Centrais Eletricas do Para SA, a Brazilian utility know as Celpa that was acquired this month by Equatorial Energia SA, filed for Chapter 15 bankruptcy protection in New York, Bloomberg reported. The company, based in Belem, Brazil, listed both debt and assets of more than $1 billion in documents filed today in U.S. Bankruptcy Court in Manhattan. Chapter 15 protects foreign companies from U.S. lawsuits and creditor claims while a company reorganizes abroad. Celpa is asking the U.S. court to recognize the proceeding pending before the Thirteenth Civil Court of Belem, State of Para, as a “foreign main proceeding,” according to court papers.
