I'll work through this step-by-step for BOUYGUES.

## Step 1: Identify the relevant industry for "BOUYGUES"

BOUYGUES is a French diversified conglomerate with operations in construction, media (TF1), and telecom (Bouygues Telecom). It does not fit into any of the specific industry methodologies provided (Regulated Utilities, Oil and Gas E&P, Unregulated Power and Gas, or Transportation Infrastructure). 

Therefore, I will apply the **general corporate baseline formulas**.

## Step 2: Estimate Adjusted_EBITDA

First, let me reconstruct EBITDA from the available data.

From the income statement items for 2022 (2022-01-01 to 2023-01-01):
- Revenue From Contracts With Customers: 44,322,000,000 EUR
- Other Revenue: 76,000,000 EUR
- Total Revenue: 44,398,000,000 EUR

Expenses:
- Raw Materials And Consumables Used: 19,372,000,000 EUR
- Employee Benefits Expense: 10,381,000,000 EUR
- Services Expense: 10,572,000,000 EUR
- Tax Expense Other Than Income Tax Expense: 639,000,000 EUR
- Depreciation And Amortisation Expense: 2,228,000,000 EUR
- Depreciation Rightofuse Assets: 446,000,000 EUR
- Impairment Loss Reversal Of Impairment Loss Recognised In Profit Or Loss And Provision Expense: 172,000,000 EUR
- Changes In Inventories Of Finished Goods And Work In Progress: -61,000,000 EUR
- Other Income Recurring: 2,565,000,000 EUR
- Other Expense By Nature Recurring: 1,252,000,000 EUR

Profit Loss From Operating Activities Recurring: 1,962,000,000 EUR
Profit Loss From Operating Activities: 1,872,000,000 EUR

Let me verify: Operating profit (recurring) = Revenue - operating expenses + other income

Let me reconstruct EBITDA:
- Profit Loss From Operating Activities: 1,872,000,000 EUR
- Add back: Depreciation And Amortisation Expense: 2,228,000,000 EUR
- Add back: Depreciation Rightofuse Assets: 446,000,000 EUR

EBITDA = 1,872,000,000 + 2,228,000,000 + 446,000,000 = 4,546,000,000 EUR

Wait - let me check if depreciation is already included in operating profit. Looking at the structure, "Profit Loss From Operating Activities" should be after depreciation but before interest and taxes.

Actually, let me verify using the recurring operating profit:
Profit Loss From Operating Activities Recurring: 1,962,000,000 EUR

Add: Depreciation And Amortisation Expense: 2,228,000,000 EUR
Add: Depreciation Rightofuse Assets: 446,000,000 EUR

EBITDA (recurring) = 1,962,000,000 + 2,228,000,000 + 446,000,000 = 4,636,000,000 EUR

But we need to check if there are non-recurring items. The difference between recurring and total operating profit:
1,962,000,000 - 1,872,000,000 = 90,000,000 EUR

This is due to:
Other Operating Income Non Recurring: 93,000,000 EUR
Other Operating Expense Non Recurring: 183,000,000 EUR
Net non-recurring expense: 90,000,000 EUR

For S&P purposes, we typically use recurring EBITDA, so:
EBITDA = 4,636,000,000 EUR

Now for adjustments:
- **Lease adjustment**: Under S&P methodology, we add back operating lease expenses and subtract depreciation of right-of-use assets. However, with IFRS 16, leases are already capitalized. The standard S&P adjustment for IFRS 16 leases is to add back the lease liability interest and depreciation, then subtract an "as-if" operating lease expense (typically 1/3 of total lease payments as interest, 2/3 as depreciation proxy, or using the EBITDA pre-IFRS 16 approach).

Actually, for S&P's Adjusted EBITDA with IFRS 16, they typically:
- Add back depreciation of right-of-use assets (already in my calculation)
- Add back interest on lease liabilities (part of interest expense)

But for EBITDA, since it's pre-interest anyway, the main adjustment is to treat leases as operating for debt purposes.

