Fiat SpA chairman Umberto Agnelli said on Thursday that the ailing Italian industrial conglomerate will present an "operating plan" detailing the management's intentions by the end of June, Dow Jones reported. The plan would be "quite complete and respond to the needs of maintaining maximum employment levels, while also boosting efficiency to boost Fiat's results," Dow Jones cited Agnelli telling a shareholder at the annual meeting of Istituto Finanziario Industriale SpA (IFI), his family-run holding company.
