New mortgage insurance eligibility rules proposed earlier this month by the Federal Housing Finance Agency appear likely to cause some MIs to tweak their corporate structures and/or to raise additional capital, note industry observers. In its draft Private Mortgage Insurer Eligibility Requirements, the FHFA directed Fannie Mae and Freddie Mac to revise, expand and align their risk management requirements for mortgage insurance counterparties.The updated financial requirements incorporate a new, risk-based framework that ensures that approved insurers have a sufficient level of liquid assets from which to pay claims.
