FFO (funds from operations) can be estimated from operating cash flow before working-capital movements.

Using the cash-flow statement items for 2022:

- Cash flows from operating activities = 17,460,000,000
- Increase/decrease in working capital = 1,279,000,000

Estimated FFO:

FFO = CFO − working capital movement  
FFO = 17,460,000,000 − 1,279,000,000  
FFO = 16,181,000,000

Next, estimate net debt at 2022 year-end using financial debt less cash and liquid/current financial assets:

Debt components:
- Short-term borrowings = 4,446,000,000
- Current portion of long-term borrowings = 3,097,000,000
- Current lease liabilities = 884,000,000
- Long-term borrowings = 19,374,000,000
- Noncurrent lease liabilities = 4,067,000,000

Total debt = 31,868,000,000

Cash / financial asset offsets:
- Cash and cash equivalents = 10,155,000,000
- Current financial assets at fair value through profit or loss = 8,251,000,000
- Other current financial assets = 1,504,000,000
- Other noncurrent financial assets = 1,967,000,000

Total offsets = 21,877,000,000

Net debt = 31,868,000,000 − 21,877,000,000  
Net debt = 9,991,000,000

FFO / Net debt:

16,181,000,000 / 9,991,000,000 = 1.6196, or about 162%.
