To estimate the S&P-adjusted FFO-to-debt ratio for ENI S.P.A. for 2022, we follow the S&P Global Ratings Corporate Methodology and the provided baseline formulas:

**1. Adjusted EBITDA**
We start by reconstructing the base EBITDA from the income statement, then apply the specified S&P adjustments:
*   **Reported Profit / Loss:** €13,961 million
*   **Income Tax Expense:** €8,088 million
*   **Net Finance Cost:** €925 million (using "Finance Income Cost" of -€925 million)
*   **Depreciation and Amortisation (D&A):** €7,205 million
*   *Base Reconstructed EBITDA = 13,961 + 8,088 + 925 + 7,205 = €30,179 million*

Next, we apply the prescribed adjustments:
*   **Nonrecurring Losses:** Add "Impairment Loss Reversal Of Impairment Loss Recognised In Profit Or Loss" (€1,140 million) and "Write Off Of Tangible And Intangible Assets" (€599 million).
*   **Joint Venture / Equity Income:** S&P excludes equity-accounted profits and includes cash dividends received. We deduct "Share Of Profit Loss Of Equity Accounted Investments" (-€1,841 million) and add "Dividends Received Classified As Operating Activities" (+€1,545 million). 
*   **Other Normalization Adjustments:** We deduct non-operating "Other Income Expense From Investments" (-€3,623 million) to arrive at a purely operating figure.
*   *Adjusted EBITDA = 30,179 + 1,140 + 599 - 1,841 + 1,545 - 3,623 = €27,999 million*

**2. Funds From Operations (FFO)**
Using the given baseline formula, we deduct cash interest and cash taxes from Adjusted EBITDA:
*   **Cash Interest Paid:** €851 million (from "Interest Paid Classified As Operating Activities")
*   **Cash Taxes Paid:** €8,488 million (from "Income Taxes Paid Refund Classified As Operating Activities")
*   *FFO = 27,999 - 851 - 8,488 = €18,660 million*

**3. Adjusted Debt**
We sum the reported financial debt and add debt-like obligations, then net the eligible cash:
*   **Reported Debt:** "Shortterm Borrowings" (€4,446 million) + "Current Portion Of Longterm Borrowings" (€3,097 million) + "Longterm Borrowings" (€19,374 million) = €26,917 million
*   **Leases:** "Current Lease Liabilities" (€884 million) + "Noncurrent Lease Liabilities" (€4,067 million) = €4,951 million 
*   **Pension Deficit:** "Noncurrent Provisions For Employee Benefits" = €786 million
*   **Hybrid Debt Portion:** ENI issued €3,000 million (2020) and €2,000 million (2021) in perpetual subordinated bonds (hybrids). S&P treats 50% of intermediate-equity-content hybrids as debt = €2,500 million
*   **Other Debt-like Items:** For Oil & Gas E&P companies, Asset Retirement Obligations (AROs) are a major debt-like item. We include "Other Longterm Provisions" which strictly accounts for these long-term decommissioning liabilities = €15,267 million
*   **Eligible Cash:** "Cash And Cash Equivalents" (€10,155 million) + "Current Financial Assets At Fair Value Through P&L" (€8,251 million) + "Other Current Financial Assets" (€1,504 million) = €19,910 million
*   *Adjusted Debt = 26,917 + 4,951 + 786 + 2,500 + 15,267 - 19,910 = €30,511 million*

**4. FFO-to-Debt Ratio**
*   *FFO / Adjusted Debt = 18,660 / 30,511 = 0.61158...*
