To estimate the S&P-adjusted FFO-to-debt ratio for Red Eléctrica Corporación, S.A. (Redeia) for 2022, we follow the steps outlined:

### 1. Identify Industry
Redeia is a regulated transmission utility (power sector), fitting the **Regulated Utilities** methodology.

### 2. Estimate Adjusted EBITDA
- **EBITDA Calculation:**
  - Operating Profit (Profit from Operating Activities): 961,554,000 EUR
  - Depreciation and Amortization: 544,992,000 EUR
  - EBITDA = 961,554,000 + 544,992,000 = 1,506,546,000 EUR
- **Adjustments:** We assume no significant non-recurring items or lease adjustments based on provided data.
- **Adjusted_EBITDA = 1,506,546,000 EUR**

### 3. Estimate FFO (Funds From Operations)
- **Cash Interest:** The report provides "Interest Paid Classified As Operating Activities" = 123,524,000 EUR.
- **Cash Taxes:** The report provides "Income Taxes Paid Refund Classified As Operating Activities" = 363,996,000 EUR.
- **FFO** = Adjusted_EBITDA - Cash Interest - Cash Taxes
- FFO = 1,506,546,000 - 123,524,000 - 363,996,000 = 1,019,026,000 EUR

### 4. Estimate Adjusted Debt
- **Reported Debt:**
  - Noncurrent Financial Liabilities: 5,543,755,000 EUR
  - Current Financial Liabilities: 1,705,277,000 EUR
  - Total Debt = 7,249,032,000 EUR
- **Eligible Cash:** "Cash And Cash Equivalents" = 794,824,000 EUR (using 2022-12-31 figures as 2023-01-01).
- **Adjusted_Debt** = Total Debt - Cash
- Adjusted_Debt = 7,249,032,000 - 794,824,000 = 6,454,208,000 EUR

### 5. Calculate Ratio
- FFO / Adjusted_Debt = 1,019,026,000 / 6,454,208,000 = 0.157885...

Rounding to four decimal places: 0.1579
