Brazilian state-run oil company Petrobras said on Jan. 4 its board of directors had approved the early departure of CEO Caio Paes de Andrade, which will take effect immediately.

Reuters had first reported on Jan. 3, citing sources, that Andrade had informed the board of directors of his resignation, ahead of the end of his term in April.

Petrobras' production head, Joao Henrique Rittershaussen, has been named as interim CEO, it said in a securities filing, adding Andrade had also resigned from the board of directors.

Senator Jean Paul Prates, who was appointed by President Luiz Inacio Lula da Silva to head the company, is expected to take over from the interim CEO, although he will require approval from internal Petrobras committees.

Prates has advocated for higher Petrobras investments in renewables and refining. He has also said he plans to adjust Petrobras' fuel pricing policy that pegs local fuel to international prices and foreign exchange rates.

Preferred shares in Petrobras traded near flat on Jan. 4 following the news, still down roughly 9% this year after Brazilian financial markets tanked on fears regarding Lula's economic policy.