For EBITDA itself under general corporate methodology, S&P typically uses reported EBITDA with IFRS 16 (i.e., including the depreciation add-back), but makes debt adjustments.

Let me recalculate more carefully:
- Operating profit (EBIT): 1,872,000,000 EUR
- Add: Depreciation and amortization: 2,228,000,000 EUR
- Add: Depreciation of right-of-use assets: 446,000,000 EUR

EBITDA = 1,872,000,000 + 2,228,000,000 + 446,000,000 = 4,546,000,000 EUR

Wait, I need to check if the 2,228,000,000 includes right-of-use depreciation or not. Looking at the data, "Depreciation And Amortisation Expense" and "Depreciation Rightofuse Assets" are separate line items. So total depreciation = 2,228,000,000 + 446,000,000 = 2,674,000,000 EUR.

But actually, for EBITDA calculation from operating profit:
EBITDA = Operating profit + depreciation and amortization (all types)

So EBITDA = 1,872,000,000 + 2,228,000,000 + 446,000,000 = 4,546,000,000 EUR

For non-recurring items, S&P adjusts for non-recurring losses (add back) and non-recurring gains (subtract). The net non-recurring expense is 90,000,000 EUR (expense of 183M minus income of 93M). Since this is a net loss, we add it back for Adjusted EBITDA:

Adjusted_EBITDA = 4,546,000,000 + 90,000,000 = 4,636,000,000 EUR

This matches the recurring operating profit approach.

Lease adjustment: Under S&P methodology for general corporates with IFRS 16, the typical EBITDA adjustment is to add back the full lease expense as if operating leases were still off-balance sheet, then subtract only the "depreciation" portion. Actually, the standard approach is:

For pre-IFRS 16 EBITDA: Add back operating lease expense (not depreciation of ROU assets)

With IFRS 16 already applied, S&P sometimes uses a "hybrid" approach where they calculate what operating lease expense would have been. However, for general corporates, S&P often accepts reported EBITDA with IFRS 16 but adjusts debt.

Actually, looking more carefully at S&P methodology: For general corporates, the standard Adjusted EBITDA formula is:
- Reported EBITDA
- Plus/minus non-recurring items
- Plus/minus other normalization adjustments

For leases specifically, S&P's general approach is to adjust debt for leases but not typically adjust EBITDA for IFRS 16 beyond what's already in reported numbers.

However, there is a specific adjustment: S&P adds back the interest on lease liabilities to EBITDA (since it's part of "cost of net debt" that's below operating profit, but wait - under IFRS 16, lease interest is already below operating profit).

Let me check: Interest Expense On Lease Liabilities: 62,000,000 EUR - this is below operating profit.

So EBITDA already excludes lease interest. The depreciation of ROU assets (446M) is already added back in my EBITDA calculation.

For S&P's standard approach with IFRS 16: they typically use reported EBITDA (which includes the benefit of not having operating lease expense) but then add lease liabilities to debt.

However, some S&P methodologies for specific industries mention adding back lease expenses and subtracting ROU depreciation for a "normalized" EBITDA. For general corporates, the standard is:

Adjusted EBITDA = EBITDA + nonrecurring losses - nonrecurring gains ± other adjustments

I don't see specific lease EBITDA adjustments for general corporates in the provided text. So I'll use:

**Adjusted_EBITDA = 4,636,000,000 EUR**

(with the 90M non-recurring net expense added back to reported EBITDA)

Actually, let me recalculate from scratch using the cash flow approach to verify:

From cash flow statement:
Cash Flows From Used In Operating Activities: 2,978,000,000 EUR

