Google and EU regulators are close to settling a three-year antitrust investigation into the companys suspected anti-competitive behaviour after it offered improved concessions to allay competition concerns, two sources said on Thursday. A settlement under the European Commissions antitrust rules means Google will escape a possible fine of as much as $5 billion. The worlds biggest Internet search engine and the European Commission is close to a deal and a decision is expected in the next few days or in a couple of weeks at the latest, a senior European Union official said. The official said Googles latest proposal, its third after EU Competition Commissioner Joaquin Almunia rejected an earlier offer as unacceptable, was much better.
