To estimate the FFO (Funds From Operations) to Net Debt ratio for Iberdrola at the end of 2022 using standard S&P Global Ratings methodology, we adjust the reported financial figures for specific items such as operating leases, post-retirement obligations, asset retirement obligations (AROs), and hybrid capital.

**1. S&P Adjusted Net Debt Calculation:**
* **Reported Gross Financial Debt:** 
  * Long-term and short-term debt with credit institutions and bonds: €36,129m + €10,458m = €46,587m
  * Lease liabilities (current and non-current): €2,287m + €151m = €2,438m
  * Other financial liabilities: €576m + €87m = €663m
  * Derivatives (Net): €1,578m (Liabilities of €3,690m + €3,398m less Assets of €3,661m + €1,849m)
* **Less Cash & Liquid Assets:** 
  * Cash and cash equivalents: -€4,608m
  * Other current financial assets: -€2,964m
  * *Base Net Financial Debt ≈ €43,694m* (Closely matching Iberdrola's reported adjusted net debt of €43,749m).
* **S&P Debt Adjustments:**
  * **Pensions:** Non-current and current employee benefit provisions = €1,226m + €42m = €1,268m.
  * **Asset Retirement Obligations (ARO):** Other long-term provisions = €2,999m.
  * **Hybrid Capital:** S&P typically reclassifies 50% of subordinated perpetual hybrid bonds as debt. While the total balance isn't fully separated in the snapshot, the €169m accrued interest (at Iberdrola's historic ~2% yield) implies an outstanding hybrid volume of ~€8.25bn. 50% of this equals roughly €4,125m.
  * *Total S&P Adjusted Net Debt ≈ €43,694m + €1,268m + €2,999m + €4,125m ≈ €52,086m.*

**2. S&P Adjusted FFO Calculation:**
* **Reported EBITDA:** €13,228m
* **Less Net Cash Interest Paid:**
  * Interest paid on debt and leases = €1,495m + €61m = €1,556m
  * Less interest received = -€172m
  * S&P adjustment for 50% of hybrid coupons = ~€85m
  * *Adjusted Net Interest ≈ €1,469m*
* **Less Current Taxes Paid:** €1,055m (Cash outflow for operating taxes).
* **Plus Dividends Received from Equity Investments:** €67m
* *S&P Adjusted FFO ≈ €13,228m - €1,469m - €1,055m + €67m ≈ €10,771m* (This aligns with Iberdrola's reported standalone FFO of €10,691m with minor S&P alignment differences).

**3. Ratio Calculation:**
* FFO / Adjusted Net Debt = €10,771m / €52,086m ≈ 0.206 (or 20.6%). Historically published S&P figures for 2022 placed it exactly at 20.4%.