Adjustments to reconcile:
- Adjustments For Provisions And Adjustments For Depreciation And Amortisation Expense And Impairment Loss Reversal Of Impairment Loss Recognised In Profit Or Loss: 2,261,000,000 EUR
- Adjustments For Depreciation And Other Adjustments Right Of Use Assets: 424,000,000 EUR
- Adjustments For Losses Gains On Disposal Of Noncurrent Assets: -285,000,000 EUR
- Adjustments For Income Tax Expense: 424,000,000 EUR
- Other Adjustments To Reconcile Profit Loss: -194,000,000 EUR
- Adjustments For Undistributed Profits Of Investments Accounted For Using Equity Method: -92,000,000 EUR
- Adjustments For Dividend Income From Non Controlling Interests: 11,000,000 EUR

Total adjustments = 2,261 + 424 - 285 + 424 - 194 - 92 + 11 = 2,549,000,000 EUR

Profit Loss = 1,131,000,000 EUR

Check: 1,131 + 2,549 = 3,680,000,000 EUR. But operating cash flow is 2,978,000,000 EUR. Difference is working capital changes.

Increase Decrease In Working Capital: 606,000,000 EUR (positive means cash inflow, so source of cash)

Actually: 3,680 - 606 = 3,074? Not matching exactly. Let me check income taxes paid.

Cash Flow After Cost Of Net Debt Interest Expense On Lease Obligations And Income Taxes Paid: 3,324,000,000 EUR
Adjustments For Cost Of Net Debt And Interest Expense On Lease Obligations: 260,000,000 EUR
Income Taxes Paid Classified As Operating Activities: 518,000,000 EUR

So before tax and interest: 3,324 + 260 + 518 = 4,102,000,000? No wait, the 3,324 is after cost of net debt and taxes.

Let me try: Cash Flow After Cost Of Net Debt Interest Expense On Lease Obligations And Income Taxes Paid = Operating cash flow before working capital - interest - taxes? 

Actually, looking at the structure:
Cash Flows From Used In Operating Activities = 2,978,000,000 EUR

This includes:
- Working capital changes: 606,000,000 EUR (positive, cash source)
- Income taxes paid: -518,000,000 EUR (use of cash)
- Interest paid? Not clear if included.

The line "Cash Flow After Cost Of Net Debt Interest Expense On Lease Obligations And Income Taxes Paid" = 3,324,000,000 EUR suggests this is before working capital changes.

So: Operating cash flow before working capital = 3,324,000,000 EUR
Less: Working capital increase (use of cash if positive? Actually positive 606M means source, so add): +606,000,000
Less: Income taxes paid? Wait, 3,324 already includes taxes paid.

Actually 3,324 + 606 = 3,930, but operating cash flow is 2,978. Difference is 952M. Hmm.

Let me try another approach: 3,324 (after interest and taxes) + working capital 606 = 3,930. But we need to subtract something.

Actually, I think "Increase Decrease In Working Capital" of 606M is already reflected in the 2,978M operating cash flow. So:
Operating CF = 2,978 = (some base) + 606 - other items.

This is getting complex. Let me stick with the income statement approach for EBITDA.

From the P&L:
Revenue: 44,322 + 76 = 44,398M
Operating profit (recurring): 1,962M
So operating margin = 4.4%

Adding back depreciation: 2,228 + 446 = 2,674M
EBITDA (recurring basis) = 1,962 + 2,674 = 4,636M

This is consistent. I'll use **Adjusted_EBITDA = 4,636,000,000 EUR**

## Step 3: Estimate FFO

FFO = Adjusted_EBITDA - cash_interest - cash_taxes

Cash interest: From the data, "Cost Of Net Debt" = 198,000,000 EUR. But this includes interest income. Let me look for actual interest paid.

From cash flow: "Interest Paid Classified As Financing Activities" = 260,000,000 EUR
Also: "Adjustments For Cost Of Net Debt And Interest Expense On Lease Obligations" = 260,000,000 EUR

This 260M equals: Interest Expense (231M) + Interest Expense On Lease Liabilities (62M) - Interest Income On Cash And Cash Equivalents (33M) = 231 + 62 - 33 = 260M. Yes!

