KUALA LUMPUR: Petroliam Nasional Bhd, Malaysia's state oil company more commonly know as Petronas, reported a quarterly net loss on Friday versus a profit in the year-ago quarter, hit by a drop in oil prices and an impairment charge.

The state-owned firm posted a net loss of 7.3 billion ringgit ($2.03 billion) in October-December 2014 compared to a profit of 12.8 billion ringgit in the same period in 2013, Petronas said in a statement.

Unlisted Petronas is Malaysia's only Fortune 500 Company and accounts for most of the government's oil and gas revenue.
