Canada's Gardaworld extends offer for UK's G4S

The offer will remain open for acceptance until Nov. 28, GardaWorld said in a statement."We are extending our offer for G4S because, despite its past problems and uncertain future, we believe we can turn the business around," GardaWorld's Chief Executive Stephan Cretier said.G4S, one of the world's largest private security firms, had rejected GardaWorld's 190 pence per share offer valuing the company at 2.97 billion pounds, calling it "unattractive and opportunistic".
