(Telecompaper) Telenor Group said it is to divest its entire 33 percent stake in VimpelCom and fully focus on creating value in its core operations. Svein Aaser, chairman of Telenor's board of directors said its minority stake and lack of ability to fully control Vimpelcom had been challenging. As a result of today's announcement, Telenor will not convert its VimpelCom preference shares into common shares.
