I'll work through this step-by-step for ITALGAS S.P.A. for fiscal year 2022 (the period 2022-01-01 to 2023-01-01).

## Step 1: Identify the Relevant Industry

ITALGAS S.P.A. is Italy's largest natural gas distribution company. It operates regulated gas distribution networks. This falls squarely under **Regulated Utilities** (Gas subsector).

## Step 2: Estimate Adjusted EBITDA

First, let me reconstruct EBITDA from the income statement:

**Operating Profit (EBIT):** 641,338,000 EUR
**D&A:** 479,186,000 EUR (Depreciation Amortisation And Impairment Loss)

**EBITDA = EBIT + D&A = 641,338,000 + 479,186,000 = 1,120,524,000 EUR**

**S&P Adjustments:**

- **Lease adjustments:** S&P typically adds back operating lease costs and adds an imputed depreciation. Looking at the cash flow statement, "Cash Outflow For Leases" = 27,865,000 EUR. The short-term financial liabilities include lease-related items. The balance sheet shows lease-related financial liabilities. For S&P, operating leases are capitalized. The lease payment of ~27,865,000 is split into interest and depreciation. The EBITDA adjustment would add back the interest portion of leases. Looking at the financial liabilities, I can see lease-related items in "Other Current Financial Liabilities" (290,000) and "Other Noncurrent Financial Liabilities" (34,000 in 2023 vs 6,283,000 in 2022). These seem small. The lease cash outflow suggests IFRS 16 is already applied, so leases are already capitalized on balance sheet. Under IFRS 16, the D&A already includes lease depreciation, and finance costs include lease interest. S&P would add back the lease interest portion to EBITDA. Let me estimate: with total lease-related liabilities around 6,573,000 (6,283+290) at start of year, interest might be small (~2-3%). I'll estimate lease interest at approximately 200,000 EUR (small).

- **Pension adjustments:** S&P adds back the service cost and adds the interest cost on pension obligations. The employee benefits liability decreased from 95,648,000 to 69,917,000. The cash flow adjustments show "Adjustments For Increase Decrease In Employee Benefit Liabilities" = -17,574,000. Without detailed pension breakdown, I'll note this but the impact on EBITDA is typically modest.

- **Share-based payments:** Already included in operating expenses (non-cash), these are typically left in EBITDA by S&P.

For simplicity and given the data available, I'll use:

**Adjusted EBITDA ≈ 1,120,524,000 + ~200,000 (lease interest) ≈ 1,120,724,000 EUR**

I'll round to approximately **1,120,700,000 EUR**.

## Step 3: Estimate FFO

**FFO = Adjusted_EBITDA - cash_interest - cash_taxes**

**Cash interest paid:** 53,720,000 EUR (from cash flow statement) + lease interest (~200,000) = ~53,920,000

Actually, S&P's FFO uses cash interest on all debt including leases. The reported "Finance Costs Paid Classified As Operating Activities" = 53,720,000 already likely includes lease interest under IFRS 16.

**Cash taxes paid:** 152,372,000 EUR (from cash flow statement)

**FFO = 1,120,700,000 - 53,720,000 - 152,372,000 = 914,608,000 EUR**

## Step 4: Estimate Adjusted Debt

**Reported debt:**
- Short-term financial liabilities: 142,437,000
- Long-term financial liabilities: 6,402,913,000
- Total reported debt: 6,545,350,000

**Lease obligations:** Already included in financial liabilities under IFRS 16 (Other current/noncurrent financial liabilities: 290,000 + 34,000 = 324,000). These are already in the debt figures above.

**Pension deficit:** 69,917,000 EUR (Noncurrent Provisions For Employee Benefits)

**Surplus cash deduction:** S&P typically doesn't net cash for utilities unless there's a specific reason. For regulated utilities, minimal cash is deducted. I'll not subtract significant cash.

**Adjusted Debt = 6,545,350,000 + 69,917,000 = 6,615,267,000 EUR**

## Step 5: Calculate FFO / Adjusted Debt

**FFO / Adjusted_Debt = 914,608,000 / 6,615,267,000 = 0.13826**

Rounding to four decimal places:
