US mortgage agency Freddie Mac has reported a 2008 net loss of $US50.1 billion, nearly half of which occurred in the fourth quarter.
Freddie Mac said on Wednesday it had a fourth quarter net loss of $US23.9 billion, down slightly from a $US25.3 billion loss in the third quarter.
Losses in the final quarter were mainly driven by writedowns and increased credit-related expenses.
Freddie Mac was taken over by the federal government in September to prevent its collapse.
The company said its government-appointed conservator has asked the US Treasury for an additional $US30.8 billion in funding as part of its bailout.
