**Step 1: Identify the relevant industry for "ENGIE"**
ENGIE is a major integrated energy company involved in electricity generation, gas distribution, and related services. Given its operations in regulated utilities, unregulated power and gas, and energy infrastructure, we classify it under the "Regulated Utilities" / "Unregulated Power And Gas" sector methodologies, but for the calculation of financial metrics, we rely on the standard corporate methodology baseline formulas provided, incorporating typical energy sector adjustments.

**Step 2: Estimate "Adjusted_EBITDA"**
Using the baseline formula: 
Adjusted_EBITDA = EBITDA (reported or reconstructed) + adjustment_leases + nonrecurring_losses - nonrecurring_gains ± pension_adjustments ± joint_venture_proportional_EBITDA ± other_normalization_adjustments

1. **EBITDA (reconstructed):** We calculate this starting from Current Operating Income Including Operating Mtm And Share In Net Income Of Equity Method Entities (which represents EBIT).
   - EBIT (2022): 5,367,000,000 EUR
   - Add back Depreciation Amortization And Provisions: 5,187,000,000 EUR
   - Reconstructed EBITDA = 5,367,000,000 + 5,187,000,000 = 10,554,000,000 EUR.

2. **Nonrecurring_losses / nonrecurring_gains:**
   - Impairment losses: 2,774,000,000 EUR (Added back as non-recurring loss)
   - Restructuring expenses: 230,000,000 EUR (Added back as non-recurring loss)
   - Other non-recurring items: -1,328,000,000 EUR (Subtracted as non-recurring gain, since it's a negative expense representing a net gain)
   - Total non-recurring adjustment = 2,774,000,000 + 230,000,000 - 1,328,000,000 = 1,676,000,000 EUR.

3. **Joint Venture Proportional EBITDA:** ENGIE already includes the share of net income in its EBIT. To proportionally consolidate the EBITDA of these JVs, we add back the depreciation of the JVs. Since this isn't explicitly provided, we use a standard utility sector estimate of 40% D&A to EBITDA margin for JVs. 
   - JV Net Income: 1,059,000,000 EUR
   - Estimated JV EBITDA = 1,059,000,000 / 0.6 = 1,765,000,000 EUR.
   - JV EBITDA to add = 1,765,000,000 - 1,059,000,000 = 706,000,000 EUR.

4. **Pension Adjustments / Lease Adjustments:** No specific deficits or operating lease right-of-use asset values are reported in the balance sheet facts to quantify these adjustments, so we omit them (0 EUR).

Adjusted_EBITDA = 10,554,000,000 + 1,676,000,000 + 706,000,000 = 12,936,000,000 EUR.

**Step 3: Estimate "FFO"**
Using the baseline formula:
FFO = Adjusted_EBITDA - cash_interest - cash_taxes

1. **Cash Interest:** Taken from "Interest Paid Classified As Financing Activities" plus "Cash Flow On Derivatives Qualifying As Net Investment Hedges...".
   - Cash Interest = 822,000,000 + 216,000,000 = 1,038,000,000 EUR.

2. **Cash Taxes:** Taken from "Income Taxes Paid Refund Classified As Operating Activities".
   - Cash Taxes = 1,504,000,000 EUR.

FFO = 12,936,000,000 - 1,038,000,000 - 1,504,000,000 = 10,394,000,000 EUR.

**Step 4: Estimate "Adjusted_Debt"**
Using the baseline formula:
Adjusted_Debt = (reported_debt + leases + pension_deficit + guarantees + hybrid_debt_portion + other_debt_like_items) - eligible_cash

1. **Reported Debt:** Sum of Long-term Borrowings and Current Borrowings.
   - Long-term Borrowings (2022): 30,458,000,000 EUR
   - Current Borrowings (2022): 10,590,000,000 EUR
   - Total Reported Debt = 30,458,000,000 + 10,590,000,000 = 41,048,000,000 EUR.

2. **Hybrid Debt Portion:** ENGIE has "Deeply Subordinated Perpetual Notes" classified under Equity. S&P typically treats 50% of such hybrid instruments as debt.
   - Deeply Subordinated Perpetual Notes (2022): 3,767,000,000 EUR
   - Hybrid Debt Addition = 3,767,000,000 * 50% = 1,883,500,000 EUR.

3. **Other items / Leases / Pension Deficit:** Not provided/quantifiable, assumed 0.

4. **Eligible Cash:** We deduct surplus cash. Given ENGIE's size, we apply the standard 5% of reported debt as necessary working cash, deducting the rest.
   - Cash And Cash Equivalents (2022): 13,890,000,000 EUR
   - Eligible Cash to deduct = 13,890,000,000 - (41,048,000,000 * 0.05) = 13,890,000,000 - 2,052,400,000 = 11,837,600,000 EUR.

Adjusted_Debt = 41,048,000,000 + 1,883,500,000 - 11,837,600,000 = 31,093,900,000 EUR.

**Step 5: Calculate "FFO / Adjusted_Debt" ratio**
FFO / Adjusted_Debt = 10,394,000,000 / 31,093,900,000 = 0.3341839...

Rounding to four decimal places, we get 0.3342.
