Brazil's state-owned energy giant Petrobras sold 8.5 billion U.S. dollars' worth of bonds in an overseas sale to fund its investment plan, local media reported on Monday. The bonds, issued by the company's subsidiary Petrobras Global Finance, include four categories with maturities ranging from three to 30 years, according to O Globo daily. The money raised this time will help finance Petrobras' new investment plan. This was Petrobras' second issuance of global bonds this year, with the first in January when the company raised five billion U.S. dollars to fund its business management plan.
