UPDATE 4-Usiminas shares jump as Brazil decision forces tender offer
(Updates with regulator's statement on price of offer)
RIO DE JANEIRO, April 15 (Reuters) - Common shares in Brazil's Usiminas jumped over 16 percent on Wednesday after securities industry regulator CVM demanded its two top shareholders extend a tender offer for the rest of the steelmaker's common shares.
The decision is the latest twist in a struggle for control between the shareholders Luxembourg-based Ternium SA and Japan's Nippon Steel & Sumitomo Metal Corp.
Ternium said on Wednesday it would appeal the CVM decision, while Nippon said it needed to fully understand the details before making a decision.
Regulator CVM on Wednesday told Reuters that the offer price should be calculated based on a "fair value" criteria. It said that fair price should be established in an appraisal report.
The two control Usinas Siderúrgicas de Minas Gerais SA, as the company is formally known, through a shareholder accord but have been at loggerheads for six months over the departure of the steelmaker's former chief executive officer, leading to a number of court cases and appeals to the regulator.
The CVM decision relates to last October, when Ternium increased its stake by buying 616.7 million reais ($200 million) worth of shares from the workers' pension fund of state-run Banco do Brasil SA, known as Previ. At the time, Ternium stated the deal would not trigger a tender offer to other minority shareholders.
The decision by the CVM, which was asked to review the deal by Nippon Steel, overturns that and says the offer must be extended by both Ternium and Nippon Steel, according to the Usiminas statement late Tuesday.
