(Telecompaper) Telecom Italia is preparing an offer of as much as EUR 7 billion to outbid Telefonica for Vivendi's Brazilian broadband unit GVT, people with knowledge of the plan told Bloomberg. Vivendi would get a 20 percent stake in Telecom Italia and a stake in the entity that combines the two companies' Brazilian units. Telefonica offered EUR 6.7 billion for GVT earlier this month. The Brazilian newspaper Folha de Sao Paulo reported separately that Telecom Italia was set to make an all-stock bid for GVT valued at as much as EUR 7 billion.
