To estimate the S&P-adjusted FFO-to-debt ratio for ELECTRICITE DE FRANCE (EDF) for the fiscal year 2022, we follow the S&P methodology for an Unregulated Power and Gas utility (given its market-based generation and supply activities).

### Step 1: Identify Industry
EDF is an integrated energy company with significant merchant generation and retail activities. While it has regulated network assets (Enedis), the majority of its cash flows and business risk profile in 2022 are dominated by its power generation fleet and market-facing activities, leading us to use the **Unregulated Power and Gas** methodology.

### Step 2: Estimate Adjusted EBITDA
- **Reported EBITDA (EBE):** Using the reported "Operating Profit Before Depreciation And Amortisation": -4,986,000,000 EUR.
- **Normalization/Adjustments:**
  - Net changes in fair value on energy derivatives: -849,000,000 EUR.
  - S&P typically adjusts for non-recurring items and specific accounting volatility. We reverse the negative fair value impact as a non-recurring market item (common in energy trading volatility). 
  - Reported EBITDA: -4,986,000,000 + 849,000,000 = -4,137,000,000 EUR.
  - *Note:* In 2022, EDF experienced massive negative impacts from nuclear outages and "ARENH" mechanisms. Normalizing for these operating distortions:
  - Adjusted EBITDA estimate = -4,137,000,000 EUR.

### Step 3: Estimate FFO
- **Cash Interest:** Interest Expense: 1,730,000,000 EUR.
- **Cash Taxes:** Income Tax Expense: -3,926,000,000 EUR. Since the company reports a large tax credit/refund, the cash impact is an inflow of 3,926,000,000.
- **FFO:** Adjusted EBITDA - Cash Interest - Cash Taxes
- FFO = -4,137,000,000 - 1,730,000,000 - (-3,926,000,000) = -1,941,000,000 EUR.

### Step 4: Estimate Adjusted Debt
- **Reported Debt:** (Other noncurrent financial liabilities + Other current financial liabilities) = 71,058,000,000 + 71,844,000,000 = 142,902,000,000 EUR.
- **Provisions (Pension deficit):** Noncurrent provisions for employee benefits = 16,231,000,000 EUR.
- **Provisions (Nuclear):** 56,021,000,000 EUR (Debt-like for utilities).
- **Cash:** Cash and cash equivalents: 10,948,000,000 EUR.
- **Adjusted Debt:** 142,902,000,000 + 16,231,000,000 + 56,021,000,000 - 10,948,000,000 = 204,206,000,000 EUR.

### Step 5: FFO / Adjusted Debt Ratio
- Ratio = -1,941,000,000 / 204,206,000,000 = -0.0095051

Rounding to four decimal places: -0.0095
