RIO DE JANEIRO (Reuters) - Brazil's largest fixed line carrier Oi SA (SA:OIBR4), which is currently in bankruptcy protection, said on Monday that Chief Financial Officer Flavio Nicolay Guimarães resigned, without giving a reason for his departure.
Guimarães will be replaced by Ricardo Malavazi Martins, Oi said in a securities filing. As part of the move, Martins stepped down from his position on the board of Oi, the company said.
Martins previously worked at Brazilian bank Bradesco (SA:BBDC4) between 1990 and 2003 and as CFO for Petros, the pension fund for state-run oil company Petrobras (SA:PETR4), for six years.
