To estimate S&P-style adjusted leverage trend, use:

Net Debt / EBITDA

Approximate net debt from reported borrowings and cash:

For 2022 balance sheet date, i.e. 2023-01-01:
- Long-term borrowings: 5,491.124m
- Current borrowings and current portion of noncurrent borrowings: 721.845m
- Cash and cash equivalents: 794.824m
- Net debt = 5,491.124 + 721.845 - 794.824 = 5,418.145m

For 2021 balance sheet date, i.e. 2022-01-01:
- Long-term borrowings: 5,896.170m
- Current borrowings and current portion of noncurrent borrowings: 1,391.722m
- Cash and cash equivalents: 1,574.427m
- Net debt = 5,896.170 + 1,391.722 - 1,574.427 = 5,713.465m

Approximate EBITDA as operating profit plus depreciation and amortisation:

For 2022:
- Operating profit: 961.554m
- Depreciation and amortisation: 544.992m
- EBITDA = 1,506.546m
- Net Debt / EBITDA = 5,418.145 / 1,506.546 = 3.60x

For 2021:
- Operating profit: 991.970m
- Depreciation and amortisation: 522.114m
- EBITDA = 1,514.084m
- Net Debt / EBITDA = 5,713.465 / 1,514.084 = 3.77x

Year-on-year change:
- 2022 ratio minus 2021 ratio = 3.60x - 3.77x = -0.18x

Since leverage decreased by less than 0.3x, under the stated rule this is classified as Stable.
