SAO PAULO, June 9 (Reuters) - Controlling shareholders are not in negotiations about breaking up Brazil's Usiminas , the chief executive of the troubled steelmaker said on Thursday, in the midst of an ongoing boardroom battle for control.
CEO Sergio Leite, speaking on the sidelines of a steel event in Sao Paulo, ruled out filing for bankruptcy protection and said the company was up to date with debt payments.
