This final rule, Interpretive Ruling and Policy Statement (IRPS) 03-2, amends the Regulatory Flexibility Act provisions of NCUA's IRPS 87-2, Developing and Reviewing Government Regulations. The Regulatory Flexibility Act generally requires federal agencies to prepare analyses to describe the impact of proposed and final rules on small entities. Since 1981, the NCUA has defined small entity in this context to mean those credit unions with less than one million dollars in assets. This final rule redefines small entity to mean those credit unions with less than ten million dollars in assets. In addition, the rule amplifies a provision regarding NCUA's policy of reviewing all existing regulations every three years by stating that one-third of existing regulations will be reviewed each year and the public will receive notice of those regulations under review. The rule also updates IRPS 87-2 with a reference to the U.S. Small Business Administration guidance on implementation of the Regulatory Flexibility Act and to a Small Business Regulatory Enforcement Fairness Act requirement for publication of the factual basis supporting any certification that a particular rule will not have a significant economic impact on a substantial number of small entities.
