To estimate the S&P-adjusted FFO-to-debt ratio for Fortum Oyj for 2022, we follow the S&P methodology for the Power & Gas industry.

**1. Identify Industry:** Fortum Oyj is a major European energy company (Unregulated Power and Gas).

**2. Estimate Adjusted EBITDA:**
*   Reported EBITDA (Continuing Operations): 1,842,000,000 EUR.
*   The reported figure already reflects adjustments (e.g., Items Affecting Comparability: -593,000,000 EUR). S&P typically adjusts for non-recurring items. The Comparable EBITDA is 2,436,000,000 EUR. We use the Comparable EBITDA as the baseline to normalize recurring performance.
*   Adjusted EBITDA = 2,436,000,000 EUR.

**3. Estimate FFO:**
*   FFO = Adjusted EBITDA - Cash Interest - Cash Taxes.
*   Cash Interest (Interest Paid Classified As Operating Activities): 201,000,000 EUR.
*   Cash Taxes (Income Taxes Paid Refund Classified As Operating Activities): 167,000,000 EUR.
*   FFO = 2,436,000,000 - 201,000,000 - 167,000,000 = 2,068,000,000 EUR.

**4. Estimate Adjusted Debt:**
*   Total Reported Debt: Sum of "Other Noncurrent Financial Liabilities" (3,658M), "Noncurrent Derivative Financial Liabilities" (756M), "Other Current Financial Liabilities" (4,127M), "Current Derivative Financial Liabilities" (3,973M).
*   Reported Debt (2023-01-01 / Dec 31 2022) = 3,658,000,000 + 756,000,000 + 4,127,000,000 + 3,973,000,000 = 12,514,000,000 EUR.
*   Eligible Cash (Liquid Funds): 3,919,000,000 EUR.
*   Adjusted Debt = 12,514,000,000 - 3,919,000,000 = 8,595,000,000 EUR.

**5. Calculate FFO / Adjusted_Debt Ratio:**
*   Ratio = 2,068,000,000 / 8,595,000,000 = 0.2406049...

Rounding to four decimal places, we get 0.2406.
