Let’s reason through this.

**Step 1 – Estimate FFO (Funds From Operations)**  
FFO is generally defined as **Cash Flow from Operations before changes in working capital**. From the data:

- **Cash Flows From Operating Activities (2022)**: 17,460,000,000 EUR  
- We have an explicit line: **Increase Decrease in Working Capital (2022)** = 1,279,000,000 EUR

So:  
FFO = Cash from Operations − Changes in Working Capital  
FFO = 17,460,000,000 − 1,279,000,000 = **16,181,000,000 EUR**

**Step 2 – Calculate Net Debt**  
Net debt = Total debt − Cash and cash equivalents

Debt components at **2023-01-01** (end of 2022):  
- 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 = 4,446 + 3,097 + 884 + 19,374 + 4,067 = **31,868,000,000 EUR**

Cash and cash equivalents at end of 2022 (from the statement of financial position) = **10,155,000,000 EUR** (the "If Different" figure is only for cash flow statement purpose, so I use the balance sheet one).

Net debt = 31,868,000,000 − 10,155,000,000 = **21,713,000,000 EUR**

**Step 3 – FFO / Net Debt**  
Ratio = 16,181,000,000 / 21,713,000,000 ≈ **0.745**
