Recently, the FHFA Office of the Inspector General (OIG) concluded that the FHFA can further mitigate the risks posed by Fannie Mae’s and Freddie Mac’s reliance on third-party mortgage loan sellers and servicers (counterparties). The OIG recommended that the FHFA direct the two GSEs to assess a risk-based approach as to whether the counterparties should obtain independent, third-party attestations of their compliance with origination and servicing requirements, which would complement but not replace Fannie Mae’s and Freddie Mac’s own onsite reviews and other performance monitoring controls. The purpose of the recommendation was to increase assurance that the $4.8 trillion in GSE-owned and -guaranteed mortgages are appropriately originated and serviced. The recommendation came at the heels of an OIG audit of FHFA’s oversight over how the GSEs ensure that third party loan sellers and servicers comply with the GSEs’ requirements. The OIG’s recommendation was based on the finding that the GSEs currently rely on the counterparties’ self-representations of their compliance, and only a portion of loans purchased are subject to detailed quality reviews. Per the OIG’s recommendation, the attestations can be implemented in a manner that considers cost versus benefit based on a given counterparty’s size, complexity, performance, and other risk factors. The FHFA did not agree with the OIG recommendation, and the OIG is requesting that FHFA reconsider its disagreement with the recommendation.
