Net financial debt (dette financière nette — DFN) is the difference between all interest-bearing financial obligations (bank debt, bonds, finance leases, shareholder loans) and available net cash (cash, bank balances, short-term liquid investments). It is the central bridge between enterprise value and equity value in M&A transactions. Its precise definition — which items are included or excluded — is one of the most negotiated points in SPAs, particularly for IFRS 16 leases, pension deficits, earn-out liabilities and off-balance-sheet contingencies.

‍

Example: a Swiss company is acquired at CHF 22.0 million enterprise value. Net financial debt at closing: bank debt CHF 6.5 million + IFRS 16 leases CHF 1.2 million + shareholder loans CHF 800,000 - cash CHF 1.8 million = CHF 6.7 million. Equity value paid to shareholders = CHF 22.0 - 6.7 = CHF 15.3 million — the actual proceeds received by the sellers.