So cash interest paid = 260,000,000 EUR (this is the actual cash outflow for interest)

Cash taxes: "Income Taxes Paid Classified As Operating Activities" = 518,000,000 EUR

FFO = 4,636,000,000 - 260,000,000 - 518,000,000 = **3,858,000,000 EUR**

Wait - I need to check if S&P uses "cash interest" or "interest expense". The formula says "cash_interest". The cash flow shows 260M as the adjustment for cost of net debt and interest on lease obligations, and also 260M as interest paid in financing activities. So cash interest = 260M.

But let me verify: Is the 260M the right number? The interest expense is 231M, interest on leases is 62M, interest income is 33M. Net = 260M. Cash paid = 260M. This seems correct.

However, S&P sometimes uses a different definition. Let me check if they want interest expense rather than cash paid. The formula explicitly says "cash_interest", so I'll use 260M.

FFO = 4,636,000,000 - 260,000,000 - 518,000,000 = 3,858,000,000 EUR

## Step 4: Estimate Adjusted_Debt

Adjusted_Debt = (reported_debt + leases + pension_deficit + guarantees + hybrid_debt_portion + other_debt_like_items) - eligible_cash

Reported debt:
- Longterm Borrowings: 11,586,000,000 EUR
- Current Borrowings And Current Portion Of Noncurrent Borrowings: 1,361,000,000 EUR
- Current Overdrafts And Short Term Borrowings From Banks: 418,000,000 EUR

Total reported debt = 11,586 + 1,361 + 418 = 13,365,000,000 EUR

Leases:
- Noncurrent Lease Liabilities: 2,107,000,000 EUR
- Current Lease Liabilities: 498,000,000 EUR
Total lease liabilities = 2,605,000,000 EUR

Pension deficit: Not explicitly stated. We have "Other Noncurrent Financial Assets" and various provisions, but no specific pension deficit. Looking at noncurrent provisions of 2,250M and current provisions of 1,832M - these could include pension provisions but we don't have detail. I'll assume 0 for pension deficit unless clearly indicated.

Actually, looking at the equity section, there's no specific pension reserve mentioned. The "Other Comprehensive Income Before Tax Gains Losses On Remeasurements Of Defined Benefit Plans" = 206M, but this is a gain, not a deficit.

For general corporate, if no specific pension deficit is disclosed, we may use 0 or estimate. Given the data, I'll use 0.

Guarantees: Not disclosed in the data. Use 0.

Hybrid debt portion: Not disclosed. Use 0.

Other debt-like items: Could include securitization, derivatives, etc. The "Other Current Financial Liabilities" = 13M, "Hedging Instrument Liabilities" = 4M. These are small. I'll include them? Actually these are typically not debt-like in the same way.

Actually, let me check: "Other Noncurrent Financial Assets" = 584M, "Other Current Financial Assets" = 32M. Not liabilities.

For debt-like items, we might consider:
- Hedging Instrument Liabilities: 4M
- Other Current Financial Liabilities: 13M

These are already quite small. I'll ignore for practical purposes, or include if material. They're 17M total, negligible.

Eligible cash: Cash And Cash Equivalents = 5,736,000,000 EUR

But we need to check if all cash is eligible. S&P typically excludes restricted cash. No indication of restricted cash in the data. However, they sometimes use "available cash" which might be less than total.

Looking at "Cash And Cash Equivalents If Different From Statement Of Financial Position" = 5,318,000,000 EUR. This might be the available cash after adjustments.

Actually, the line says "If Different From Statement Of Financial Position" - this suggests 5,318M is an alternative measure. But 5,736M is the balance sheet figure. For S&P, they typically use the reported cash and equivalents unless there's restricted cash.

However, looking at the net debt calculation: "Net Debt" = 7,440,000,000 EUR.

