The OCC has released its 2017 assessment schedule. Assessments are due March 31 and Sept. 30, based on Call Report information as of Dec. 31 and June 30, respectively, the OCC said. Marginal assessment rates were adjusted to 1.2% for 2017 due to inflation. Fees assessed on independent trust banks and independent credit card banks were also adjusted for inflation. The schedule continues to include a surcharge for national banks, federal savings associations and federal branches and agencies of foreign banks that require increased supervisory resources.
