DIAMOND magnate Nicky Oppenheimer has no plans to raise any higher the buy-out bid for De Beers. “This is a take-it-or-leave it offer,” De Beers chairman Nicky Oppenheimer has told the Johannesburg newspaper Business Day. Oppenheimer is driving the move by the bidding consortium, DB Investments, to turn De Beers into a private company run by the Oppenheimer family. DB Investments announced a new offer — of two dollars more per share — on April 26, bringing the value of the proposed deal to $18,6-billion. The initial offer was worth $17,6-billion dollars, and was rejected by asset managers in both the UK and US as under-valuing the world’s leading diamond company. The newspaper said: “A group of shareholders mandated brokers Barnard Jacobs Mellet last week to take a closer look at unbundling (De Beers’ 35-percent stake in Anglo) which, if the possibility existed, could mean that those shareholders would vote against the proposal presented by DB Investments.” Oppenheimer warned that such a move, if allowed, would be a protracted process. He questioned whether the Reserve Bank would allow a full unbundling, given that the “deal on the table would bring $3,5-billion.”