Let's verify: Total debt (13,365M) + leases (2,605M) - cash (5,736M) = 10,234M. Not equal to 7,440M.

Hmm, maybe net debt is calculated differently. Let me check: 13,365M debt - 5,736M cash = 7,629M. Close to 7,440M but not exact. Difference is 189M.

Or maybe: Longterm borrowings (11,586) + Current borrowings (1,361) + Current overdrafts (418) + Lease liabilities (2,605) - Cash (5,736) - Other current financial assets (32) - Hedging instrument assets (193)? = 11,586+1,361+418+2,605-5,736-32-193 = 10,009. No.

Actually, maybe "Net Debt" as reported by the company includes only certain debt items. Let me try: 11,586 + 1,361 + 418 - 5,736 = 7,629. Still not 7,440.

Or maybe they use a different cash figure: 11,586 + 1,361 + 418 - 5,318 = 8,047. No.

Let me try with leases: 11,586 + 1,361 + 418 + 2,107 + 498 - 5,736 = 10,234. No.

Hmm, 7,440 is close to 7,629. Maybe there's some other adjustment. Or maybe the 7,440 is at a different point in time or uses average balances.

Actually, looking more carefully: "Net Debt" 2023-01-01: 7,440,000,000 EUR. This is year-end 2022.

Let me try: Longterm Borrowings (11,586) + Current Borrowings (1,361) + Current Overdrafts (418) - Cash (5,736) = 7,629. 

Difference from 7,440 is 189M. Could be other financial assets deducted? 193M hedging assets - 4M hedging liabilities = 189M! Yes!

So Net Debt = 11,586 + 1,361 + 418 - 5,736 - 189 = 7,440M? Wait: 11,586+1,361+418 = 13,365. 13,365 - 5,736 - 189 = 7,440. Yes! 189 = 193 - 4.

So the company's net debt includes debt minus cash minus net hedging assets.

For S&P Adjusted Debt, we typically:
- Include all debt (including leases as debt-like)
- Subtract only cash and liquid investments (not hedging assets)

So Adjusted_Debt = Reported debt + Lease liabilities - Cash

= 13,365,000,000 + 2,605,000,000 - 5,736,000,000 = 10,234,000,000 EUR

But wait - S&P might include current portion of long-term debt differently, or include overdrafts differently. Let me check the components again.

Actually, looking at the data more carefully:
- "Current Borrowings And Current Portion Of Noncurrent Borrowings" = 1,361M
- "Current Overdrafts And Short Term Borrowings From Banks" = 418M

These might overlap or be separate. The total debt should include both.

For S&P methodology, they typically add:
- All interest-bearing debt
- Lease liabilities (operating lease equivalent)
- Less: Cash and cash equivalents

So: 13,365 + 2,605 - 5,736 = 10,234M

But let me also consider if we should use the "Cash And Cash Equivalents If Different From Statement Of Financial Position" of 5,318M. This might be more available cash. If we use that: 13,365 + 2,605 - 5,318 = 10,652M.

However, the standard is to use balance sheet cash unless there's clear restriction. I'll use 5,736M.

Actually, I want to double-check the S&P general corporate approach. They typically use:
- Gross debt: All short-term and long-term borrowings, plus finance leases, plus other debt-like items
- Less: Cash and marketable securities

For IFRS 16, all leases are finance leases, so we include all lease liabilities.

Adjusted_Debt = 13,365 + 2,605 - 5,736 = **10,234,000,000 EUR**

## Step 5: Calculate FFO / Adjusted_Debt

FFO / Adjusted_Debt = 3,858,000,000 / 10,234,000,000 = 0.37698...

Let me recalculate more precisely:
3,858 / 10,234 = 0.376978698...

Rounded to four decimal places: **0.3770**

Wait - let me double-check all my calculations.

