The Office of the Comptroller of the Currency (OCC) is amending the assessment formula it uses to assess independent trust banks. A trust bank is considered independent for purposes of this regulation if it specializes in trust activities and is not affiliated with a full-service national bank. Under the revised rate structure, all independent trust banks will be assessed based on balance sheet assets plus a minimum fee as provided by the OCC in the annual Notice of Comptroller of the Currency Fees (Notice of Fees). Independent trust banks with assets under management in excess of $1 billion would pay an additional amount based on a declining marginal rate, which also will be provided in the Notice of Fees.
