I'll work through this step-by-step for Iberdrola SA for fiscal year 2022 (the period 2022-01-01 to 2023-01-01).

## Step 1: Identify the relevant industry

Iberdrola is a major integrated utility company with significant regulated networks (electricity transmission and distribution) and unregulated power generation (including renewables). It's a multi-utility that fits primarily under **Regulated Utilities** with significant unregulated power operations. I'll apply the regulated utilities methodology as the primary framework.

## Step 2: Estimate Adjusted EBITDA

**Reported EBITDA:**
The company reports "Beneficio Bruto De Explotacion Ebitda" = €13,228M for 2022-01-01 to 2023-01-01.

**Lease adjustments:**
S&P typically adds back lease-related expenses to EBITDA. The right-of-use assets are €2,370M and lease liabilities (current + noncurrent) = €151M + €2,287M = €2,438M. The lease interest component is reported in the cash flow statement: "Intereses Pagados Excluidos Intereses Capitalizados De Pasivos Financieros Por Arrendamiento" = €61M. The depreciation on ROU assets can be estimated. S&P adds operating lease rent back and treats it as a financing item. The total lease payment = principal (€175M) + interest (€61M) = €236M. This is already embedded in EBITDA partially. S&P adjustment adds the depreciation portion of leases back to EBITDA. However, since IFRS 16 is already applied (leases are capitalized), the EBITDA already excludes lease depreciation and interest. Under S&P methodology, EBITDA under IFRS 16 already captures the lease adjustment implicitly. No additional lease adjustment to EBITDA is needed since IFRS 16 capitalizes leases.

**Operating lease adjustment to EBITDA:** Under S&P's approach with IFRS 16 already applied, EBITDA already reflects the lease treatment. No further adjustment needed.

**Pension adjustments:**
Noncurrent pension provisions = €1,226M (2023-01-01) vs €1,592M (2022-01-01). The pension deficit is captured in debt adjustments. For EBITDA, S&P typically adjusts for the difference between pension expense and cash contributions, but without detailed data, I'll use reported EBITDA.

**Adjusted_EBITDA ≈ €13,228M**

## Step 3: Estimate FFO

**Cash interest:**
From the cash flow statement:
- Interest paid on debt: €1,495M
- Interest paid on leases: €61M
- Interest capitalized: €189M (paid as investing)
- Hybrid interest: €169M (subordinated perpetual bonds - but S&P treats hybrid interest differently)

Total cash interest (S&P basis) = €1,495M + €61M + €189M = €1,745M

However, S&P typically includes capitalized interest in cash interest. For hybrid instruments, S&P gives partial equity credit, so I'll exclude hybrid interest from FFO deduction since it's equity-like (addressed in debt adjustment).

Cash interest = €1,495M + €61M + €189M = €1,745M

**Cash taxes:**
"Income Taxes Paid Classified As Operating Activities" = €1,055M

**FFO = 13,228 - 1,745 - 1,055 = €10,428M**

## Step 4: Estimate Adjusted Debt

**Reported financial debt:**
- NC bank debt & bonds: €36,129M
- Current bank debt & bonds: €10,458M
- Total reported debt = €46,587M

**Lease liabilities:** €2,287M + €151M = €2,438M (already on balance sheet under IFRS 16)

**Pension deficit:** €1,226M (noncurrent) + €42M (current) = €1,268M. S&P typically adjusts for post-tax pension deficit. Using ~75% factor: €1,268M × 0.75 ≈ €951M

**Hybrid instruments (equity content instruments on BS):**
"Instrumentos De Capital Con Caracteristicas De Pasivo Financiero": NC €576M + C €87M = €663M
Plus subordinated perpetual bonds in NCI (~€2,750M issued in prior year, still outstanding, shown in noncontrolling interests). S&P typically gives 50% equity credit to hybrids, meaning 50% is debt. For the on-BS hybrids: 50% × €663M = €332M debt portion.

**Surplus cash deduction:**
Cash = €4,608M. S&P typically deducts readily available cash. Conservative estimate: minimal deduction for operating needs. Deduct ~€4,000M.

**Other financial liabilities:** €1,534M + €5,058M includes collateral and other items - not all debt-like. I'll exclude derivatives and trade payables.

**Adjusted_Debt = 46,587 + 2,438 + 951 + 332 - 4,000 = €46,308M**

## Step 5: Calculate FFO/Adjusted Debt

**FFO / Adjusted_Debt = 10,428 / 46,308 = 0.2252**
