German logistics billionaire Klaus-Michael Kuehne said that he was examining the submission of a public takeover bid for Hamburger Hafen und Logistik Aktiengesellschaft (HHLA) (XTRA:HHFA), the main operator of Hamburg port, but would prefer an agreement with the city of Hamburg on its privatisation. "We are examining the submission of a public takeover bid, but would prefer an agreement with the city of Hamburg on privatisation - be it in the direction of Kuehne Holding, or in the direction of Hapag-Lloyd Aktiengesellschaft (XTRA:HLAG)," in which he owns a 30% stake, Kuehne told Reuters in an emailed statement.
