The FDIC is adopting a rule on an interim basis to implement certain provisions of the Gramm-Leach-Bliley Act. The interim final rule impacts the FDIC's rules and regulations governing activities and investments of insured state banks. Under the rule, FDIC insured state nonmember banks must file a notice before they may conduct activities as principal through a subsidiary that a national bank can conduct only in a financial subsidiary. State nonmember banks must comply with four requirements to carry out these activities. Also, state nonmember banks along with their insured depository institution affiliates must have received a rating of not less than satisfactory under the Community Reinvestment Act. Under the rule, the FDIC may impose standards and prudential safeguards to insulate the bank from liability for activities of the subsidiary.
