The Federal Housing Regulatory Reform Act, Division A of the Housing and Economic Recovery Act of 2008 (HERA), requires the Director of Federal Housing Finance Agency (FHFA) to establish criteria based on the amount and type of capital held by a Federal Home Loan Bank (Bank) for each of the following capital classifications: adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. In addition, HERA provides that the critical capital level for each Bank shall be the amount of capital that the Director by regulation shall require. HERA also sets forth prompt corrective action (PCA) authority that the Director has for the Banks. To implement these new provisions, the FHFA is adopting this interim final rule to define critical capital for the Banks, establish the criteria for each of the capital classifications identified in HERA and delineate its PCA authority over the Banks.
