The Board of Governors is amending appendix A of Regulation CC to delete the reference to the Pittsburgh check processing office of the Federal Reserve Bank of Cleveland and reassign the Federal Reserve routing symbols currently listed under that office to the head office of the Federal Reserve Bank of Cleveland. These amendments reflect the restructuring of check processing operations within the Federal Reserve System. The Board also is amending appendices A and E of Regulation CC to replace all references to Thomson Financial Publishing Inc. with more general references to "an agent of the American Bankers Association."
