Nestle has said that it has received several offers for Perrier and it has not ruled out a sale. The company's chief executive has warned that a sale is still an option if trade unions continue to block Nestle's efforts to improve productivity.

Speaking at a press conference following the company's 2004 results, Peter Braebeck said: "We are willing to continue investing in Perrier … but there will be nothing unless there is backing from unions for increasing productivity. The option of selling Perrier is still on the table."

Nestle's CEO, Frits van Dijk, said that Nestle has received offers for the beleaguered water unit, but has not held discussions yet. "This file (of potential buyers) is already being studied" in case there is no breakthrough with the unions, Van Dijk said.
