Evaluating a bank's system of internal controls is a fundamental step in the OCC's supervision process. This booklet contains a compilation of OCC Internal Control Questionnaires (ICQs) and verification procedures from the Comptroller's Handbook for National Bank Examiners and booklets of the Comptroller's Handbook that were published prior to January 2001. Booklets that were published after that time contain ICQs and verification procedures, either separately identified or incorporated into the examination procedures.
