Most acquisitions and mergers are completed without any problems, but when disputes arise afterwards, significant assets are often at stake and the cases can be complex. Disputes may, for example, concern price adjustments, breaches of warranties, hidden defects and deficiencies, or other disagreements relating to the agreement.
Successfully handling such disputes requires commercial acumen, in-depth knowledge of the transaction’s background, and a sound understanding of how companies are valued and agreements structured. When W&I (Warranty & Indemnity) insurance has also been taken out, further legal and practical issues come into play.