### Rechecking EBITDA:

Revenue: 44,322 + 76 = 44,398M

Operating expenses (recurring basis):
- Raw Materials: 19,372
- Employee: 10,381
- Services: 10,572
- Tax other than income: 639
- Depreciation & Amortization: 2,228
- Depreciation ROU: 446
- Impairment/provisions: 172
- Inventory change: -61
- Other expense recurring: 1,252
- Other income recurring: -2,565 (negative as it's income)

Total expenses = 19,372 + 10,381 + 10,572 + 639 + 2,228 + 446 + 172 + (-61) + 1,252 - 2,565 = 42,436M

Revenue - expenses = 44,398 - 42,436 = 1,962M = Profit Loss From Operating Activities Recurring. ✓

EBITDA = Operating profit recurring + D&A + ROU depreciation = 1,962 + 2,228 + 446 = 4,636M

Or: EBITDA = Revenue - (expenses excluding D&A and ROU depreciation)
= 44,398 - (19,372 + 10,381 + 10,572 + 639 + 172 + (-61) + 1,252 - 2,565)
= 44,398 - 39,762 = 4,636M ✓

Non-recurring adjustment: 183M expense - 93M income = 90M net expense
Add back to get to "normalized" = 4,636M (already using recurring basis)

Actually wait - my EBITDA of 4,636M is already on a recurring basis. If I started from reported operating profit of 1,872M, I'd add 90M to get to recurring, then add D&A.

Reported operating profit: 1,872M
Add non-recurring net expense: 90M
Recurring operating profit: 1,962M
Add D&A: 2,674M
EBITDA: 4,636M

Yes, consistent.

### Rechecking FFO:

Adjusted_EBITDA: 4,636M
Cash interest: 260M (from cash flow statement - interest paid)
Cash taxes: 518M (from cash flow statement - taxes paid)

FFO = 4,636 - 260 - 518 = 3,858M

But wait - is the "Cost Of Net Debt" of 198M the right interest measure? Let me check:
- Interest Expense: 231M
- Interest Income: 33M
- Net: 198M

But cash interest paid is 260M, which includes lease interest of 62M.
- Interest Expense: 231M
- Interest on Lease Liabilities: 62M
- Less: Interest Income: 33M
- Total cost of net debt and lease interest: 260M

And 260M is also the cash paid. So yes, cash interest = 260M.

However, for FFO, S&P uses "cash interest" which typically means actual interest paid, not the P&L expense. The 260M appears to be the cash outflow.

But actually, looking more carefully: "Adjustments For Cost Of Net Debt And Interest Expense On Lease Obligations" = 260M. This is added back in the cash flow reconciliation (from profit to operating cash flow before working capital). And "Interest Paid Classified As Financing Activities" = 260M.

So the company paid 260M in interest. This is the cash interest.

FFO = 4,636 - 260 - 518 = 3,858M

### Rechecking Adjusted Debt:

Reported debt:
- Longterm Borrowings: 11,586M
- Current Borrowings And Current Portion Of Noncurrent Borrowings: 1,361M  
- Current Overdrafts And Short Term Borrowings From Banks: 418M
Total: 13,365M

Lease liabilities:
- Noncurrent: 2,107M
- Current: 498M
Total: 2,605M

Cash: 5,736M

Adjusted Debt = 13,365 + 2,605 - 5,736 = 10,234M

### Final calculation:

FFO / Adjusted_Debt = 3,858 / 10,234 = 0.3769787...

Rounded to four decimal places: 0.3770

Actually, let me verify the rounding: 0.3769787... the fifth decimal is 7, so round up: 0.3770.

Wait, let me be more careful: 3,858 / 10,234 = ?
3,858 ÷ 10,234 = 0.376978698846...

To four decimal places: 0.3770 (since 8th digit is 7, and 9th is 8, we round the 6 up to 7, making 0.3770? No wait:

0.376978... 
Position 1: 3
Position 2: 7
Position 3: 6
Position 4: 9
Position 5: 7

So it's 0.3769 with the next digit being 7, so round up to 0.3770.

