To estimate the S&P-adjusted FFO-to-debt ratio for Acciona SA for the fiscal year 2022, we follow the prescribed workflow:

### 1. Identify Industry
Acciona SA is a Spanish conglomerate heavily involved in renewable energy (Acciona Energía), water management, and large infrastructure projects. Following S&P methodology for corporate issuers, we treat its diversified operations primarily through a corporate lens, ensuring we include standard adjustments for leases and cash.

### 2. Estimate Adjusted_EBITDA
*   **Reported Profit from Operating Activities:** 1,334,000,000 EUR
*   **Add: Dotación amortización y variación de provisiones:** 762,000,000 EUR
*   **EBITDA (approx):** 2,096,000,000 EUR
*   *Note:* S&P typically adds back lease expenses. We have lease payments:
    *   Interest portion (Finance costs include lease interest): 256,000,000 (total).
    *   Principal portion of leases (financing cash flows): 120,000,000 EUR.
*   **Adjusted_EBITDA:** 2,096,000,000 + 120,000,000 (approx. rental/lease impact) = 2,216,000,000 EUR.

### 3. Estimate FFO
*   **Adjusted_EBITDA:** 2,216,000,000 EUR
*   **Cash Interest:** 209,000,000 EUR (Interest paid classified as operating activities)
*   **Cash Taxes:** 215,000,000 EUR
*   **FFO:** 2,216,000,000 - 209,000,000 - 215,000,000 = 1,792,000,000 EUR

### 4. Estimate Adjusted_Debt
*   **Reported Debt (Noncurrent + Current Loans):**
    *   Noncurrent loans received: 2,624,000,000
    *   Current loans received: 553,000,000
    *   Other noncurrent financial liabilities (Participaciones): 3,101,000,000
    *   Other current financial liabilities (Participaciones): 1,139,000,000
    *   Total: 7,417,000,000 EUR
*   **Lease Liabilities:** 439,000,000 (noncurrent) + 72,000,000 (current) = 511,000,000 EUR
*   **Gross Debt:** 7,417,000,000 + 511,000,000 = 7,928,000,000 EUR
*   **Less Eligible Cash:** Cash and Cash Equivalents (2,360,000,000)
*   **Adjusted_Debt:** 7,928,000,000 - 2,360,000,000 = 5,568,000,000 EUR

### 5. Calculate Ratio
*   **FFO / Adjusted_Debt:** 1,792,000,000 / 5,568,000,000 = 0.321839...

Rounding to four decimal places, we get 0.3218.
