New life-of-loan representation and warranty- exclusion guidelines issued by the GSEs in November, appeared to have little impact on banks’ lending policies so far, according to a recent Federal Reserve Board survey.The rep-and-warrant changes were intended to reduce uncertainty and increase transparency in addressing lenders’ concerns about when they might be asked to repurchase a loan. The concerns were based on repurchase risk and other market factors that can cause an increase in credit overlays. “Addressing these concerns by providing tighter definitions and clarity should encourage sellers to serve a broader range of qualified borrowers,” said Dave Lowman, Freddie’s executive vice president of single -family business, when the changes were announced in November.
