RIO DE JANEIRO, Feb 26 (Reuters) - Brazil's Petrobras

posted a net loss of 17 billion reais ($2.8 billion)

in its fourth quarter due to non-recurring events, but aims to

distribute dividends, the firm said on Wednesday.

The company said on a separate filing to the one about

its results that it's set to distribute 9.1 billion reais in

ordinary dividends.

The net loss, which compares with a 31 billion real net

profit a year earlier, was mainly affected by exchange rate

variation on debts between the state-run oil firm and its

subsidiaries abroad, said the firm.

According to Petrobras, the financial transactions did

not impact its cash flow, and excluding them, the firm would

have posted a net profit of 17.7 billion reais in the quarter,

still a 53% drop year-on-year.

The firm reported a 10% decrease in net revenue at 121.3

billion reais, below estimates from analysts polled by LSEG of

127.8 billion reais.

Petrobras' adjusted earnings before interest,

depreciation and amortization (EBITDA) stood at 41 billion

reais, way below analysts' estimates of 63.6 billion reais, and

a 39% decline year-on-year.