Actually 0.3769 + 0.0001 = 0.3770. Yes.

But wait - I want to double check if I should use the "Cash And Cash Equivalents If Different From Statement Of Financial Position" figure. The company reports 5,736M on balance sheet but 5,318M as "if different". This 5,318M might exclude restricted cash or include other adjustments.

If I use 5,318M:
Adjusted Debt = 13,365 + 2,605 - 5,318 = 10,652M
FFO/Debt = 3,858 / 10,652 = 0.3622

This is quite different. Which is correct?

Looking at the label: "Cash And Cash Equivalents If Different From Statement Of Financial Position" - this suggests it's an alternative measure, perhaps used in the cash flow statement. The cash flow statement starting point uses 5,318M for 2023 and 6,150M for 2022, while balance sheet shows 5,736M and 6,501M.

Actually, the cash flow statement shows:
"Cash And Cash Equivalents If Different From Statement Of Financial Position" 2022-01-01: 6,150M
But balance sheet "Cash And Cash Equivalents" 2022-01-01: 6,501M

And for 2023-01-01: 5,318M vs 5,736M.

The difference is 351M for 2022 and 418M for 2023. These differences might be bank overdrafts or other items netted against cash in the cash flow statement.

For S&P purposes, we typically use the balance sheet cash and equivalents unless there's clear restriction. The "if different" note suggests this is a cash flow presentation issue, not a restricted cash issue.

I'll stick with 5,736M.

However, I want to reconsider the lease treatment. Under S&P's general corporate methodology with IFRS 16:

Some S&P approaches treat IFRS 16 leases by:
- Including lease liabilities in debt
- But NOT adjusting EBITDA (since EBITDA already excludes lease depreciation and interest, and the "operating lease expense" is already gone)

Actually, with IFRS 16, the old "operating lease expense" is replaced by:
- Depreciation of ROU assets (in operating expenses, but added back for EBITDA)
- Interest on lease liabilities (below operating profit, so excluded from EBITDA)

So EBITDA under IFRS 16 is HIGHER than under old IAS 17 because there's no operating lease expense deduction.

S&P's standard approach is to calculate a "hybrid" EBITDA that adds back the full lease expense as if operating leases still existed. This is done by:
- Taking reported EBITDA
- Adding back interest on lease liabilities
- Adding back depreciation of ROU assets  
- Subtracting an imputed "operating lease expense" (typically based on the lease payment)

Actually, I need to check this more carefully. The provided methodology doesn't specify this for general corporates, but for utilities it mentions purchased power and seasonal working capital adjustments.

For general corporates, S&P's standard approach since IFRS 16 has been to use reported EBITDA (which benefits from IFRS 16) but include lease liabilities in debt. This creates a mismatch that reduces the ratio, which is intentional - it makes leverage look higher.

However, some S&P analyses do adjust EBITDA to a "pre-IFRS 16" basis by adding back the lease depreciation and interest, then subtracting an operating lease expense.

Given the provided methodology says "modifying it as required by the industry methodology identified in Step 1", and since general corporate is the default with no specific modifications mentioned, I'll use the standard formula as given:

Adjusted_EBITDA = EBITDA (reported or reconstructed) + adjustment_leases (if any) + nonrecurring_losses - nonrecurring_gains ± pension_adjustments ± joint_venture_proportional_EBITDA ± other_normalization_adjustments

For "adjustment_leases (if any)" - this suggests we add back lease-related adjustments if required. But with IFRS 16, there's no operating lease expense to add back to EBITDA because it's already not deducted in EBITDA (the depreciation is added back, and interest is below the line).

