Restructuring Italian lender UniCredit continues to draw bidders for its Pioneer Global Asset Management unit despite potential market upheaval from Italy's looming constitutional referendum. The latest suitor to emerge is Poste Italiane, the postal service company, which announced on Thursday that it will make a bid with asset manager Anima Holding and state-backed lender Cassa dei depositi e prestiti. Poste Italiane already has its own asset manager, BancoPosta Fondi, and a 10.3% stake in Anima. But it said Thursday it is turning the manager over to Anima in return for a bigger equity stake of up to 24.9%. The BancoPosta and Anima duo will have assets of around €147 billion ($159.9 billion), while Pioneer has close to €249 billion of assets under management. UniCredit confirmed Friday it has received offers for Pioneer but did not provide details.
