The Troy, Mich., company, which filed for bankruptcy protection in 2005, said in a filing with the Securities and Exchange Commission that its net loss for January through November amounted to $2.78 billion.

Delphi recorded about $1.15 billion in net sales for last month.

Delphi, the country's biggest maker of auto parts, has been in Chapter 11 proceedings since October 2005 and aims to exit bankruptcy before the end of March. The company was spun off in 1999 from General Motors Corp., which has borne a large chunk of Delphi's restructuring costs.
