Contributions and mergers auditing

Contributions and mergers auditing

Contributions and mergers auditing plays an essential role in protecting shareholders’ interests in the context of transactions carried out in securities.
We assist you with transactions relating to contributions, merger and spin-off by appraising contributions and mergers. We also assess the value of the special advantages created by these transactions or by the issue of preference shares.

Our partners are frequently appointed by parties directly, or by the Commercial or Regional courts, to issue an opinion on the fairness of a merger or spin-off or to assess the value of a contribution or, where applicable, of special advantages.

Following the introduction of the Warsmann law of 22 March 2012, our partners, or the firm as such, represented by one of its partner, can be appointed as contributions or mergers auditor by unanimous decision of the shareholders or partners.

We have the skills required to handle both public and private-company transactions of all sizes, across a wide range of business sectors.

Our team has also been involved in business combinations resulting in the creation of major groups in various business sectors.
