Vodafone plans to double its cost-savings program to £2 billion. The UK group said its current cost-cutting program is running ahead of schedule and the additional cuts will come by 2012. "There's a problem with the margins," Michael Kovacocy from Daiwa Institute of Research Europe, said as to why the Vodafone's shares are down.

Yahoo is done with its cost-cutting program and is now hiring, Chief Executive Carol Bartz told CNBC Tuesday. "We're not in cost-cutting mode… we're actually hiring. We're expanding as a company," Bartz said.
