The change at the top of the company, which entered bankruptcy protection in May, is expected to take place either at the end of this year or when Light completes its financial reorganization, whichever comes first, according to the report.

Light's board of directors also chose Vinicius Roriz, who currently is director of people and management, as the firm's next chief operating officer, said the report.
