The shareholder pool, comprised of descendants of Roche founder Fritz Hoffman-La Roche, said the pool now counted nine fifth-generation and six fourth-generation family members.

"We can thus provide the organisation with the surety that our family, as in the past 120 years, will continue to commit to the stability of Roche's shareholding in the coming decades," Andre Hoffmann, speaker for the family shareholder pool and Roche vice-chairman, said in a statement.
