Noble has been sounded out by rival trading companies about buying parts of its Americas-focused oil unit but has so far resisted entering into discussions, the FT reported. It did not name any potential buyers.

Noble had no immediate comment when contacted by Reuters.

A sale of the entire business or part of it would help raise much needed capital at Noble, which has struggled in recent years against a downturn in commodity markets and questions about its accounts by Iceberg Research in 2015. Noble has stood by its accounts.

Last month, Reuters reported that Noble was negotiating with banks to roll over a $2 billion credit facility, secured on its inventories and working capital. The facility is due to be rolled over by the end of June.

Hong Kong based-Noble is a major participant in the global physical oil market, trading large physical volumes including crude and refined products. It also has blending and wholesale capabilities in North America and the Caribbean, as well as storage capacity globally, according to the company's website.

Noble shares were trading 3.4 percent higher on Monday. The stock has fallen more than 80 percent so far this year.
