To estimate the leverage trend, we must calculate the Net Debt / EBITDA ratio for 2021 (for the 2022 calculation) and 2022 (for the 2023 calculation).

**1. Definitions:**
*   **Net Debt:** (Short Term Financial Liabilities + Long Term Financial Liabilities) - Cash And Cash Equivalents.
*   **EBITDA:** Profit Loss From Operating Activities + Depreciation Amortisation And Impairment Loss.

**2. Data for 2021 (Year end 2022-01-01):**
*   Short Term Financial Liabilities (Excl. Other): 591,188,000
*   Other Current Financial Liabilities: 290,000
*   Long Term Financial Liabilities (Excl. Other): 5,785,707,000
*   Other Noncurrent Financial Liabilities: 6,283,000
*   Total Liabilities: 591,188,000 + 290,000 + 5,785,707,000 + 6,283,000 = 6,383,468,000
*   Cash: 1,391,763,000
*   Net Debt 2021: 6,383,468,000 - 1,391,763,000 = 4,991,705,000
*   EBITDA 2021: 583,231,000 (Operating Profit) + 445,251,000 (Depreciation/Amortization) = 1,028,482,000
*   Ratio 2021: 4,991,705,000 / 1,028,482,000 ≈ 4.85x

**3. Data for 2022 (Year end 2023-01-01):**
*   Short Term Financial Liabilities (Excl. Other): 142,437,000
*   Other Current Financial Liabilities: 290,000
*   Long Term Financial Liabilities (Excl. Other): 6,402,913,000
*   Other Noncurrent Financial Liabilities: 34,000
*   Total Liabilities: 142,437,000 + 290,000 + 6,402,913,000 + 34,000 = 6,545,674,000
*   Cash: 451,946,000
*   Net Debt 2022: 6,545,674,000 - 451,946,000 = 6,093,728,000
*   EBITDA 2022: 641,338,000 (Operating Profit) + 479,186,000 (Depreciation/Amortization) = 1,120,524,000
*   Ratio 2022: 6,093,728,000 / 1,120,524,000 ≈ 5.44x

**4. Trend Assessment:**
*   Gap: 5.44 - 4.85 = 0.59x
*   Since the gap is higher than 0.3x, the trend is considered deteriorating.
