Guarantee

A guarantee is a commitment by which a third party (the guarantor) undertakes to fulfil the obligations of a primary debtor if that debtor defaults. In corporate finance and financial structuring, guarantees take multiple forms: bank guarantees (payment on demand), personal director guarantees, parent company guarantees, and asset and liability warranties in M&A. In financial due diligence, guarantees given by the target on behalf of third parties (subsidiaries, affiliates, business partners) constitute off-balance-sheet contingent liabilities that must be identified, quantified and integrated into the net debt definition to ensure an accurate equity value bridge.

‍

Contractual guarantees in M&A refer specifically to the representations, warranties and indemnities given by the seller in the SPA: the seller's commitment that specific statements about the company are true and that the buyer will be indemnified for any losses arising from their inaccuracy. Key negotiated parameters include the basket (minimum threshold before claims can be made), the cap (maximum aggregate liability), the survival period and the disclosure letter carve-outs; their scope and calibration determine the buyer's post-closing protection.

Example: due diligence on a Swiss holding company identifies CHF 3.5 million of guarantees given in favour of foreign subsidiaries. These unprovisioned liabilities are treated as debt-like items in the adjusted net debt, a 40% call probability assumption reducing the equity value by CHF 1.4 million versus the CHF 22.0 million unadjusted enterprise value. On the contractual side, in a CHF 20.0 million acquisition, an SPA warranty package with a CHF 100,000 basket (0.5%), a 25% price cap (CHF 5.0 million) and a 2-year general warranty period (5 years for tax warranties) yields, on a CHF 350,000 post-closing environmental liability, a net recovery of CHF 250,000 after the basket, within the cap; warranty scope and the seller's knowledge at signing determine enforceability.
