Over roughly two years, Fannie Mae and Freddie Mac have spent about $65 million on the common securitization platform project, but without employing a timeline on the massive undertaking or a total cost estimate, according to a new report from the Inspector General of the Federal Housing Finance Agency. In its report, released last week, the IG notes that the regulator/conservator of the GSEs has yet to fully employ these “two basic project management tools,” which it deems critical to the project’s success.Although some progress has been made in developing the CSP, the project faces “considerable challenges that could undermine the project.”
