The choice of the form of acquisition should stand at the beginning of structuring.
Whether a share deal or an asset deal is the better choice depends on the target company, on the liability situation and on tax considerations. Clarify early which contracts, employees and assets are to pass and which risks you do not want to take on. This decision shapes the entire purchase contract.
A structured weighing of both routes before the start of the negotiation saves later corrections. The form of acquisition can be changed afterwards only with difficulty.
