Here is how it works
FHFA says - Cong has to act. TSY has to decide on agreements
TSY says -- Cong has to come up with new legislation.. FHFA owns the capital risk definition
Cong - Never mind.. they keep changing every 2 years and every 2 years a new committee is formed, which will bring the FHFA head to the hearing and ask, what are you doing about exit... They speak about safety and soundness and if any tough questions come up, the FHFA head will say, we will get back to you on it and we will work with you through the process in complete cooperation (this answer applies for the new FHFA head swearing in hearing too-- NOD for everything cong says until appointed)
Rinse and repeat
