The Office of the Comptroller of the Currency (OCC) is changing its regulation governing national bank investments that are designed primarily to promote the public welfare. This final rule simplifies the prior notice and self-certification requirements that apply to national banks' public welfare investments; permits eligible national banks to self-certify any public welfare investment; includes the receipt of Federal low-income housing tax credits by the project in which the investment is made (directly or through a fund that invests in such projects) as an additional way of demonstrating community support or participation for a public welfare investment; expands the types of investments that a national bank may self-certify by removing geographic restrictions; clarifies that the list of investments that were authorized to be made without prior approval now is illustrative of eligible public welfare investments; revises and expands the illustrative list of eligible public welfare investments; removes the private market financing requirement for public welfare investments; and makes clarifying and technical changes. Taken together, these changes will simplify procedural requirements and will make it easier for national banks to make public welfare investments, consistent with the underlying statutory authority.
