To estimate the Net Debt / EBITDA ratio for 2022 using the S&P methodology, we need to derive the components based on the provided facts:

1.  **Net Debt**:
    *   **Financial Liabilities (Borrowings)**:
        *   Noncurrent portion of bonds: 22,212 million EUR (2022-01-01 position, effectively end of 2021)
        *   Noncurrent portion of other borrowings: 2,757 million EUR
        *   Short-term borrowings: 5,769 million EUR
        *   Total Gross Debt (approx.): 22,212 + 2,757 + 5,769 = 30,738 million EUR.
    *   **Cash and Cash Equivalents**: 11,065 million EUR.
    *   **Current Cash Management Financial Assets**: 200 million EUR.
    *   **Net Debt** = Total Gross Debt - Cash - Cash Management Assets = 30,738 - 11,065 - 200 = 19,473 million EUR.

2.  **EBITDA**:
    *   S&P usually defines EBITDA as Operating Profit + Depreciation & Amortization.
    *   Profit Loss From Operating Activities (2021-01-01 - 2022-01-01): 4,438 million EUR.
    *   Adjustments For Depreciation And Amortisation Expense (2021-01-01 - 2022-01-01): 3,219 million EUR.
    *   EBITDA = 4,438 + 3,219 = 7,657 million EUR.

3.  **Calculation**:
    *   Ratio = Net Debt / EBITDA = 19,473 / 7,657 ≈ 2.543.

(Using the 2022 end-of-year data points to calculate the ratio as of the 2022 annual report):
*   Net Debt (end 2022): Bonds (20,425) + Other Borrowings (3,205) + Short-term (6,368) = 29,998 million EUR.
*   Cash & Equivalents (end 2022): 12,578 + 755 = 13,333 million EUR.
*   Net Debt = 16,665 million EUR.
*   EBITDA (2022): Profit Loss From Operating Activities (6,489) + Depreciation & Amortization (3,613) = 10,102 million EUR.
*   Ratio = 16,665 / 10,102 ≈ 1.649.

Given the instructions reflect the state of the entity at the end of 2022 (using the 2022 financial year performance), we use the 2022 figures.
