Federal Housing Finance Agency. OIG Finds Room for Improvement. The FHFA recognizes how important it is to oversee Fannie Maes and Freddie Macs default-related legal services, but it needs to improve its capacity to identify new and emerging areas of risk, according to a new report released by the agencys Office of Inspector General. Additionally, FHFA does not have a continuous supervision plan or detailed examination guidance to govern its oversight of Fannies Retained Attorney Network, and it had not accomplished any targeted examinations of the RAN until it initiated a special review in late 2010, which has not yet been published, the OIG said. Moreover, FHFA also has not developed formal policies to address poor performance by law firms that have relationships either directly through contract or through its loan servicers with both enterprises to ensure that information is shared.
