Freddie Mac forced its seller/servicers to buy back $951 million of bad mortgages during the second quarter, a 21% increase from the first quarter.
Fannie Mae also saw its outstanding buyback requests continue to increase in the second half of 2009 - but the GSE, unlike Freddie, does not disclose the dollar amount in its securities filings.
Lenders that sell loans to Freddie and Fannie are required to make "representations and warranties" that the loans comply with the GSEs' underwriting requirements. If the loans do not perform as expected and underwriting deficiencies are flagged, the lender is obligated to buy back the loans.
The GSEs are concerned that their credit losses will grow if lenders cannot muster the financial wherewithal to meet their buyback obligations.
Freddie recently noted that it terminated Taylor Bean & Whitaker's status as a seller/servicer on Aug. 4.
"We are in the process of determining our total exposure to TBW in the event it cannot perform its contractual obligations to us. The amount of our losses in such an event could be significant," Freddie said in its second-quarter securities filing.
The Federal Housing Administration recently suspended TBW as a lender.
