Vkontakte was estimated at $2.2 billion in a recent stake buyout by UCP, says Forbes.

      Co-founders of the ‘Russian Facebook’, Lev Leviev and Vyacheslav Mirilashvili, sold 48 percent of the social network to the United Capital Partners foundation.

      The deal was closed on April 2, but the news emerged only two weeks later.

      The other stakeholders, Russia’s richest man Alisher Usmanov and CEO Pavel Durov complained their preferential acquisition rights, granted by the charter, were violated.

      UCP responded by saying they purchases the Cypriot companies who owned the shares.
