To estimate the Funds From Operations (FFO) to Net Debt ratio for 2022 based on S&P methodology, I will follow these steps:

1.  **Calculate Funds From Operations (FFO)**:
    *   S&P's FFO typically starts with Profit/Loss from Operating Activities and adjusts for depreciation, amortization, impairments, and other non-cash items.
    *   From the data:
        *   Profit Loss From Operating Activities 2022 = 1,334,000,000 EUR
        *   We need to add back "Dotacion Amortizacion YVariacion De Provisiones" (Depreciation, Amortization, and Provisions) = 762,000,000 EUR
        *   We also adjust for Impairment Loss Reversal = -15,000,000 EUR (This is an impairment reversal/gain, which should be subtracted from operating profit, or if we are adding back total D&A including impairments, we need to net it out. Since "Dotacion..." includes provisions but the impairment line is separate, we add back the main depreciation line and subtract the impairment reversal).
        *   Resultado De Puesta En Equivalencia Operativa = 159,000,000 EUR (This is equity income from operations, which is non-cash, so we subtract it to get cash-based FFO).
        *   Other Gains Losses = 13,000,000 EUR (Non-operating, non-cash, subtract if gain).
    *   FFO Calculation:
        *   Operating Profit: 1,334
        *   + Depreciation/Amortization/Provisions: 762
        *   - Impairment Reversal: 15
        *   - Equity Income from Operations: 159
        *   - Other Gains: 13
        *   FFO = 1,334 + 762 - 15 - 159 - 13 = 1,909,000,000 EUR

2.  **Calculate Net Debt**:
    *   S&P's Net Debt = Total Debt - Cash and Cash Equivalents.
    *   Total Debt = Noncurrent + Current portions of debt and leases.
    *   From the data:
        *   Noncurrent Debt/Loans/Leases:
            *   "Participaciones Preferentes Obligaciones YOtros Valores Negociables No Corrientes1" (Noncurrent Marketable Securities/Bonds) = 3,101,000,000
            *   "Noncurrent Portion Of Noncurrent Loans Received" = 2,624,000,000
            *   "Noncurrent Lease Liabilities" = 439,000,000
        *   Current Debt/Loans/Leases:
            *   "Participaciones Preferentes Obligaciones YOtros Valores Negociables Corrientes" (Current Marketable Securities/Bonds) = 1,139,000,000
            *   "Current Loans Received And Current Portion Of Noncurrent Loans Received" = 553,000,000
            *   "Current Lease Liabilities" = 72,000,000
    *   Total Debt = 3,101 + 2,624 + 439 + 1,139 + 553 + 72 = 7,928,000,000 EUR
    *   Cash and Cash Equivalents = 2,360,000,000 EUR
    *   Net Debt = 7,928,000,000 - 2,360,000,000 = 5,568,000,000 EUR

3.  **Calculate FFO / Net Debt**:
    *   FFO / Net Debt = 1,909,000,000 / 5,568,000,000
    *   FFO / Net Debt = 0.3428
