liabilities Classified As Financing Activities" 2022-01-01 - 2023-01-01: 11,447,000 EUR. This is a financing outflow, suggesting lease liabilities are in financial liabilities.

For S&P methodology, we typically want:
- Gross debt: All interest-bearing liabilities (including bank loans, bonds, finance leases)
- Less: Cash and cash equivalents
- Less: Marketable securities/liquid investments

Let me check if there are other potential debt items. Looking at "Noncurrent Payables" and "Trade And Other Current Payables" - these are typically trade payables, not debt.

Also, I should check "Current Derivative Financial Liabilities" 2023-01-01: 1,491,588,000 EUR and "Noncurrent Derivative Financial Liabilities" 2023-01-01: 1,069,177,000 EUR. These are derivative liabilities, not typically included in "debt" for Net Debt purposes unless they are net-settled and in-the-money against the company. Usually, for credit analysis, derivative liabilities might be included if they represent actual obligations.

However, standard S&P Net Debt typically focuses on:
- Bank debt
- Bonds
- Finance leases
- Less: Cash

Let me recalculate with a more conservative approach including all financial liabilities:

**Gross Debt** = Noncurrent Financial Liabilities + Current Financial Liabilities
= 2,844,559,000 + 1,109,297,000 
= 3,953,856,000 EUR

**Cash and Cash Equivalents** = 409,252,000 EUR

**Net Debt** = 3,953,856,000 - 409,252,000 = 3,544,604,000 EUR

**EBITDA** = 3,160,679,000 EUR

**Net Debt / EBITDA** = 3,544,604,000 / 3,160,679,000 = 1.121

Wait - I need to double check. Let me also verify if I should use average or year-end debt. S&P typically uses year-end debt for this ratio, though some variations use average. For consistency with typical reporting, I'll use year-end (2023-01-01) figures.

Actually, let me reconsider whether to include derivative liabilities. In many credit analyses, derivative liabilities that are not collateralized or are part of normal hedging operations might be excluded. However, for a conservative S&P approach, one might include them if they represent actual economic obligations.

Let me check if there's any guidance in the data. The "Valuation And Realisationof Energyderivatives" in the income statement is -857,961,000 EUR for 2022, suggesting significant derivative activity.

For a cleaner S&P Net Debt, let me stick with financial liabilities only:
- Noncurrent Financial Liabilities: 2,844,559,000
- Current Financial Liabilities: 1,109,297,000
Total: 3,953,856,000

Less: Cash and Cash Equivalents: 409,252,000

Net Debt = 3,544,604,000

Net Debt / EBITDA = 3,544,604,000 / 3,160,679,000 = 1.1214...

Let me also consider if I should include the 2022-01-01 (beginning of year) or 2023-01-01 (end of year) balance. For a 2022 ratio, typically we use end-of-2022 figures, which are 2023-01-01 in this data structure.

Actually, I want to double-check my understanding of the dates. The period "2022-01-01 - 2023-01-01" represents the year 2022. The balance at "2023-01-01" represents the end of 2022.

Let me verify: EBITDA 2022-01-01 - 2023-01-01 = 3,160,679,000. This is the 2022 EBITDA.

For Net Debt at end of 2022, I use 2023-01-01 balance sheet figures.

Calculation:
Net Debt = (2,844,559,000 + 1,109,297,000) - 409,252,000 = 3,544,604,000

Ratio = 3,544,604,000 / 3,160,679,000 = 1.1214

Rounding to 2 decimal places: 1.12

Actually, let me think once more if there are other cash-like items. "Current Derivative Financial Assets" 2023-01-01: 1,833,683,000 EUR - these are derivative assets, not cash. "Investments And Other Receivables" 2023-01-01: 945,454,000 EUR - these include investments, which might have some liquid components, but without knowing the breakdown, I shouldn't assume they're cash-like.

I'll stick with the standard definition.
