In 1998, Congress amended the Federal Credit Union Act to establish minimum capital standards for federally-insured credit unions and to require the NCUA Board to adopt, by regulation, a system of "prompt corrective action" to restore the capital level of credit unions which become inadequately capitalized. The NCUA Board issued a proposed rule combining the components of prompt corrective action expressly prescribed by statute with those the statute required NCUA to develop to suit the distinctive needs and characteristics of credit unions. As revised to reflect public comments and to incorporate other improvements, the final rule establishes a comprehensive framework of mandatory and discretionary supervisory actions indexed to five statutory net worth categories; an alternative system of prompt corrective action for credit unions which meet the statutory definition of "new"; conforming reserve and dividend payment requirements; and procedures for reviewing and enforcing directives imposing prompt corrective action.