Actually, let me think again. Under IFRS 16:
- Operating profit includes depreciation of ROU assets
- EBITDA adds back this depreciation
- So EBITDA is higher than under IAS 17 by the amount of old operating lease expense minus new depreciation

Wait, that's not right either. Let me think step by step:

Under IAS 17 (old):
- Operating lease expense: e.g., 500M
- This reduced operating profit and EBITDA

Under IFRS 16:
- Depreciation of ROU: 446M (in operating expenses)
- Interest on leases: 62M (below operating profit)
- Total: 508M vs old 500M

For EBITDA under IFRS 16:
- Start with operating profit (after depreciation)
- Add back depreciation of ROU: 446M
- EBITDA includes the benefit of not having 500M operating lease expense, but has 62M interest below the line

So EBITDA under IFRS 16 = EBITDA under IAS 17 + (old lease expense - new depreciation) = higher by 500 - 446 = 54M, plus interest is 62M lower in the EBITDA-to-FFO calculation.

Actually for FFO = EBITDA - cash interest - cash taxes:
- Under IFRS 16: higher EBITDA, but cash interest includes lease interest
- Under IAS 17: lower EBITDA, but no lease interest in cash interest

So they roughly offset if lease expense ≈ lease depreciation + lease interest.

Given this complexity, and that the formula says "adjustment_leases (if any)", I'll check if there's an explicit lease adjustment needed. For general corporates with IFRS 16, S&P sometimes does NOT adjust EBITDA, precisely because the higher EBITDA is offset by higher debt and higher interest.

So my original calculation stands: **Adjusted_EBITDA = 4,636M**

But let me reconsider if I should add back the ROU depreciation to get a "true" pre-IFRS 16 EBITDA. Actually no - reported EBITDA already includes the add-back of ROU depreciation. The issue is whether we should subtract an imputed operating lease expense.

Given the formula provided says "+ adjustment_leases (if any)", this suggests adding back lease expense (i.e., making EBITDA higher). But with IFRS 16, there's no lease expense in operating profit to add back. The depreciation is already added back in reported EBITDA.

I think the standard S&P approach for general corporates post-IFRS 16 is:
- Use reported EBITDA (which is higher due to IFRS 16)
- Include lease liabilities in debt
- This is intentionally conservative

So I'll proceed with 4,636M.

### Final verification of numbers:

FFO = 3,858M
Adjusted Debt = 10,234M
Ratio = 0.3770

Let me also consider if I should use the "Net Debt" figure of 7,440M as a check. If S&P Adjusted Debt were 7,440M, the ratio would be 3,858/7,440 = 0.5185. But this net debt excludes lease liabilities from debt, which is not S&P's approach.

Actually, wait - let me re-read the net debt calculation. The company's net debt of 7,440M = total debt - cash - hedging. If they include leases in "total debt" for net debt purposes, then:
13,365 debt + 2,605 leases - 5,736 cash - 189 hedging = 10,045M? No, 13,365 + 2,605 = 15,970. 15,970 - 5,736 - 189 = 10,045. Not 7,440.

So the company's "Net Debt" of 7,440M must exclude leases. Let me check: 13,365 - 5,736 - 189 = 7,440? 13,365 - 5,736 = 7,629. 7,629 - 189 = 7,440. Yes!

So the company's net debt = reported debt (excluding leases) - cash - net hedging assets.

For S&P, we add leases to debt. So Adjusted Debt should be higher than the company's net debt.

Adjusted Debt = Company Net Debt + Lease Liabilities + Hedging assets (if we deducted) - any other differences
= 7,440 + 2,605 + 189? No, the 189 was already deducted to get to 7,440.

Actually: Company Net Debt = 13,365 - 5,736 - 189 = 7,440
S&P Adjusted Debt = 13,365 + 2,605 - 5,736 = 10,234

Difference = 10,234 - 7,440 = 2,794 = 2,605 leases + 189 hedging

So yes, S&P Adjusted Debt is higher because it includes leases and doesn't net hedging.

### Final Answer:

FFO / Adjusted_Debt = 3,858 / 10,234 = 0.3770
