Citigroup, New York, said it used $25.7 billion of Troubled Asset Relief Program (TARP) funds for its residential mortgage activities in the fourth quarter 2008.

That is by far the biggest chunk of the $36.5 billion of TARP money it spent in the period. The company said it made $75 billion in new loans of all types during the fourth quarter.

The report also covered Citi's activities with troubled residential mortgage borrowers. The company said it has worked with approximately 440,000 homeowners whose mortgages totaled $43 billion since the start of the housing crisis in an effort to prevent foreclosure.

In 2008, Citi said it kept approximately four out of five distressed borrowers whose loans it serviced in their homes.

Citi said it is adopting the streamlined model for post-delinquency modification programs developed by the Federal Deposit Insurance Corp.

In addition, through the Citi Homeowner Assistance Program, it is reaching out to those who may be experiencing some form of economic distress although they are current on their mortgage payments.
