Valuing private banks for M&A transactions is a complex process, and not one that is unanimously agreed upon. Sebastian Dovey, head of consulting for Scorpio Partnership, thinks it is not enough to look merely at assets under management when putting a price on private banks. "Looking at AUM and the level of wealth per client is not a telling sign of the company's value. You could end up with wealthy clients who are all very old, and want their money to stay static." In this case, the buyer may have overestimated the transaction-based fees that should be achieved from the acquisition.
