France's Suez, the top water provider in Spain, has temporarily moved the legal registration of its offices in Catalonia to Madrid because of legal uncertainty related to Catalonia's independence movement.

"We have temporarily moved the registered office of Agbar, which is the (Suez) holding company in Catalonia, to Madrid in order to protect the legal certainty of investors, because what we see now in Catalonia is uncertainty," Chief Financial Officer Christophe Cros said on an earnings call.
