Facebook Inc (NASDAQ:FB) is in the process of acquiring WhatsApp for $19 billion. The acquisition has been approved by Federal Trade Commission in the U.S., but it still has to be approved by national regulators in European countries.
This is why Facebook had asked regulators at the European Commission to review the deal. It is rare for a company to seek reviews on its own.
Facebook dealt with investigations in Europe several times in regards to privacy. For example, Facebook took some heat for its plans to use facial recognition in Europe.
If Facebook can get approval from the European Commission level from the office of competition commissioner Joachin Almunia, this could potentially supercede any other local decisions.
